The experiment was conducted in the municipality of de Matinha-MA. The experimental design was a completely randomized design, with the arrangement in split plot design with 6 repetitions for the evaluation of agronomic characteristics and 30 repetitions for the characteristics morfogenicas and structural, and factorial 4x5 being (four densities of palm trees and five generations of tillers and ten repetitions) for demographic characteristics. The plots were composed of the densities (80, 131, 160 adult palm trees/ha) and monoculture and the subplots stations (rainy and dry season). For total production of fodder, leaf production, the density with 80 palm/ha presented values equal and/or higher than the monoculture and the other densities. While that for rate of leaf appearance, phyllochron, leaf elongation rate, rate of elongation of the stem, the results obtained in SSP's during the dry period were higher than the monoculture, while that in the rainy season, the SSP with 131 palm/ha was higher than the other densities and monoculture for the characteristics of rate of leaf appearance and leaf elongation rate. Already for the structural characteristics; the duration of life of leaf did not differ between periods and between treatments, with respect to the final length leaf, in the dry season the system with 160 palm/ha was greater than the monoculture, however, did not differ from other SSP's, for the rainy season, the SSP's showed similar results to monoculture. For the tiller density live, during the rainy season the systems 80 and 131 palm/ha differed from monoculture, however, the system of 131 palm/ha obtained the highest number of tillers killed. For the rate of appearance, the system of 80 palm/ha showed similar results to monoculture and different to other SSP's in generations one, two, three and five. For the mortality rate, the system with 131 palm/ha was the only treatment the highest rate in all generations in relation to monoculture. For the rate of survival, it was observed that the treatment with 160 palm/ha that equated to the results obtained in monoculture in five generations. In relation to the index of stability of tillers, in the first two generations the system with 80 palm/ ha was higher than the other densities, to the following generations the values obtained were equaled. For the volumetric density, in the rainy season, the system of 80 palm/ha was superior to the systems 131 and 160 palm/ha, however, did not differ in monoculture. Silvopastoral Systems with 80 palm/ha of babassu promote higher total production of grass, leaves, stalks and lower rate of senescence, however for some characteristics as TApF, TAIF and CFF pastures with 131 palm/ha had a better performance. Monoculture and SSP with 80 and 131 palm/ha have higher rate of renewal of tissues, with high rates of occurrence and mortality of tillers, resulting in greater tiller density. However, the pasture with 80 and 160 palm/ha and the monoculture showed high survival rates of suckers along the generations as compensation mechanism. Thus, densities of palm trees between 131 and 160 palm/ha can compromise the renewal of the canopy, due to low TApPb. / Objetivou-se com presente trabalho avaliar as características agronômicas, morfogênicas e estruturais, além da densidade populacional de perfilhos e dinâmica de perfilhamento do capim-Marandu em sistemas silvipastoris com três densidades de palmeiras de babaçu e em monocultura. O experimento foi conduzido no Município de Matinha-MA. O delineamento adotado foi o inteiramente casualizado, com o arranjo em parcelas subdivididas com 6 repetições para a avaliação das características agronômicas e 30 repetições para as características morfogênicas e estruturais e, arranjo fatorial 4x5 sendo (quatro densidades de palmeiras e cinco gerações de perfilhos e dez repetições) para as características demográficas. As parcelas foram constituídas pelas densidades (80, 131, 160 palmeiras adultas/ha) e monocultura e nas subparcelas as estações (Chuvosa e Seca). Para produção total de forragem, produção de folhas, a densidade com 80 palm/ha apresentou valores iguais e/ou superiores a monocultura e as demais densidades. Enquanto que para taxa de aparecimento foliar, filocrono, taxa de alongamento foliar, taxa de alongamento do colmo, os resultados obtidos nos SSP s no período seco foram superiores a monocultura, enquanto que no período chuvoso, o SSP com 131 palm/ha foi superior as demais densidades e a monocultura para as características de taxa de aparecimento foliar e taxa de alongamento foliar. Já para as características estruturais; a duração de vida da foliar não diferiu entre períodos e entre tratamentos, com relação ao comprimento final foliar, no período seco o sistema com 160 palm/ha foi superior a monocultura, entretanto, não diferiu do demais SSP s, para o período chuvoso, os SSP s apresentaram resultados semelhantes a monocultura. Para a densidade populacional de perfilhos vivos, no período chuvoso os sistemas de 80 e 131 palm/ha diferiram da monocultura, entretanto, o sistema de 131 palm/ha obteve maior número de perfilhos mortos. Para a taxa de aparecimento, o sistema de 80 palm/ha apresentou resultados semelhantes a monocultura e diferentes aos demais SSP s nas gerações um, dois, três e cinco. Para a taxa de mortalidade, o sistema com 131 palm/ha foi o único tratamento a apresentar maior taxa em todas as gerações em relação a monocultura. Para a taxa de sobrevivência, observou-se que o tratamento com 160 palm/ha que equiparou-se aos resultados obtidos na monocultura nas cinco gerações. Já em relação ao índice de estabilidade de perfilhos, nas duas primeiras gerações o sistema com 80 palm/ ha foi superior as demais densidades, para as gerações seguintes os valores obtidos foram igualando-se. Para a densidade volumétrica, no período chuvoso o sistema de 80 palm/ha foi superior aos sistemas de 131 e 160 palm/ha, entretanto, não diferiu da monocultura. Sistemas silvipastoris com 80 palm/ha de babaçu promovem maior produção total de forragem, folhas, colmos e menor taxa de senescência, no entanto para algumas características como TApF, TALF e CFF as pastagens com 131 palm/ha tiveram melhor desempenho. Monocultura e SSP com 80 e 131 palm/ha possuem maior velocidade de renovação de tecidos, com altas taxas de aparecimento e de mortalidade de perfilhos, resultando em maior densidade populacional de perfilhos. No entanto, as pastagens com 80 e 160 palm/ha e a monocultura apresentaram altas taxas de sobrevivência de perfilhos ao longo das gerações como mecanismo de compensação. Dessa forma, densidades de palmeiras entre 131 e 160 palm/ha podem comprometer a renovação do dossel, devido à baixa TApPb.

Os modelos convencionais de agricultura exigem o uso intensivo de implementos e insumos agrícolas. Este fato, associado à falta de orientação técnica e ao manejo agrícola inadequado, leva a um desequilíbrio do meio com modificações na biota do solo e consequentes alterações no pH, ciclo da matéria orgânica e diminuição da capacidade adsortiva, favorecendo, por exemplo, os processos de contaminação do solo, águas superficiais e subterrâneas. As características e propriedades do solo, como a textura, estrutura e teor de matéria orgânica, associadas a fatores como o clima, relevo e concentração dos agrotóxicos aplicados, afetam a mobilidade destes, de acordo com suas propriedades físico-químicas, influenciando diretamente na sorção das substâncias potencialmente tóxicas. Neste contexto, a pesquisa teve como objetivo avaliar a utilização do agrotóxico carbofurano, buscando identificar possíveis riscos de contaminação e os fatores que influenciam no sistema solo-água-planta de acordo com o perfil de manejo agrícola. Para tanto, escolhemos duas vertentes sob o mesmo tipo de manejo e cultivo de pupunha, porém, com materiais de origem diferentes. A área de estudos está localizada no município de Iporanga, onde o cultivo de palmito pupunha e a utilização do ingrediente ativo carbofurano são comuns. Utilizando-se do método do perfil de manejo foram abertas trincheiras ao longo das duas vertentes para a descrição morfológica e coleta de solo. Foram coletados ainda palmito e água bruta próxima à área, visando a detecção de resíduos do agrotóxico. Os resultados das análises não indicaram resíduos de carbofurano em nenhuma das amostras, constatando que não há contaminação do solo, das águas superficiais e do palmito. O estudo mostrou que, apesar de se encontrarem sob um mesmo tipo de manejo, as diferenças de material de origem, características físicas e químicas e morfologia das vertentes resultariam em diferentes processos de retenção, transporte e transformação dos contaminantes. / The conventional models of agriculture demand the intensive use of agricultural implements. This fact, associated with poor technical guidance and inadequate agricultural management, leads to an imbalance of the environment with changes to the soil biota and consequent alterations in pH, organic matter cycle and reduction of adsorptive capacity, favoring, for instance, the contamination processes of the soil, surface water and groundwater. The characteristics and properties of the soils, such as texture, structure and organic matter content, associated with factors such as climate, landforms and the concentration of pesticides affect the mobility of the latter, as a consequence of their physico-chemical properties, directly influencing the sorption of potentially toxic substances. In this context, the goal of this research was to evaluate the use of the defensive carbofuran, in order to identify possible contamination risks and the factors that influence the soil-water-plant system according to the type of agricultural practices. Therefore, we chose two slopes under the same type of agricultural practices and cultivation of the pupunha palm tree, but with different source materials. The study area is located in the municipality of Iporanga, where the cultivation of the pupunha and the use of carbofuran are common. Using the crop profile method, trenches were opened along the two slopes for morphological description and collection of soil samples. Pupunha and water were also collected near the area, aiming the detection of agrotoxic residues. The results of the analysis did not indicate residues of carbofuran in any of the samples, noting that we found no contamination of the soil, surface water or the pupunha. The study showed that, although the two slopes were under the same type of agricultural practice, the differences in source material, physical and chemical characteristics and the morphology of the slopes would lead to differences in retention, transportation and transformation of the contaminants.

Geotextiles have been used for many years in different parts of the world to promote soil conservation and to combat erosion. Such geotextiles may be synthetic (usually some form of plastic, sometimes with wire), or natural (usually some form of fibrous material). Work carried out at the University of Wolverhampton (UK) on the effectiveness of mats made from palm tree leaves sourced from the Gambia, West Africa led to a research project funded by the EU, which ran from October 2005 to February 2009, comprising the participation of four EU countries (UK, Belgium, Hungary and Lithuania) and six developing” countries (Brazil, Gambia, South Africa, Thailand, China and Vietnam). Research carried out in South Africa used mats made from the leaves of the Lala palm (Hyperhene coriacea). These mats are easy to make, flexible, durable and completely biodegradable. They cover approximately 40% of the soil surface, allowing space for vegetation to emerge, and add 1.3 kg of dry organic matter to each m2 of soil. Furthermore, they have a water retention capacity of 1.8 l kg-1 m-2, their N, K, S and P percentages are high, they have low sodium and aluminium values and a favourable C/N ratio. Firstly, trials were done on 20 South African soils and 10 mine tailings materials using a rainfall simulator. The soils varied considerably with respect to their textural, chemical and mineralogical properties as well as annual precipitation and geological origin. Erosion parameters varied greatly within, and to a much lesser extent between, the two different materials. Several significant correlations were obtained. Sediment load (SL) had the best correlation with kaolinite content and with fine sand content, while for runoff, the best correlation was with organic carbon content. When the samples were covered with palm mats values for final infiltration rate (FI) percentage stable aggregates (SA) and inter-rill erodibility (Ki) values were similar to those of bare materials and the amount of runoff was slightly higher. SL, however, was reduced by +65%. The next stage was to carry out a range of field trials, using runoff plots. Plots at four localities (Bergville, Ladybrand, Roodeplaat and Mabula) were used. Results showed that average runoff under the palm mats decreased by between 38% and 70%, compared to bare soil. Sediment concentration under the mats decreased by between 38% and 89%, using three combinations of slope, mat density and mesh size. Splash erosion at Roodeplaat decreased by between 62% and 68%, while re-vegetation at Ladybrand and Mabula increased by between 38% and 58%, with organic carbon content and topsoil accumulation also increasing under the mats. Various trials (using both the rainfall simulator and runoff plots) were carried out to evaluate the effects of reduced mat density and increased mesh size. Results from the other participating countries (25% to 95% reduction in runoff) confirm that there is much potential to use organic, bio-degradable, easy to manufacture geotextiles such as palm leaf mats, especially to combine employment opportunities with enhanced environmental protection in many susceptible areas of South Africa. / Thesis (PhD)--University of Pretoria, 2014. / gm2014 / Plant Production and Soil Science / unrestricted

At the heart of the Etruscan city of Caere exists the Hypogaeum of Clepsina, an underground ritual chamber which scholars theorize to be a mundus, a liminal space linking the earthly realm with the underworld. It was a place where chthonic rituals were conducted in honour of the infernal gods and the ghosts of the ancestors, and its creation was tied to notions of civic foundation. The hypogaeum was constructed or renovated around 273 BC, at the time when the city of Caere was officially converted into a Roman praefectura. As one of the earliest projects undertaken in the newly established Roman Caere, the hypogaeum likely had a symbolic significance, reinforcing the establishment and stabilization of the territory under Roman control. Consequently, gaining a deeper understanding of the mundus of Caere, especially in terms of the cult worship and rituals that occurred within it, contributes to our knowledge of the role that religion played in Roman expansion in Italy during the Republican period. One of the most remarkable features of the hypogaeum is its painted niche, which is adorned with frescoes of two large palm trees. This thesis will explore the symbolic meaning of the palm trees, since these frescoes provide important clues as to the deity originally worshiped within the ritual chamber. The connection between the palm tree motif and Apollo will be investigated, as the god’s cult was imbued with strong solar, oracular, and chthonic associations in Etruria and Central Italy. He was syncretized with the Italic deity, Soranus, otherwise known as Śuri, a deity who received cult veneration at the important sanctuary of Caere’s port settlement, Pyrgi. Apollo Soranus, or Śuri, was a chthonic deity equated with the ruler of the underworld, and thus was a god altogether fitting to preside over the mundus of Caere. / Thesis / Master of Arts (MA) / The Hypogaeum of Clepsina is an underground ritual chamber in Caere, which scholars theorize to be a mundus, a liminal space where chthonic rituals were enacted in honour of the infernal gods. The mundus was tied to notions of civic foundation, which suggests that the hypogaeum’s construction (or renovation) around the year 273 BC, the time when the city of Caere was officially converted into a Roman praefectura, was a statement of Rome’s re-establishment of Caere. Thus, gaining a deeper understanding of the hypogaeum, especially the cults worshiped within it, contributes to our knowledge of the role that religion played in Roman expansion during the Republican period. The palm tree frescoes decorating the niche of the hypogaeum provide important clues as to the identity of the deity worshiped in the mundus. They are a reference to the god, Apollo Soranus, or Śuri, who was a chthonic deity fitting to preside over the mundus of Caere.

Le motif du palmier, qui apparaît dès la fin du IVe millénaire av. J.-C. en Égypte et en Mésopotamie, connaît une très large diffusion dans la Méditerranée antique, durant les second et premier millénaires av. J.-C. Il s’inscrit dans la tradition artistique, culturelle et religieuse d’un grand nombre de régions : le Levant, l’île de Chypre, la Grèce, la Méditerranée occidentale. Bâtie sur ce champ d’étude, géographiquement et chronologiquement très large, cette thèse examine la répartition du motif résultant de contacts et d’échanges entre les différentes civilisations et met en lumière l’élaboration d’une iconographie spécifique, propre à chacune d’entre elles. Certains développements symboliques – tels l’aspect cultuel du palmier et le rapprochement ou l’assimilation de l’arbre avec l’être humain, et plus particulièrement avec la femme –, apparaissent récurrents et permettent d’examiner la question de la continuité, ou non, du motif dans les différents groupes d’images étudiées et la façon dont la vision de l’arbre se manifeste dans chacune des civilisations. / The pattern of the palm-tree, which appears as soon as the end of the IVth millennium BC in both Egypt and Mesopotamia, experiences a vast diffusion across the Ancient Mediterranean world during the IInd and Ist millennium BC. Its style situates it in the artistic, cultural, and religious tradition of a large number of regions: the Levant, Cyprus island, Ancient Greece, and the Western Mediterranean. This thesis, built on wide geographical and chronological fields of study, investigates the geographical distribution of the pattern arising from contacts and exchanges between various civilizations and highlights how a specific iconography, proper to each civilization, has been elaborated. Some symbolic developments, such as the religious aspect of the palm-tree and the connection or assimilation of the tree to humans, in particular to women, appear recurrent and allow one to address the question of the continuity of the pattern in various picture samples and the way the view of the tree manifests itself in each of these civilizations.

Neste trabalho investigou-se planos e ações de educação ambiental do Parque Estadual "Carlos Botelho" (PECB) buscando possíveis relações com os distúrbios antrópicos em seu interior causados pela extração clandestina de palmito (Euterpe edulis). Esta área é considerada uma Unidade de Conservação de Proteção Integral e abrange 37.644,36 ha localizados na região sul do Estado de São Paulo. Sua porção que pertence ao Vale do Ribeira, em conjunto com outras unidades de conservação (Parque Estadual Turístico do Alto Ribeira e Parque Estadual Intervales), compõem um importante continuum ecológico do estado de São Paulo. Entre 1988 a 1994, apesar do poder público não destinar recursos institucionais para a formalização de atividades educacionais no PECB, iniciam-se as atividades de educação ambiental nessa área com o apoio financeiro do World Wildlife Fund (WWF) e da Fundação O Boticário de Proteção à Natureza. A partir da coleta e analise dos processos técnico-administrativos, dos relatórios de projetos e das atas de reunião do Parque, referentes ao período de 1988 a 2000, obteve-se os elementos necessários para compreender o histórico do Programa e sua fundamentação pedagógica. A metodologia adotada foi a de estudo de caso. Foram compilados também dados secundários sobre a extração de palmito na polícia ambiental e delegacia da região e realizadas entrevistas com indivíduos que, de algum modo, estão ligados à rede de extração de palmito e à população do entorno. Foi elaborado um diário de campo, com registros fotográficos e registros de reuniões entre setembro de 1999 a novembro de 2000, onde se registrou as atividades do Programa de Educação Ambiental e Uso Público do Parque. Neste contexto, procurou-se identificar a forma com que os distúrbios antrópicos, mais especificamente a extração clandestina de palmito, são trabalhados na gestão do Parque e mais especificamente no Programa de Uso Público, no subprograma de educação ambiental. Constata-se a carência de um tratamento mais aprofundado do conflito como estratégia privilegiada para se fazer educação ambiental. / The main objective of this work was to investigate plans and actions of environmental education developed by "Carlos Botelho" State Park (CBSP) related to riots caused by the clandestine extraction of the heart of palm Euterpe edulis. This area (37,644.36 ha) is located in the south of the state of São Paulo and it is considering Integral Unit of Conservation and Protection. The Ribeira Valley, which composes an important ecological continuum area, is formed by other two units of conservation (Alto do Ribeira Tourist State Park and Intervales State Park). From 1988 to 1994 the brazilian government did not give any support to promote environmental educational activities at CBSP, but it was possible to start the environmental education program, which was supported by the following no governmental organizations: World Wildlife Fund (WWF) and Boticário Foundation to Nature Protection. Based on the collected and analyzed administrative technical processes, project reports and acts of meeting occurred at CBSP during the period of 1988 to 2000, it was possible to obtain the necessary elements to understand the environmental program historic and how it was base on. The methodology adopted was the case study. It was compiled a secondary data about the heart of palm extraction, which were given by the policy and people from the neighborhood of the park and individuals who had been in contact with the environmental program or other activities developed by the park as well as the extraction of the heart of palm Euterpe edulis were interviewed. From September 1999 to November 2000 a field daily was elaborated and photos, meetings and activities of the environmental education program and public use developed by the park were registered. In this context and considering the environmental education subprogram, it was identified how the riots, specifically the clandestine extraction of the heart of palm Euterpe edulis, has been incorporated in the management of the park. It was found that the clandestine extraction of the heart of palm Euterpe edulis is not treated as it should be to guarantee the environmental education program efficiency.

It is necessary to identify a system that ensures the proper growth of plants of these species. In this context, these works provide alternatives for producing seedlings with adaptability for family farms of southern half of Rio Grande do Sul. The effect of different substrates on initial growth of the seedlings and the appropriate level of shading for their initial development were determined. The seedlings were grown on Estação Experimental Cascata, Embrapa Clima Temperado. The experiments reported in Chapters I determine the effect of different substrates. The seedlings grew from seeds originated in a family farm located in the municipalities of Tabai and Pelotas, RS. A combination of different substrates was used, represented by the treatments T1 - Plantmax®, T2 - forest soil, T3 - clayey soil, T4 - forest soil:clayey soil 1:1 (v:v), T5 - forest soil:carbonized rice husk 3:1 (v:v), T6 - forest soil:carbonized rice husk 1:1 (v:v), T7 - forest soil:rice husk in natura 1:1 (v:v), T8 - clayey soil:carbonized rice husk 3:1 (v:v), T9 - clayey soil:carbonized rice husk 1:1 (v:v), T10 - clayey soil:rice husk in natura 1:1 (v:v). The experimental design consisted of randomized blocks and the study used a (1 specie x 10 substrates) factorial scheme. Four replicates were used in each experimental design with four seedlings. The seedlings were transplanted into 2 dm³ plastic bags in greenhouse conditions, from January to September, 2009. The experiments were assessed fortnightly considering plants length, stem diameter, number of leaves, number of leaflets, leaflets length, roots length, physical properties of the substrates, macronutrients content of the substrates, and percentage of plants survival at the end of last evaluation. The experiments reported in Chapters II used plants grown from seeds of a family farm located in the municipality of Pelotas, RS. The effect of luminous intensity on palm trees growing in the field was assessed in the experiments. The palm trees were planted in different shading levels: S1 - 0%, S2 - 16%, S3 - 42% and S4 - 73%. 10 The shading was obtained with shade screen for each level of reduced incident radiant, it was placed over each plot represented by a structure of wooden beams with 2.10 m long, 0.70 m tall and 0.50 m wide. The experimental design was randomized blocks consisting of four replications. Each sampling unit was represented by three plants of each species, using 0.30 m row spacing, in the field during nine months. These experiments evaluated fortnightly plants length, stem diameter, number of leaves, number of leaflets, leaflets length, solar radiant incident on the plants, chlorophyll content of plants, roots length, soil physical properties, macronutrients content of soil, and percentage of survival at the end of last evaluation. Data were analyzed using the program statistical program WinSat. / O cultivo das espécies de palmeira-juçara Euterpe edulis (Mart.) e da palmeira-real Roystonea regia (Kunth) não possui registros de estudos focados para o Sul do Rio Grande do Sul, tornando-se necessário identificar um sistema com potencial para assegurar bom desenvolvimento das plantas destas espécies. Neste contexto, estes trabalhos forneceram alternativas de produção de mudas adaptadas à metade sul do Rio Grande do Sul, passível de utilização na agricultura familiar. Foi avaliado o efeito de diferentes substratos sobre o desenvolvimento inicial das mudas, bem como, identificou-se o nível de sombreamento adequado para o desenvolvimento inicial das mudas. Os trabalhos foram executados na Estação Experimental Cascata, Embrapa Clima Temperado. Para o Capítulo I, Estudos do efeito de diferentes substratos, utilizou-se plantas produzidas através de sementes em uma propriedade agrícola familiar localizada nos Municípios de Tabai-RS e Pelotas-RS. Foi utilizada a combinação de diferentes substratos representados pelos tratamentos: T1 - Plantmax®, T2 - solo mato, T3 - solo argiloso, T4 - solo mato:solo argiloso 1:1 (v:v), T5 - solo mato:casca de arroz carbonizada 3:1 (v:v), T6 - solo mato:casca de arroz carbonizada 1:1 (v:v), T7 - solo mato:casca de arroz in natura 1:1 (v:v), T8 - solo argiloso:casca de arroz carbonizada 3:1 (v:v), T9 - solo argiloso:casca de arroz carbonizada 1:1 (v:v), T10 - solo argiloso:casca de arroz in natura 1:1 (v:v). O delineamento experimental adotado foi de blocos ao acaso, com quatro repetições e cada unidade experimental composta por quatro plantas, sendo transplantadas para sacos plásticos de 2 dm3, em condições de casa de vegetação, no período de janeiro a setembro de 2009. Determinaremos para estes experimentos avaliar com intervalos quinzenais o comprimento das plantas; diâmetro do colo; número de folhas; número de folíolos; comprimento de folhas; comprimento das raízes; propriedades físicas dos substratos; teor de macronutrientes dos substratos; e 8 percentagem de sobrevivência das plantas ao final da ultima avaliação. Já para os experimentos Capítulo II, utilizou-se plantas produzidas através de sementes de uma propriedade familiar localizada no Município de Pelotas-RS, avaliado o efeito da intensidade luminosa sobre o desenvolvimento das palmeiras a campo, sendo estas plantadas em diferentes níveis de sombreamento: S1 - 0%, S2 - 16%, S3 - 42% e S4 - 73% de sombreamento. Estes sombreamentos foram obtidos com tela de sombrite para cada nível de redução da radiação incidente, colocada sobre cada parcela representada por uma estrutura de caibros de madeira medindo 2,10 m de comprimento, 0,70 m de altura e 0,50 m de largura. O delineamento experimental adotado foi de bloco ao acaso, compostos por quatro repetições, sendo cada unidade amostral representada por três plantas de cada espécie com espaçamento de 0,35 m entre linha, durante nove meses a campo. Determinamos para estes experimentos avaliar com intervalos quinzenais o comprimento das plantas; diâmetro do colo; número de folhas; número de folíolos; comprimento folhas; radiação solar incidente sobre as plantas; teor de clorofila das plantas; propriedades físicas do solo; teor de macronutrientes do solo; e percentagem de sobrevivência das plantas ao final da ultima avaliação.

L’autre intérêt concerne les préoccupations historiques du poème, lesquelles déterminent l’atmosphère qui s’en dégage et qui prévalait lors de sa composition, ses circonstances d’origine, sa date de composition et l’identité de son auteur. Un troisième pôle de l’exégèse, proche du premier, et en opposition avec le second, étudie le texte pour lui-même sans qu’il ne soit ancré dans son contexte historique. La structure du texte est décortiquée d’une part pour découvrir sa beauté technique et d’autre part pour voir comment elle guide le lecteur vers une compréhension optimale de l’instruction du psaume. Les caractéristiques de notre travail sont doubles : 1) être fidèle à l’approche exégétique historico-critique ; 2) apporter une pointe de modernité par le biais de l’analyse structurelle dans le chapitre correspondant. Parmi les résultats les plus probants, on notera que la métaphore végétale du bourgeonnement signifie que justes et méchants ont droit à la vie. Mais alors que celle des justes est restaurée, soutenue et garantie par le Seigneur, cette dernière ne prend pas de part active dans l’existence et la rétribution des méchants. / An analysis of the Hebrew text of psalm 92 is offered. Being a song, the first purpose of this work is to examine the poetic processes that it entails. The other focus pertains to the historical concerns of the poem, insofar as they determine its climate, the one that prevailed as it was composed, the circumstances of its origin, the date of composition and the identity of its author. A third pillar of the exegesis, close to the first one and in opposition to the second, is to study the text for its own sake without regard for its historical context. The structure of the text is scrutinized to, on the one hand, discover its technical beauty and on the other hand to see how it guides the reader towards an optimal understanding of the teaching of the poem. In plain: the characteristics of our work are twofold: 1) to be faithful to the historico-critical exegetic approach; 2) to bring a zest of modernity thanks to a structural analysis in the chapter on structure. Among the evidence-based results, we shall observe that the vegetal metaphor of burgeoning means that the just and the wicked have the right to live. However, if that of the just is restored, sustained and guaranteed by the divinity, the latter shall take no active part in the existence and retribution of the wicked.

[EN] The management of Rhynchophorus ferrugineus (Coleoptera: Dryophthoridae), the worst threat for palm trees worldwide, consists in several preventive and curative techniques, but because of its low efficacy the insect still causes major economic and landscape losses. In order to define aspects that have facilitated its rapid dispersal and contribute to improving its management, the effects of vision and flight, which influence the mobility of R. ferrugineus, have been analysed. The chromatic preference of R. ferrugineus has been studied by analysing their captures in coloured bucket traps. Black traps capture the highest number of insects compared with the other colours studied, both when they contain olfactory attractants, as when these compounds are not used, demonstrating that colour by itself is a crucial attraction factor. Moreover, the spectral reflectance of studied colours and of some P. canariensis tissues has been analysed. The wavelength spectrum of black shows great similarity to that of fibres of P. canariensis, so this may be the reason why R. ferrugineus prefers this colour. Regarding sex ratio of the insect in traps, female captures are significantly greater in those baited with olfactory attractants. However, a higher number of female captures does not always occur when these compounds are not used. On the other hand, the study of sex ratio in natural populations of the insect demonstrates that the proportion is one female per male. Therefore, the greater number of captures of females in commercial traps is due exclusively to their greater attraction towards the olfactory attractants used. Another of the analysed aspects has been the flight potential of R. ferrugineus under laboratory conditions. In order to know more about the mobility of this insect, different parameters have been studied using a computer-monitored flight mill. The selected parameters used to define the R. ferrugineus flight potential have been the number of flights, total distance flown, longest single flight, flight duration, and average and maximum speed. Moreover, the influence of sex, body size, and age of the adults on the aforementioned parameters has been examined. R. ferrugineus sex does not have a significant effect on the compared flight parameters. The body size in females is significantly greater, but this does not influence their flight potential. A higher percentage of flight is observed for adults with an age range of 8-23 days old, compared to the 1-7 day old adults. However, age does not significantly influence their flight potential. By analysing the longest single flight undertaken by each adult, up to 63% of the insects can be classified as short-distance flyers (<500m), 27.3% as medium-distance flyers (500-5000m), and >9% as long-distance flyers (>5000m). Finally, the flight behaviour and dispersal of R. ferrugineus have been analysed under field conditions using the mark-release-recapture method. This test focused on detecting the influence of different factors, such as sex, temperature, relative humidity, and solar radiation, in the take-off and dispersal of the adult insects. Take-off probability of R. ferrugineus adults is significantly greater in males Moreover, this probability increases when temperature and solar radiation rise. Concerning the insect dispersal by flying, the number of recaptures is influenced by temperature, increasing significantly when this factor increases. Likewise, dispersal distances also increase significantly as temperatures rise. The insect tends to fly distances <500m (77.1% of recaptured adults), following the same tendency observed in studies performed using the flight mill. However, R. ferrugineus is able to travel up to 7km, being recorded under laboratory conditions a potential flight up to 20km. To conclude, dispersal time of the adults is very short (more than 90% of the adults were recaptured during the first 7 days), being significantly lower when relative humidity increases. / [ES] El manejo de Rhynchophorus ferrugineus (Coleoptera: Dryophthoridae), una de las peores amenazas para las palmeras en el mundo, se lleva a cabo mediante la aplicación de diversas técnicas de prevención y control, pero debido a la baja eficacia de éstas la plaga continúa causando importantes pérdidas económicas y paisajísticas. Para definir los aspectos que han intervenido en su dispersión y contribuir a mejorar su manejo, se ha analizado el efecto de la visión y el vuelo en la movilidad de los adultos de R. ferrugineus. Se ha estudiado la preferencia cromática mediante el análisis de sus capturas en trampas cubo coloreadas. Las trampas negras capturan el mayor nº de insectos en comparación con el resto de colores estudiados, tanto cuando contienen atrayentes olfativos como cuando no los contienen, demostrando que el color por sí mismo es un factor importante de atracción. Además, se ha analizado el espectro de longitud de onda de los colores estudiados y de diversos tejidos de P. canariensis. El espectro del color negro muestra gran similitud con el de las fibras de P. canariensis, es por esto por lo que R. ferrugineus podría presentar esta preferencia. En relación a la proporción de sexos en trampas que contienen atrayentes olfativos, las capturas de hembras son significativamente más elevadas. En cambio, sin éstos no siempre se produce un mayor nº de capturas de este sexo. Por otro lado, el estudio de la proporción de sexos en poblaciones naturales muestra una ratio de una hembra por macho. Por tanto, las mayores capturas de hembras en trampas se deben a una mayor atracción de éstas hacia los atrayentes olfativos. Otro aspecto estudiado ha sido el potencial de vuelo de R. ferrugineus bajo condiciones de laboratorio. Con la finalidad de conocer la movilidad de este insecto se han analizado diversos parámetros mediante la utilización de un molinillo de vuelo computerizado. Los parámetros estudiados han sido: nº vuelos, distancia total volada, vuelo más largo, duración del vuelo y velocidades media y máxima. Además, se ha analizado como influye el sexo, el tamaño del cuerpo y la edad de los adultos en dichos parámetros de vuelo. El sexo de R. ferrugineus no muestra un efecto significativo sobre los parámetros de vuelo comparados. El tamaño del cuerpo de las hembras es significativamente mayor, pero no influye estadísticamente en su potencial de vuelo. En adultos con edades de entre 8-23 días se observa un mayor porcentaje de vuelo que en aquellos con 1-7 días de edad. En cambio, la edad no influye significativamente sobre su potencial de vuelo. Al analizar el vuelo más largo, obtenemos que >63% de los insectos se clasifican como voladores de corta distancia (<500m), el 27.3% de media distancia (500-5000m), y >9% de larga distancia (>5000m). Finalmente, se ha analizado en campo el comportamiento de vuelo y dispersión de R. ferrugineus mediante la técnica de marcaje-suelta-recaptura. Este ensayo ha permitido estudiar la influencia del sexo, la temperatura (Tª), la humedad relativa y la radiación solar, en el despegue y dispersión de los adultos. La probabilidad de despegue de R. ferrugineus es significativamente mayor en machos. Además, esta probabilidad se incrementa cuando la Tª y la radiación solar aumentan. Respecto a la dispersión del insecto mediante el vuelo, el nº de recapturas se ve influenciado por la Tª, aumentando significativamente cuando ésta se incrementa. De la misma manera, las distancias de dispersión también se incrementan significativamente a media que lo hace la Tª. El insecto tiende a volar distancias <500m (77.1% de los adultos recapturados), siguiendo la misma tendencia observada en laboratorio. No obstante, R. ferrugineus es capaz de recorrer hasta 7km, llegando a registrarse vuelos potenciales en laboratorio de hasta 20km. Por último, el tiempo de dispersión de los adultos es muy corto (>90% se recapturaron en los 7 primeros días), reduciéndose / [CAT] El maneig de Rhynchophorus ferrugineus (Coleoptera: Dryophthoridae), una de les pitjors amenaces per a les palmeres en tot el món, es porta a terme mitjançant l'aplicació de diverses tècniques de prevenció i control, però degut a la baixa eficàcia d'aquestes l'insecte continua causant importants pèrdues econòmiques i paisatgístiques. Per a definir els aspectes que han intervingut en la seua dispersió i contribuir a la millora del seu maneig, s'ha analitzat l'efecte que tenen la visió i el vol en la mobilitat dels adults de R. ferrugineus. S'ha estudiat la preferència cromàtica mitjançant l'anàlisi de les seues captures en trampes poal acolorides. Les trampes negres capturen el major nombre d'insectes en comparació amb la resta de colors estudiats, tant quan contenen atraients olfactius com quan no els contenen, demostrant que el color per ell mateix és un factor important d'atracció. A més, s'ha analitzat l'espectre de longitud d'ona dels colors estudiats i de diversos teixits de P. canariensis. L'espectre del color negre mostra gran similitud amb el de les fibres de P. canariensis, és per açò pel que R. ferrugineus podria presentar aquesta preferència. En relació a la proporció de sexes a les trampes que contenen atraients olfactius, les captures de femelles són significativament més elevades. En canvi, sense aquests no sempre es produeix un major nombre de captures d'aquest sexe. Per altra banda, l'estudi de la proporció de sexes en poblacions naturals demostra que la ràtio és d'una femella per mascle. Per tant, les majors captures de femelles en trampes es deuen a una major atracció d'aquestes cap als atraients olfactius utilitzats. Altre aspecte estudiat ha sigut el potencial de vol de R. ferrugineus sota condicions de laboratori. Amb la finalitat de conèixer la mobilitat d'aquest insecte s'han analitzat diversos paràmetres mitjançant la utilització d'un molinet de vol computeritzat. Els paràmetres estudiats han sigut: nombre de vols, distància total volada, vol més llarg, duració del vol i velocitats mitjana i màxima dels vols. A més, s'ha analitzat com influeixen el sexe, el tamany del cos i l'edat dels adults en dits paràmetres de vol. El sexe de R. ferrugineus no mostra un efecte significatiu sobre els paràmetres de vol comparats. El tamany del cos de les femelles és significativament major, però no influeix estadísticament en el seu potencial de vol. En adults amb edats d'entre 8-23 dies s'observa un major percentatge de vol que en aquells amb 1-7 dies d'edat. En canvi, l'edat no influeix significativament sobre el seu potencial de vol. En analitzar el vol més llarg, obtenim que més del 63% dels insectes es classifiquen com voladors de curta distància (<500m), el 27.3% de mitja distància (500-5000m), i >9% de llarga distància (>5000m). Finalment, s'ha analitzat en camp el comportament de vol i dispersió de R. ferrugineus mitjançant la tècnica de marcatge-solta-recaptura. Aquest assaig ha permès estudiar la influència del sexe, la temperatura, la humitat relativa i la radiació solar, en l'enlairament i dispersió dels adults. La probabilitat d'enlairament de R. ferrugineus és significativament major en mascles A més, aquesta probabilitat s'incrementa quan la temperatura i la radiació solar augmenten. Respecte a la dispersió de l'insecte mitjançant el vol, el nombre de recaptures es veu influenciat per la temperatura, augmentant significativament quan aquesta s'incrementa. De la mateixa manera, les distàncies de dispersió també s'incrementen significativament a mesura que ho fa la temperatura. L'insecte tendeix a volar distàncies <500m (77.1% dels adults recapturats), seguint la mateixa tendència observada en laboratori. No obstant, R. ferrugineus és capaç de recórrer fins a 7km, arribant-se a registrar vols potencials en laboratori de fins a 20km. Per últim, el temps de dispersió dels adults és molt curt (>90% es recapturaren en els 7 primers die / Ávalos Masó, JA. (2015).
