Conselho Nacional de Desenvolvimento Científico e Tecnológico / The wastewater treatment is necessary to reduce the impact of river pollution in large cities. This treatment is generated a large amount of organic matter decanted, called sludge. In order to make use of organic waste and consolidate a model of sustainable agriculture, that has been employing throughout the world, the use of sewage sludge on farmlands. Organic fertilization has been commonly practiced as a source of nutrients, among them nitrogen, to attend the nutritional needs of tomato. This study evaluates the effectiveness of using sewage sludge by Station Treatment of Housing Journalist Orlando Dantas, from Companhia de Saneamento de Sergipe - DESO that is considered a domestic sewage, as a source of nitrogen for growth and yield of tomato cherry on Cambisoil, traditionally present in farmlands of Sergipe, and more studying the implications of its use in the physiology of tomato. The experiment was conducted in greenhouse located in the Biology Department (UFS), São Cristóvão / SE. The experimental design was completely randomized design with five treatments and five replications and two plants. The treatments were a combination of soil and increasing dosages of sewage sludge as the amount of available nitrogen in sewage sludge as also by the amount of N recommended for growing tomatoes. The treatments were T1: mineral fertilization, T2: no fertilization, T3: ½ sludge dose, T4: 2.0 sludge dose, T5: 4,0 sludge dose, considering the quantity of avalaible nitrogen on sludge, and also, N recommended to tomato cultivation. The growth of plants were determined by dry mass of roots and shoots of plants, number and fruit weight, root length. Variables such as net photosynthesis (A), stomatal conductance (gs), transpiration (E) and internal CO2 concentration (Ci) were made when the plants started flowering. There was greater root growth at T2 if compared to other treatments. For root, leaf, stem, shoot and total dry weight there were beneficial effect of sludge in relation to control. Regarding the number of fruit and tomato production, they were higher when there was organic fertilization, demonstrated the capacity of replaceable of this residue as a mineral fertilizer. There was effect in the variables of stomatal conductance and net photosynthesis at the rate of 2.0 mg dm-3 sludge showed the best response. As to the internal carbon concentration in leaves and photosynthesis rate, these parameters had an inversely proportional relationship and these variables are associated to photosynthesis activity. The case study leads us to consider a dose of 2.0 mg dm-3 the best for cherry tomato under greenhouse conditions.

Deste tratamento é gerado um grande volume de matéria orgânica decantada, denominado lodo de esgoto. Afim de fazer uso de resíduos orgânicos e consolidar um modelo de agricultura mais sustentável, é que vem se empregando, no mundo todo, o uso de lodo de esgoto em terras agricultáveis. Os lodos de esgotos são, de uma maneira geral, fertilizantes nitrogenados de liberação lenta. Além do N, os lodos de esgotos contém P e micronutrientes essenciais, como Fe e Zn. Este trabalho objetiva avaliar a eficiência do uso de lodo de esgoto cuja origem é a ETE do Conjunto Habitacional Jornalista Orlando Dantas, da Companhia de Saneamento de Sergipe DESO, caracteristicamente lodo doméstico, como fonte de nitrogênio para o crescimento e produção de tomate cereja num solo CAMBISSOLO, tradicionalmente presente em regiões produtoras de hortaliças em Sergipe, além de estudar as implicações de seu uso na fisiologia do tomateiro. O experimento foi realizado em casa de vegetação localizado no Departamento de Biologia da Universidade Federal de Sergipe, em São Cristóvão/SE. O delineamento experimental utilizado foi o inteiramente casualizado, com cinco tratamentos e cinco repetições e duas plantas úteis. Os tratamentos foram T1: adubação mineral, T2: sem adubação, T3: dose 0,5 lodo, T4: dose 2,0 lodo, T5: dose 4,0 lodo, conforme a quantidade de Nitrogênio disponível no lodo como, também, pela quantidade de N recomendada para o cultivo do tomate. Para avaliar o crescimento das plantas foram determinados a produção de massa seca das raízes e da parte aérea das plantas, número e peso de frutos, comprimento da raiz. Variáveis como fotossíntese líquida (A), condutância estomática (gs), transpiração (E), concentração interna de CO2 (Ci) foram feitas quando as plantas iniciaram o florescimento. Amostras de raízes e da parte aérea foram moídas e avaliadas quimicamente para determinação do teor N, segundo metodologia descrita pela Embrapa. Houve maior crescimento da raiz em T2 em relação aos demais tratamentos. Já para massa seca da raiz, das folhas, do caule, da parte aérea e total houve efeito benéfico do uso do lodo em relação à testemunha. Em relação ao número de frutos e produção do tomateiro, estes foram maiores quando houve adubação orgânica, mostrando ser este resíduo capaz de substituir adubação mineral. Quanto ao N acumulado nas raízes e na parte aérea, os menores valores obtidos foram na ausência de adubação. Houve influência do aumento da dose de lodo nas variáveis de condutância estomática, sendo a dose de 2.0 mg dm-3 de lodo a que teve a melhor resposta. Quanto à concentração de carbono interno na folha e fotossíntese líquida, estes parâmetros tiveram valores inversamente proporcionais, e a relação destas variáveis está no consumo de carbono para a síntese de carboidratos da fotossíntese. O estudo de caso leva-nos a considerar a dose de 2.0 mg dm-3 recomendável para o tomateiro cereja sob condições de estufa.

Several factors may limit the productivity of bean such as disease, however proper management coupled with the use of agricultural inputs can provide increased productivity. So the objective was to assess the present work rates and timing of application of plant growth promoter Booster® three bean cultivars and fungicides and their application timing on the effect of pyraclostrobin to cultivate pearl beans. The experiments were conducted in a factorial arrangement with three factors, for which nitrate reductase activity, chlorophyll index, height of insertion of first pod and plant disease severity, number of pods per plant and seeds per pod were evaluated, thousand grain weight and yield. Pearl cultivar showed higher productivity than cultivar splendor. The dose of 0.15 L ha-1 reduced the index Chlorophyll Falker and plant height cherry cultivar. The plant growth promoter used in V4 resulted in increased activity of the enzyme nitrate reductase, but without increases in productivity. Regarding the effect of the application of pyraclostrobin Comet® before topdressing increased the activity of nitrate reductase, plant height, number of seeds per pod and grain yield of pearl beans. / O Brasil é o maior produtor mundial de feijão. Diversos fatores podem limitar a produtividade do feijoeiro, como as doenças, no entanto o manejo adequado aliado ao uso de insumos agrícolas pode propiciar aumento de produtividade. Assim objetivou-se com o presente trabalho avaliar doses e épocas de aplicação do bioestimulante Booster® em três cultivares de feijoeiro e fungicidas e sua época de aplicação quanto ao efeito da piraclostrobina para a cultivar de feijoeiro pérola. Os experimentos foram instalados em arranjo fatorial com três fatores, para os quais foram avaliadas atividade da redutase do nitrato, índice de clorofila, altura de inserção de primeira vagem e de plantas, severidade de doenças, número de vagens por planta e de grãos por vagens, massa de mil grãos e produtividade. A cultivar pérola apresentou maior produtividade que a cultivar esplendor. A dose de 0,15 L ha-1 reduziu o Índice de Clorofila Falker e altura de plantas da cultivar pitanga. O bioestimulante aplicado em V4 resultou em maior atividade da enzima redutase do nitrato, no entanto, sem incrementos na produtividade. Quanto ao efeito da piraclostrobina a aplicação de Comet® antes da adubação de cobertura incrementou a atividade da redutase do nitrato, na altura de plantas, no número de grãos por vagem e na produtividade de grãos de feijoeiro pérola.

Esses alimentos além de satisfazer requerimentos nutricionais e sensoriais básicos desempenham efeitos fisiológicos benéficos que diminuiriam o risco de doenças crônicas cardiovasculares, cancerígenas ou outras. Existe uma grande variedade de produtos para fins especiais, sendo aqueles destinados a dietas de redução de açúcares um dos mais expressivos. Assim, as indústrias têm o desafio de desenvolver processamentos em condições amenas de operação, tempo e temperatura, provocando menores alterações de coloração, sabor e nutricionais. Com base nisso, a finalidade desse trabalho foi concentrar os nutrientes da goiaba vermelha e yacon, através da desidratação osmótica e desenvolver um doce em massa com as frutas desidratadas osmoticamente e acerola, de valor calórico reduzido através de processo contínuo. Primeiramente, foi realizado um estudo para otimizar a desidratação osmótica utilizando xarope de sorbitol e de sacarose. Os ensaios foram realizados utilizando planejamento fatorial completo, variando-se o tempo, temperatura e concentração da solução osmótica, visando a maximização da perda de umidade e minimização da incorporação de sólidos. Na desidratação osmótica utilizando xarope de sorbitol foram obtidas perdas de umidade de 35 a 43% % e incorporação de sólidos de 5,7 a 8% na goiaba vermelha e no yacon 53 a 55% de perdas de umidade e 6,02 a 6,46% de incorporação de sólidos. Os resultados obtidos mostraram que utilizando xarope de sorbitol se conseguem maiores perdas de umidade em relação ao xarope de sacarose, contudo há também uma maior incorporação de sólidos, mas isto seria irrelevante no caso de produtos de baixo valor calórico, nos quais o sorbitol é comumente utilizado, por apresentar um valor energético de 2,4kcal/g, enquanto que a sacarose fornece 4kcal/g. Outro objetivo foi também obter um doce em massa de goiaba vermelha, yacon e acerola, com um maior teor em sólidos de frutas que um produto convencional. Foram realizadas três formulações para análise sensorial, sendo utilizado o teste de aceitação. Os doces em massa tiveram boas médias de aceitação sensorial, variando de ¿gostei ligeiramente¿ a ¿gostei moderadamente¿, diferindo entre si (p< 0,05) nos atributos cor, sabor e impressão global, e não apresentando diferença significativa no atributo aroma. A formulação preferida foi com 50% goiaba vermelha, 30% acerola e 20% yacon, processada em tratamento térmico contínuo. Os resultados da caracterização química (pH, acidez e atividade de água) e física (sinerese, cor e textura) dos doces em massa mostraram concordância com os trabalhos encontrados na literatura. Através da avaliação microbiológica o produto foi considerado como ¿comercialmente estéril¿, indicando que o tratamento térmico foi eficiente para manter a estabilidade microbiológica do produto / Abstract: Concern about the relation between diet and health has greatly increased recently, stimulating the consumption of healthy, nutritive and functional foods, preferably of reduced caloric value, containing potentially health-protecting nutrients. In addition to satisfying the basic nutritional and sensory requirements, these foods play a beneficial physiological role in decreasing the risks of chronic cardiovascular diseases, cancer and other diseases. A great variety of special purpose foods exist, those destined for low sugar diets being the most prominent. Thus modern industry faces the challenge of developing processes operating under mild time/temperature conditions so as to minimize alterations in color, flavor and nutritional quality. Based on this idea, the objective of this research was to concentrate the nutrients of red guava and yacon by osmotic dehydration and develop a reduced calorie solid preserve using the osmotically dehydrated fruits plus West Indian cherry by way of a continuous process. Initially the osmotic dehydration process was optimized using sorbitol and sucrose syrups. A complete factorial experimental design was used for these trials, varying the time, temperature and concentration of the osmotic solution, aiming at maximizing moisture loss and minimizing solids incorporation. Osmotic dehydration using sorbitol syrup resulted in moisture losses of from 35 to 43% and solids incorporation between 5.7 and 8% for red guava and moisture losses of from 53 to 55% for yacon with solids incorporation from 6.02 to 6.46%. The results showed that higher moisture losses were obtained using the sorbitol syrup than with the sucrose syrup, although the solids incorporation was also higher. However, in low calorie products this is irrelevant since sorbitol is frequently used in such products due to its low energy value of 2.4kcal/g as compared to 4kcal/g for sucrose. A further objective was to prepare a solid preserve from red guava, yacon and West Indian cherry containing higher fruit solids content than the conventional product. Three formulations were prepared for the sensory acceptance test. The three formulations received good mean scores for acceptance, varying from ¿liked slightly¿ to ¿liked moderately¿, with significant differences (p£0.05) amongst the three for the attributes of color, flavor and overall impression but with no significant difference for aroma. The most preferred formulation was that containing 50% red guava, 30% West Indian cherry and 20% yacon, processed by a continuous heat treatment. The results of the chemical (pH, acidity and water activity) and physical (syneresis, color and texture) characterizations agreed with those of similar studies reported in the literature. The microbiological evaluation showed the product to be commercially sterile, indicating that the heat treatment was efficient in maintaining the microbiological stability of the product / Mestrado / Mestre em Tecnologia de Alimentos

GlobalGAP (previously EurepGAP) is a voluntary business-to-business standard for food audit that has recently achieved the greatest acceptance worldwide (Campbell, Lawrence & Smith 2006) boasting implementation numbers of over 80,000 farms in 80 countries. Compliance with the standard is verified by means of the third party certification (TPC) audit, and is designed to (GlobalGAP 2008) assure European retailers that exporting producers have met their criteria for safe and sustainable agriculture (GlobalGAP 2007b). In 2004, cherry growers in the Southern Interior of British Columbia became the first GlobalGAP certified producers in Canada. This novelty afforded a unique opportunity to observe the introduction of the standard in an industrialized country with well-established regulations and where the capacity of producers to undertake the process was relatively high. A qualitative methodology was used in case studies of two communities to inductively study the implementation of ‘safe and sustainable agriculture’ certification and generate relevant research questions for deeper examination. Sensitizing concepts emerging from observations of the TPC audits (n = 20) evolved into two primary research objectives; 1) to understand the practical application and diffusion of a TPC standard and 2) to explore the efficacy of the TPC standard as a mechanism to promote sustainable agriculture within certain pre-existing contexts. Forty-four follow up interviews were conducted with growers that chose to certify (n = 24), those that did not (n = 14), and other key actors (n = 3). This thesis examines the research objectives over three chapters. The introduction provides the local and global context along with a review of GlobalGAP, agri-food governance and the role of private certification and retailer power. Chapter two presents the technological and sociological factors that influenced the stages of the diffusion of GlobalGAP TPC and compares these factors and outcomes to the technological and sociological components of sustainable agriculture. In the conclusion, policy strategies are offered to maximize the potential for this tool to promote sustainable agriculture along with suggestions for future research on the topic. / Science, Faculty of / Resources, Environment and Sustainability (IRES), Institute for / Graduate

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Eugenia involucrata DC. is a native forest species in Brazil, and other countries in South America such as Argentina, Uruguay and Paraguay, with important economic, ecological and silvicultural. The species has edible fruit is widely used in cookery and has medicinal properties. Its seeds are recalcitrant, losing the viability and germination after collecting fruit, not supporting, thus avoiding long periods of storage. Because of this, we need studies to know the characteristics of the species, aiming at the production of quality seedlings. Thus, the overall objective of this study was to evaluate methodologies that can contribute to the propagation of Eugenia involucrata. They were evaluated the health quality, physical and physiological two lots of seeds, and different agents disinfectants for aseptic in vitro germination of seeds and different substrates, in order to ex vitro germination of the species. For in vitro establishment of nodal segments Eugenia involucrata were exposed to different disinfectants agents for the control of microbial contamination. Moreover, they also tested different pH values, sucrose and agar. The results indicated that Eugenia involucrata seeds present variations regarding the biometric features, high humidity and association with fungi. The filter paper substrate was not efficient for the germination of seeds of both lots evaluated. The vermiculite and grit:vermiculite in the ratio 1:1, gave the highest average of emerged seedlings. However, the seedlings did not develop appropriately if the vermiculite was disposed on the seeds, suggesting additional studies in this regard. For the in vitro establishment of nodal segments, tested disinfectants agents significantly decreased the fungal contamination in the explants, recommending the use of disinfectants agents Ca(ClO)2 3,0% (v/v) combined with NaClO 2,0% (v/v), however, these concentrations have not managed satisfactorily bacterial contamination. The pH was adjusted to 6,0 proved most efficient establishment of the explants in vitro. One can use 10g L-1 sucrose and 4g L-1 agar for the in vitro establishment phase nodal segments of Eugenia involucrata. / Eugenia involucrata DC. é uma espécie florestal nativa do Brasil, além de outros países da América do Sul, como Argentina, Uruguai e Paraguai, apresentando importância econômica, silvicultural e ecológica. A espécie possui frutos comestíveis sendo muito utilizados na culinária e apresenta propriedades medicinais. Suas sementes são recalcitrantes, perdendo a viabilidade e o poder germinativo após a coleta dos frutos, não suportando, assim, longos períodos de armazenamento. Por conta disso, são necessários estudos que permitam conhecer as características da espécie, visando a produção de mudas de qualidade. Desta maneira, o objetivo geral do presente trabalho foi avaliar metodologias que possam contribuir para a propagação vegetativa de Eugenia involucrata. Foram avaliados aspectos da qualidade sanitária, física e fisiológica de dois lotes de sementes, além de diferentes agentes desinfestantes para a germinação asséptica in vitro de sementes e diferentes substratos, visando à germinação ex vitro da espécie. Para o estabelecimento in vitro, segmentos nodais de Eugenia involucrata foram expostos a diferentes agentes desinfestantes, visando o controle da contaminação microbiana. Além disso, foram testados, também, diferentes valores de pH, sacarose e ágar. Os resultados obtidos indicaram que as sementes de Eugenia involucrata apresentam variações quanto aos aspectos biométricos, alto grau de umidade e associação com fungos. O substrato papel filtro não se mostrou eficiente para a germinação das sementes de ambos os lotes avaliados. Os substratos vermiculita e areia:vermiculita na proporção 1:1, proporcionaram as maiores médias de plântulas emergidas. No entanto, as plântulas não se desenvolveram de maneira adequada quando a vermiculita estava disposta sobre as sementes, sugerindo estudos adicionais a esse respeito. Para o estabelecimento in vitro de segmentos nodais, os agentes desinfestantes testados diminuíram significativamente a contaminação fúngica nos explantes, recomendando-se a utilização dos agentes desinfestantes Ca(ClO)2 a 3,0% (v/v) combinado a NaClO a 2,0% (v/v), entretanto, essas concentrações não controlaram de maneira satisfatória a contaminação bacteriana. O pH ajustado para 6,0 mostrou-se mais eficiente ao estabelecimento in vitro dos explantes. Pode-se utilizar 10g L-1 de sacarose e 4g L-1 de ágar durante a fase de estabelecimento in vitro de segmentos nodais de Eugenia involucrata.

Tonality is a term often used to describe the music of the common practice period (roughly 1600-1900). This study examines the music of mid twentieth-century jazz composer Thad Jones in light of an extended common practice, explicating ways in which this music might be best understood as tonal. Drawing from analyses of three of Jones’s big band compositions: To You, Three and One, and Cherry Juice, this study examines three primary elements in detail. First is Jones’s use of chord-scale application techniques in the orchestration over various chordal qualities represented by the symbols, revealing traditional as well as innovative methods by Jones. Second is Jones’s use of harmonic progressions, demonstrating his connection to past practice as well as modern jazz variations. Third is Jones’s use of contrapuntal connections and their traditional relationship to functional tonality, but in a chromatic scale-based environment. Jones’s music is presented in this study to demonstrate a tonal jazz common practice that represents an amalgamation of traditions including twentieth-century scale-based procedures, Renaissance and early twentieth-century modality, eighteenth- and nineteenth-century voice leading schemas, and Baroque and Classical descending-fifth progressions. Also included as an appendix is a list of possible note errors in the published scores of To You, Three and One, and Cherry Juice.

Rapporten innehåller en bakgrundsdel med fakta om fågelbär som trädslag. Den innehåller en marknadsplan som studerar marknaden för körsbärsträ i Sverige och Europa, främst i Tyskland. I studien finns också en skötselplan för fågelbärsparcellerna i lövskogsförsöket på Mellomgården, Lerdala. Marknadsanalysen är gjord utifrån fakta från svensk och tysk litteratur och skötselplanen är ett resultat av mätningar och observationer i fält på den aktuella platsen. Marknadsanalysen visar att marknaden för fågelbär är begränsad i Sverige och att en generell prisnivå inte finns. Däremot är marknaden större i Tyskland och därifrån finns det flera prisexempel. Skötselplanen påpekar att en gallring omgående är nödvändig i försöket. Den huvudsakliga slutsatsen är att fågelbär med rätt skötsel kan uppnå en bra kvalitet och på så vis matcha kraven på marknaden.

This thesis deals with the determination of vitamin C in different varieties of cornelian cherry (Cornus mas) and mountain ash (Sorbus aucuparia). The theoretical part describes the botanical characteristics of both plants, the extension in the CZ and in the world, methods of reproduction, the content of meaningful health substances and the importance of both plants in food-processing industry. Attention is paid to vitamin C, which is in their fruits in high quantity. Conclusion of the theoretical part discusses various methods of determination of vitamin C. The aim of the experimental part was to comparison of the vitamin C content in different varieties cornelian cherry and mountain ash. The chosen method for the determination of vitamin C by high performance liquid chromatography (HPLC) with UV detection was first tested on standards. Selected validation parameters of this method was then determined. Validated method was used to determine the content of vitamin C in nine varieties cornelian cherry and six varieties of the mountain ash. For comparison were also tested some samples of the determination of total vitamin C after reducing dehydroascorbic acid by using dithiothreitol (DTT).

Die Broschüre fasst die Ergebnisse von Untersuchungen zum Süßkirschenanbau mit Regenschutzüberdachung zusammen. Unter der Überdachung ist der Anteil an geplatzten Früchten bedeutend geringer. Um den Anbau wirtschaftlich zu gestalten, sollte die Pflanzung nur mit ertragreichen Sorten mit großen, festen Früchten an geeigneten, nicht spätfrostgefährdeten Standorten erfolgen. Notwendig ist ein intensives Anbausystem mit schwach wachsenden Unterlagen sowie eine bedarfsgerechte Bewässerung und Düngung. Ebenso wichtig ist eine ausreichende Befruchtung. Bei einer Standzeit der Anlage von 20 Jahren, einem mittlerem Ertrag von 100 dt/ha und einem durchschnittlichem Erlös von 2,25 €/kg ist der Anbau von Süßkirschen unter einer Regenschutzüberdachung wirtschaftlich.

Nutrient concentrations in plant tissues are directly correlated with the nutritional status and productivity of fruit trees. Plant tissue testing is one of the most effective and accurate methods to determine nutritional status of perennial plants. Tissue test analyses were performed on tart cherry (Prunus cerasus) and peach (Prunus persica) leaves to validate tissue sufficiency levels used in Utah and to determine optimal timing of tissue sampling for prediction of harvest nutrient status, focusing on phosphorus (P), potassium (K), calcium (Ca), iron (Fe), and zinc (Zn). Sufficiency limits that were adopted in Utah were developed in the 1960s from research data accumulated from the primary fruit growing regions in the United States. Limited research has been conducted under Utah growing conditions. Tissue nutrient concentrations over time correlated well with current sufficiency limits and observed nutrient deficiencies in the field. Tissue concentrations of P, K, Fe, and Zn were found to be chronically low in Utah orchards. Plant tissue data demonstrates that mid-season sampling can predict nutrient status at harvest. Mid-season sampling also allows time for corrective adjustments to maintain sufficiency levels and reach optimal fruit production. Nutrient management practices are commonly applied annually to increase yield, fruit quality, and overall health of an orchard. Yield was measured on previously treated tart cherry orchards to determine residual effect on tree nutrient status. Orchards were treated 2 to 3 years prior with rate-response formulations of P and K; one has since adopted recommended fertilizer rates for optimizing tart cherry production in Utah and the other continued with their less aggressive management practices. The less aggressively managed orchard showed trends across treatments, but differences were not significant. Annual fertilizer applications may not immediately show effect during year of application, but long term management is essential for overall productivity of orchards.
