In this context, the objective was to evaluate the hormetic effect of glyphosate in common bean submitted to different conditions of abiotic stress and the use of techniques that can maximize results, such as the use of diazotrophic bacteria. The experiments were conducted in experimental areas of the farm Education Research and Extension of the Faculty of Ilha Solteira - UNESP in clayey Red Oxisol. The treatments for analysis of the influence of nitrogen fertilization on the hormetic effect consisted of the combination of nitrogen fertilization in succession to application of glyphosate subdoses in the common bean crop. The treatments with the use of bacteria and glyphosate were constituted of the application of glyphosate in different formulations after the application in cover or not of Azospirillum brasilense. Finally, the treatments to evaluate the influence of water on the hormetic effect were given by the application of glyphosate subdoses and irrigation slides on the development, production components and yield of the winter common bean under no-tillage system. For this, the cultivar IPR - 139 of IAPAR was used. It was concluded that there was stimulation of common bean growth with application of subdoses of up to 14.4 g ha-1 of glyphosate, however, the same did not occur in the presence of nitr...

Acne is prevalent amongst youth in Hong Kong and has considerable psychological effects. The application of a TCM approach led to the detection of significant associations between diet and the occurence of acne. TCM-syndrome-tailored dietary manipulation was effective in reducing the clinical severity of acne for patients with imbalance of chong-ren subtype. (Abstract shortened by UMI.) / In (1), 1068 Chinese subjects were sampled from the general health evaluation and eight governmental secondary schools in Hong Kong were assessed for their clinical severity of acne. Over 93% of the subjects had a certain degree of acne and the prevalence of clinical acne was of 40.4% and coexisted with a high frequency of acne disability. Assessment of the clinical severity of acne did not correlate strongly with the effect on QOL (gammas= 0.445, P < 0.001). Multivariate logistic regression showed that female gender (P = 0.002), higher GAGS score (P < 0.001), higher perceived stress (P = 0.01) and willingness to pay Hong Kong $15,000 for a hypothetical permanent cure (P = 0.03) were positive predictors for acne disability. / In (2), 322 university entrants completed a dietary questionnaire capturing 11 categories of food intake and were examined for body constitutions of yin-predominance or yang-predominance with a published TCM diagnostic assessment procedure/method. There were 155 (48.1%) participants in the yin-predominant group and 167 (51.9%) in the yang-predominant group. No association of diet and acne was found when the participants were considered as a whole group. In yin-predominant group, intake of foods from street stalls (P = 0.04) was significantly associated with a lower likelihood of acne occurence. In yang-PG, the intake of desserts (P = 0.04) and fresh fruit juices (P = 0.02) was significantly associated with a higher likelihood of acne occurence, whereas the intake of dairy and soy products (P = 0.04) was significantly associated with a lower likelihood of acne occurence. / In (3), 233 students with clinical acne as assessed by GAGS were diagnosed for his or her TCM syndrome subtype, namely wind-heat subtype, damp-heat subtype, stagnant blood or phlegm subtype, and imbalance of chong-ren subtype. They were then randomly assigned to either intervention group (IG) or control group (CG). There were respectively 60 students belonged to each of the wind-heat, damp-heat, and stagnant blood or phelgm subtypes, and 53 students belonged to imbalanced of chong-ren subtype. With the use of a computer generated randomisation list using blocks of six, 30 (50%) students were assigned to either IG or CG for wind-heat, damp-heat, and stagnant blood or phelgm subtypes accordingly, whilst 26 (49%) and 27 (51%) students were assigned to either IG or CG for imbalance of chongren subtype. TCM-syndrome-tailored diet advice plus standard medical advice were given to IG whilst standard medical advice alone was given to CG over 12-week study period. The primary analysis was to compare the percentage change of GAGS from baseline to 12 weeks between the groups using univariate analysis for each TCM syndrome, controlling for the variation in the dependent variables due to gender, age, BMI, schools, physical exercise, and female contraceptive use. Within the imbalance of chong-ren subtype, there was a significant reduction of acne severity in IG compared with that in CG (-11.8% vs 2.1%; p=0.046), after adjusting for gender, age, body mass index, schools, physical exercise, and female contraceptive use. In the other three subtypes, there were no significant differences of acne severity between IG and CG / This research was composed of three major parts: (1) a cross-sectional study investigating the prevalence of acne and the acne disability amongst adolescents and young adults from August 2006 to March 2008 in Hong Kong; (2) a cross sectional study investigate the diet-acne connection from a traditional Chinese medicine (TCM) perspective performed amongst young adults in August 2006; and (3) a randomised controlled trial on the effectivenss of TCM-syndrome-tailored dietary advice for adolescents implemented between November 2007 and March 2008 in Hong Kong. / Law, Pui Man. / Adviser: Albert Lee. / Source: Dissertation Abstracts International, Volume: 72-04, Section: B, page: . / Thesis (Ph.D.)--Chinese University of Hong Kong, 2010. / Includes bibliographical references (leaves 140-154). / Electronic reproduction.

O uso de reguladores vegetais aliados à adubação nitrogenada tem sido estudado no sentido de incrementar a produtividade e melhorar a qualidade dos grãos de feijão. Assim, o objetivo do trabalho foi estudar doses de nitrogênio e modos de aplicação de reguladores vegetais no desenvolvimento e produtividade do feijoeiro de inverno em sistema plantio direto. O delineamento experimental foi o de blocos casualizados com quatro repetições com os tratamentos dispostos em esquema fatorial 4x4 constituído pela combinação de doses de nitrogênio em cobertura (zero, 40, 80 e 120 kg ha-1) aplicadas no estádio V4 e modos de aplicação de reguladores vegetais (aplicação nas sementes - 5,0 mL kg de sementes-1 durante a operação de tratamento das sementes; aplicação via foliar - aplicação de 0,5 L ha-1 na fase R5; aplicação nas sementes (5,0 mL kg de sementes-1) e via foliar (0,5 L ha-1 na fase R5)) e uma testemunha (sem aplicação de RVs). Os experimentos foram conduzidos sob pivô central, em sistema plantio direto, após a cultura do arroz (2011) e milho (2012) no município de Selvíria (MS), no período de outono-inverno de 2011 e 2012 em um Latossolo Vermelho distrófico álico e de textura argilosa. Conclui-se que os reguladores vegetais, na dose e modos de aplicação estudados, não influenciam na produtividade; e o aumento nas doses de nitrogênio em cobertura proporcionou incremento na produtividade de grãos, até a máxima dose estudada de 120 kg ha-1 / Abstract: The common bean is of great importance in the Brazilian economy and feeding and nitrogen is the taken up nutrient in larger amount. The use of plant growth regulators combined with nitrogen fertilization has been studied in order to increase productivity and improve the quality of the common bean seeds. The objective this study was to evaluate doses of sidedressing nitrogen and application methods of plant growth regulators in the development and yield of winter common bean in no tillage system. A randomized blocks design was used, in a factorial scheme 4x4 with 16 treatments constituted by doses of sidedressing nitrogen (zero, 40, 80 e 120 kg ha-1) applied at V4 stadium and application methods of plant growth regulators (seed application - 5,0 mL kg-1 of seeds at seeds treatment; leaf spray - 0,5 L ha-1 at R5 stadium; application by seeds treatment (5,0 mL kg-1 of seeds) and leaf spray (0,5 L ha-1 at R5 stadium)) and control - without application , in four replications. The study was conducted under center pivot, on tillage system, after rice crop (2011) and corn crop (2012), in Selvíria, Mato Grosso do Sul State, in 2011 and 2012 in fall-winter season, in a dystrophic Haplustox soil. The conclusion: the plant growth regulators, at the dose and application methods studied, not affect common bean yield; and the increasing of the doses of sidedressing nitrogen provided increment in grain yield up to maximum dose of 120 kg ha-1 / Mestre

This paper presents the results of the analysis of 10 years of information 1957-1966 on three phases-- begin, peak and end bloom-- of the purple common lilac (Syringa vulgaris L.) using data recorded at approximately 1,000 locations throughout the Western Region of the United States. The pattern of geographical advance of the various bloom phases is determined by both a manual mapping procedure developed by the author and by standard statistical methods. Manually drawn isophanes for the various elevations for begin bloom phase are based entirely upon the first 5 years of record, 1957-1961. A Zones of Adjustment map to convert the 5-year equal level maps to the 10-year 1957-1966 normal is also manually drawn. Statistical analyses to ascertain the geographical pattern of advance were made for begin bloom phase for the 5-year period and for all three bloom phases for the 10-year period. Both the manual and statistical analyses indicate a very definite pattern of geographical advance of begin bloom phase of the lilac which is characterized by the Early Ridge. Statistical analyses of all three phases indicate a parallel geographical advance of the three phases with average regional time displacement of about 10 days from begin to peak bloom and 10 days between peak and end bloom. Only the eastern third of the Western Region corresponds closely with Hopkins' Bioclimatic Law. A measure of temporal variation of dates of bloom for each of all three phases indicate a parallel geographical advance of the three phases with average regional time displacement of about 10 days from begin to peak bloom and 10 days between peak and end bloom. Only the eastern third of the Western Region corresponds closely with Hopkins' Bioclimatic Law. A measure of temporal variation of dates of bloom for each of the three phases was determined by computing standard deviations for every station having at least 5 years of record. A map was drawn showing the temporal variability of begin bloom phase throughout the Western Region. Medians of standard deviations for stat ions within each state were also determined. Large differences in standard deviation prevail throughout the region with a general tendency for variability to be highest in the southeastern part of the region and lowest in northeastern areas. A comparison is made between the normal dates of occurrence of bloom phases and temperature data throughout the Western Region. This is achieved by comparing isophanal and isothermal charts and by statistical analysis of data at 360 stations where both phenological and temperature records are available. Comparison of isophanal patterns of equal-level isophanal maps and isotherms at given elevations ( or pressure lvels) on given dates indicate very similar patterns; both are characterized by the Early Ridge. Statistical Analyses of mean begin bloom dates and monthly mean maximum and minimum temperatures indicate that about 90 percent of the variance of bloom dates can be accounted for by maximum and minimum temperature measurements.

The post-harvest physiology of sugarbeet (Beta vulgaris) roots was studied during controlled atmosphere (CA) storage at 35° and 50°F. Zero, 3, 6 and 10% carbon dioxide and 5% oxygen concentrations were employed to investigate the most beneficial concentrations of gases. Under the experimental conditions beets were stored successfully for 200 days. The maximum beneficial effects of CA were observed under 6% carbon dioxide and 5% oxygen at 35°F. Regardless of storage temperatures , sucrose retention was highest in the beets stored under CA, compared to conventional refrigeration (CR). Other beneficial effects include less hydrolysis of sucrose to reducing sugars and a decrease in raffinose accumulation. Fungal growth and sprouting were also inhibited significantly, under CA. In the second phase of the studies, investigations were conducted on sugarbeets to study the effects of different levels of nitrogen fertilizer on the optimum CA storage at 40°F. Regardless of the level of nitrogen fertilization, the beets stored under CA demonstrated beneficial effects as described earlier. In addition, respiration, measured on the whole beets, and amino nitrogen content of the beets were lower in the CA-stored beets than those stored under CR. Accumulation of citric acid and succinic acid was significant in the CA-stored beets.

Memoria para optar al título profesional de: Ingeniera Agrónoma / El desarrollo de las hortalizas tipo “baby” se ha incrementado debido a su rápido procesamiento y su atractivo como producto gourmet. A pesar de estos beneficios, las elevadas concentraciones de nitrato en sus tejidos generarían graves problemas a la salud de sus consumidores. Para disminuir estas concentraciones, la dosis de fertilización nitrogenada y la determinación del momento correcto de cosecha son fundamentales. El objetivo del presente trabajo fue evaluar la concentración de nitrato en hojas de dos cultivares de acelga tipo “baby” modificando la concentración de nitrógeno (N) en la solución nutritiva y el horario de cosecha. Para esto, se montaron dos ensayos independientes, donde se midió la concentración de nitrato, la actividad de nitrato reductasa (NR), color y porcentaje de masa seca dos cultivares de acelga (Beta vulgaris L. var. cicla), cv. SCR107 (acelga de pecíolo y nervadura central roja, E1) y el cv. Oriole (acelga de pecíolo y nervadura central anaranjado, E2). Se realizó un diseño aleatorizado de parcelas divididas donde la parcela principal correspondió a la concentración de nitrógeno en la solución nutritiva (100, 200, 300 y 400 mg N Lˉ¹) y las subparcelas a las diferentes horas de cosecha (8:00, 12:00 y 21:00). En E1, la hora de cosecha fue un factor con efecto significativo sobre la concentración de nitrato, siendo mayor en el horario de las 8:00 que en el de las 12:00 y 21:00. Esto probablemente debido a que nitrato reductasa tuvo su mayor actividad durante este periodo. Por otro lado, en E2 el factor concentración de nitrógeno en la solución nutritiva sí tuvo efecto significativo en la concentración de nitrato, además del horario de cosecha, donde las mayores concentraciones generaron una mayor concentración de nitrato en los tejidos. En ambos ensayos se obtuvieron mayores concentraciones de nitrato en el pecíolo y nervadura central que en la lámina, y estas aumentaron a medida que aumentó la edad de la planta. / The development of baby leaf vegetables has increased due to its fast processing and its attractiveness as a gourmet product. Despite these benefits, high nitrate concentrations in vegetal tissues generate serious problems for the health of their consumers. To reduce these concentrations, the rate of nitrogen fertilization and determining the appropriated harvest time is critical. The objective of this study was to evaluate the nitrate concentration in leaves of two baby swiss chard (Beta vulgaris L. var cicla) cultivars by changing the concentration of nitrogen (N) in the nutrient solution and harvest time. In two independent assays, nitrate concentration, activity of nitrate reductase (NR), color and dry matter percentage were measured on SCR107 (red swiss chard, E1) and Oriole (orange swiss chard, E2) cultivars. The assays were ramdomizedin a split plot desing, where the main plot corresponded to the nitrogen concentration in the nutrient solution (100, 200, 300 and 400 mg N Lˉ¹) and subplots to different harvest times (8:00, 12:00 and 21:00). In E1, the harvest time had significantly affected nitrate concentration, being higher 8:00 than 12:00 and 21:00. Probably because the nitrate reductase activity was higher at this period. On the other hand, in E2 the nitrogen concentration in the nutrient solution, combined to harvest time, had significant effect on nitrate concentration in vegetal tissues being higher. In both assays, a higher nitrate concentration in petiole and midrib tissues compared to the leaf blade, and increased in aged leaves.

Calluna vulgaris L.Hull readily colonises arsenate contaminated mine spoil soils in south-west(SW)England.At these sites, it forms mycorrhizal association with the ericoid ascomycete fungus Hymenoscyphus ericae. The initial aim of this study was to investigate the physiological response of H.ericae populations to arsenate.Mine site populations were found to have evolved arsenate resistance in comparison to the heathland population.This research demonstrates the evolution of arsenate resistance through an enhanced arsenite efflux in populations of H.ericae from As contaminated mine spoil soils. H.ericae also confers arsenate resistance to C.vulgaris. The ecological significance of these findings is discussed. / Doctor of Philosophy (PhD)

L'autorisation de mise en culture de plantes transgéniques en Europe est suspendue à l'étude de ses conséquences et de ses moyens de gestion. C'est le cas pour la betterave sucrière tolérante à un herbicide non sélectif. Il existe en effet un risque de flux des transgènes de la culture vers des mauvaises herbes apparentées, les betteraves adventices, fréquentes dans les champs de betterave sucrière. Ce flux permettrait la transmission de la résistance à l'herbicide aux adventices et donc un retour à la situation actuelle, voire à une situation pire si le transgène confère un avantage à l'adventice dans d'autres cultures de la rotation. Pour déterminer les pratiques agricoles propres à éviter ou limiter l'apparition de betteraves mauvaises herbes transgéniques, il faut identifier les éléments des systèmes de culture qui influencent la démographie et la génétique des populations de betterave dans une région et à long terme. <br />À cause des dimensions spatiales et temporelles du flux de gène ainsi que de la large gamme de variabilité des systèmes de culture, il est impossible d'étudier le phénomène exclusivement en expérimentation. Par conséquent, nous avons développé un modèle (GENESYS-BETTERAVE) qui quantifie les effets des systèmes de culture sur ce flux de gènes. Il est centré sur le cycle de développement des betteraves cultivées et adventices dans chaque parcelle basé sur une succession de stades clé (plantules, montées, plantes en fleurs, production semencière, stock semencier). Pour chaque stade est calculée la densité d'individus dans la parcelle ainsi que les proportions génotypiques, principalement celles des individus transgéniques. Les relations entre les stades dépendent des cultures en place dans les parcelles, des techniques utilisées pour gérer ces cultures ainsi que du génotype des betteraves. Pendant la floraison, du pollen est échangé entre les parcelles et l'importance de cette dispersion dépend du parcellaire. Une partie des informations nécessaires à la réalisation du modèle, est tirée de la littérature. <br />Des expérimentations sont ensuite réalisées pour étudier et quantifier les parties encore peu connues du cycle de développement. Elles ont permis de décrire et de modéliser le devenir des semences enfouies de betteraves adventices, en mesurant la mortalité in situ, les capacités de germination des semences et de croissance pré-levée des plantules en fonction des saisons. D'autres essais ont permis de modéliser toutes les étapes clé du développement des betteraves adventices et des traînantes (dynamique et taux de montaison, dynamique de floraison, production de pollen...) dans les cultures les plus fréquentes de la rotation betteravière. <br />Après avoir été programmé sous forme de logiciel, le modèle est alors utilisé pour des simulations simples qui montrent qu'il prend bien en compte les éléments caractéristiques des systèmes de cultures, en attendant une validation pour vérifier à plus grande échelle le réalisme de la prédiction.

Asistimos en la actualidad a una constante pérdida de la diversidad genética de los cultivos. Paralelamente en muchas zonas del mundo, especialmente en los países más desarrollados, se produce una regresión de la agricultura que conlleva problemas medioambientales. Algunas variedades tradicionales han sido seleccionadas históricamente por sus elevadas propiedades gastronómicas lo cual ha ayudado a su persistencia, incluso compitiendo localmente con las variedades mejoradas. Dado que los consumidores de los países desarrollados están dispuestos a pagar precios superiores por la calidad sensorial de los productos, la recuperación de variedades tradicionales organolépticamente destacadas puede ayudar tanto al mantenimiento de la diversidad biológica como a la recuperación de algunas zonas de cultivo. En este contexto la delimitación de Denominaciones de Origen Protegidas (DOPs) y la descripción objetiva de las propiedades de los productos en ellas cultivados, debe considerarse una actividad prioritaria.La Tesis Doctoral que se presenta aborda esta cuestión al estudiar la interacción genotipo x ambiente en variedades tradicionales de judía (Phaseolus vulgaris L.) históricamente cultivadas en Catalunya, referente al contenido de proteína, almidón, amilosa, amilopectina, sacarosa, ácido málico y ácido cítrico en el grano. Se han escogido dichas moléculas porque la bibliografía indica que están relacionadas con atributos sensoriales de la judía una vez cocinada.Para delimitar los efectos genéticos, ambientales y de interacción se efectuaron ensayos de campo en cinco zonas de Catalunya con tradición de cultivo de judía (Garrotxa, Vallès Occidental, Vallès Oriental, Maresme y Baix Llobregat), durante dos años consecutivos. Como germoplasma se emplearon cuatro tipos varietales catalanes (Ganxet, Genoll de Crist, Tavella Brisa y Castellfollit del Boix), y cuatro variedades testigos (Faba, Navy, Canela y White Kidney). Todos los efectos principales (localidad, año y variedad) resultaron significativos para la mayoría de los carácteres. Las máximas diferencias se presentaron entre las localidades de Santa Pau y el Vallès, representativas de condiciones extremas dentro de la variación ambiental que abarca el estudio. El análisis multivariante confirma el alejamiento de la localidad Santa Pau del resto. Suelos volcánicos, elevada capacidad de intercambio catiónico, y cultivo en secano, hacen de esta localidad una peculiaridad interesante con una producción de composición química bien diferenciada.Las variedades tradicionales Ganxet (Montcau) y Genoll de Crist se sitúan en grupos de significación extremos para la mayoría de los compuestos estudiados mientras que los testigos se sitúan habitualmente en grupos de significación intermedios.Se han detectado numerosas interacciones significativas genotipo x localidad lo cual es importante para justificar la elección de determinados tipos varietales en cada zona si pretendemos maximizar o minimizar alguno de los componentes químicos. A menudo las interacciones más significativas coinciden con combinaciones consolidadas históricamente de variedad x ambiente y que tienen ya prestigio (p.e. Ganxet en el Vallès y Maresme; Genoll de Crist en el Maresme, Navy y Tavella Brisa en Santa Pau). De confirmarse también en el ámbito sensorial este abanico de características químicas causado por efectos genéticos, ambientales y de interacción, la definición objetiva de al menos dos denominaciones de origen en Catalunya parece una tarea posible y que merece impulsarse. Además, todo parece indicar, que este enfoque podría utilizarse de manera general para la delimitación de DOPs en judía. / We attended at the present time a constant loss of the genetic diversity of the cultures. Parallelly in many zones of the world, specially in the developed countries, a regression of the agriculture takes place that entails environmental problems. Some traditional varieties have been selected historically by their high gastronomical properties which has helped its persistence, even competing locally with the improved varieties. Since the consumers of the developed countries are arranged to pay superior prices by the sensorial quality of products, the recovery of outstand ing traditional varieties can help the maintenance of the biological diversity as to the recovery of some zones of culture as much. Against this background the boundary of Protected Denominations of Origin (DOPs) and the objective description of the properties of products in cultivated them, is an activity that must be considered high-priority.The Doctoral Thesis that appears approaches this question when studying the interaction genotype x environment in traditional varieties of bean (Phaseolus vulgaris L.) historically cultivated in Catalunya, referring to the content of protein, starch, amylose, amylopectin, sucrose, malic acid and citric acid in the grain. These molecules have been chosen because the bibliography indicates that they are related to sensorial attributes of the bean once cooked.In order to delimit the genetic, environmental effects and of interaction tests of field in five zones of Catalunya with tradition of bean culture took place (Garrotxa, Vallès Oriental, Vallès Occidental, Maresme and Baix Llobregat), during two consecutive years (2002, 2003). As germoplasma four Catalan varietales types were used (Ganxet, Genoll de Crist, Tavella Brisa and Castellfollit del Boix), and four varieties witnesses (Faba, Navy, Canela and White Kidney).All the main effects (locality, year and variety) were significant stops for most of the characters. The maximum differences appeared between the localities of Santa Pau and the Vallès, representative of extreme conditions within the environmental variation that includes the study. The multivariant analysis confirms the distance of the locality Santa Pau of the rest. Volcanic grounds, high capacity of cationic interchange, and culture in dry land, makes of this locality an interesting peculiarity with a production of a differentiated chemical composition. The traditional varieties Ganxet (Montcau) and Genoll de Crist are located in extreme groups of meaning for most of the studied compounds whereas the witnesses locate themselves habitually in intermediate groups of meaning. Numerous significant interactions genotype x locality have been detected which is important to justify the election of certain varietal types in each zone if we try to maximize or to diminish some of the chemical components. Often the most significant interactions agree with consolidated combinations historically of variety x environment and that have prestige already (e.g. Ganxet in the Vallès and Maresme; Genoll de Crist in the Maresme, Navy and Tavella Brisa in Santa Pau). If also in the sensorial scope this fan of chemical characteristics caused by genetic, environmental effects and of interaction is confirmed, the objective definition of at least two denominations of origin in Catalunya it seems a possible task and that it deserves to impel itself. In addition, everything seems to indicate, that this approach could be used of general way for the boundary of DOPs in bean.
