This experiment was established in January 2000 in a block of 'Washington' navel orange trees at Verde Growers, Stanfield, AZ. Treatments included: normal grower practice, winter low biuret (LB) urea application, summer LB urea application, winter LB urea application plus winter and spring potassium phosphite, winter LB urea application plus summer potassium phosphite, and normal grower practice plus spring potassium phosphite. Each treatment was applied to approximately four acres of trees. For 2000-01, yields ranged from 40 to 45 lbs. per tree, and there was no effect of treatments upon total yield. There was a slight effect upon fruit size and grade. Trees subject to summer LB urea application had significantly more fruit of size 56, compared to trees subject to winter LB urea, and untreated, and untreated trees had significantly more fruit of size 88 than did treated trees. Also, treated trees had slightly more fruit in the fancy grade than did untreated trees.

This thesis focuses on a clientele who currently lives with both a lower life expectancy and a lower quality of life due to obesity. The goal of this thesis is to identify and validate effective interventions for people living in a family environment with intellectual disabilities or treated with antipsychotic medication. Methods. Covering a period of five years, this research includes two studies, each lasting two years, evaluating two interventions. The first is a control-group study involving 82 participants. It assesses the effectiveness of interventions aimed at patient self-control and identifies lifestyle factors related to obesity in this population. The second study includes 7 families (comprised of 36 individuals) and 30 public health care professionals. It assesses the effectiveness of interventions, this time targeting the offer of food by the cooks and the support of public health care professionals. Measures : Body mass index (BMI), waist circumference (WC), antipsychotic medication use, family, lifestyle factors (physical activity, consumption of fruits and vegetables, smoking, duration of sleep), survey of food offer and physiological parameters (blood pressure, fasting glucose and lipid). Results. The WC is a more sensitive measure than BMI to detect obesity, particularly in women, who have a higher incidence of abdominal obesity. The family is a determining variable of the variation in the incidence of obesity. The practice of physical activity and the daily consumption of vegetables (excluding potatoes) are associated with less obesity. Interventions aimed at self-control are ineffective with this population. However, interventions aimed at the cooks and the health care professionals are significantly effective in reducing BMI as well as WC and in increasing the frequency of physical activity and consumption of fruits and vegetables, while improving the quality of the food offered. These improvements are maintained after two years. Conclusion. It appears that interventions specifically targeting the cook and involving the health care professionals are an efficient way to help this clientele.This thesis also highlights the usefulness for health care professionals to change from an intervention model of being the"expert", previously used primarily with an institutionalized clientele, to a model of"non-expert" focusing on collaboration, best suited for interventions on lifestyle factors in family environments.

Master of Public Health / Department of Human Ecology / Tandalayo Kidd / The objectives of the study were to assess fruit and vegetable intake of 6th to 8th grade youth in low-income areas, assess their food environment, and determine factors that influenced fruit and vegetable consumption. Sixth to eighth grade youth from two low-income communities in each of the three states of South Dakota, Kansas and Ohio were involved in the study. Fruit and vegetable intake was measured using the National Cancer Institute (NCI) fruit and vegetable screener tool. The food environment was measured using the Nutrition Environment Measures Survey for Restaurants (NEMS-R) and the Nutrition Environment Measures Survey for Stores (NEMS-S) tools. A generalized linear mixed model in PROC GLIMMIX was used to assess possible predictors of fruit and vegetable intake. Average daily fruit and vegetable consumption for males and females was 3.8 cups (95%CI= 2.4-6.0) and 3.1 cups (95%CI=2.0-4.9) respectively. Grade, gender, ethnicity, community, and state of residence did not influence fruit and vegetable consumption, while fruit and vegetable availability at home influenced intake. Youth had a favorable view of their food environment, contrary to the findings of objective measures.

Objetivos: Investigar as diferenças entre os fatores associados ao consumo de frutas e de hortaliças entre os adolescentes brasileiros. Método: Os dados do consumo de frutas e de hortaliças foram obtidos do banco de microdados sobre consumo alimentar da Pesquisa de Orçamentos Familiares 2008/2009 do IBGE. Foram utilizados os fatores de expansão para a obtenção de representatividade nacional e estimar um modelo, por meio da regressão Tobit ajustada por sexo, idade, raça/cor, IMC, escolaridade do chefe da família, zona residencial, região, renda per capita, preço de frutas e de hortaliças para identificar os fatores associados ao consumo de frutas e de hortaliças. Para a construção do modelo, adotou-se o método de stepwise forward p<0,20 e nível de significância de 5% para a significância conjunta e das variáveis independentes. Foi utilizado o Programa STATA versão 14. Não foi incluído o consumo de frutas e de hortaliças presentes nos alimentos preparados. Resultados: Foram analisados o consumo de frutas e de hortaliças de 7.613 adolescentes. Mais de 47,61% dos adolescentes não consumiram frutas e hortaliças nos dias avaliados; 3,20% consumiram a quantidade de frutas e hortaliças dentro do recomendado de 440g/dia. Os fatores associados do consumo de frutas foram sexo, IMC, a zona residencial e a renda per capita e; os fatores associados ao consumo de hortaliças foram região, renda per capita e preço implícito de hortaliças. A renda per capita foi o único fator associado comum ao consumo de frutas e de hortaliças, porém com diferentes efeitos marginais. Conclusões: A maioria dos adolescentes brasileiros não consome a quantidade de frutas e hortaliças recomendada. Os fatores associados ao consumo de frutas são diferentes dos fatores associados ao consumo de hortaliças. / Objective: To investigate the differences between the factors associated to the consumption of fruits and of vegetables among Brazilian adolescents. Methods: Data were obtained from the IBGE 2008/2009 Household Budget Survey. To identify the factors associated with fruit and vegetable consumption it was used Tobit regression adjusted for sex, age, race/color, BMI, household educational level, residential area, region, per capita income, implicit fruit price and implicit vegetable price. For the construction of the model, we adopted the stepwise forward method p<0.20 and significance level of 5% for the joint significance and the independent variables. The STATA version 14 program was used. The consumption of fruits and vegetables present in prepared foods was not included. Results: The fruit and vegetable consumption of 7,613 adolescents were analyzed. More than 47,6% of the adolescents did not consume any fruit and vegetable; 3.20% consumed the amount of fruits and vegetables within the recommended. The associated factors of fruit consumption were BMI, residential area and per capita income; The factors associated with the consumption of vegetables were region, per capita income and implicit vegetable price. Per capita income was the only common factor associated with the consumption of fruits and vegetables, but with different marginal effects. Conclusion: Most Brazilian adolescents do not consume the recommended amount of fruits and vegetables. The factors associated with fruit consumption are different from the factors associated with the consumption of vegetables.

Introdução- O conceito de biodiversidade para alimentação e agricultura inclui um conjunto de componentes, como variedade de alimentos, nível de recursos genéticos e gestão dos sistemas de produção dos diversos cultivos. Segundo a FAO (Food and Agriculture Organization of the United Nations), estudar e entender a biodiversidade é essencial para garantir a segurança alimentar e o desenvolvimento sustentável. Objetivos- Caracterizar a diversidade e disponibilidade de frutas e hortaliças frutosas para a população do município de São Paulo e verificar a disponibilidade de informação nutricional dos diferentes grupos de mercado. Métodos- Foram selecionadas as cinco frutas e hortaliças frutosas mais adquiridas (kg per capita/ano) segundo a POF (Pesquisa de Orçamentos Familiares) 2008-2009 que apresentam ao menos três grupos de mercado comercializados na CEAGESP (Companhia de Entrepostos e Armazéns Gerais de São Paulo): Banana (Musa spp.), Laranja (C. sinensis L. Osbeck), Maçã (M. domestica Borkh.), Mamão (C. papaya L.), Abacaxi (A. comosus L.), Tomate (L. esculentum Mill.), Abóbora (Cucurbita spp.), Pimentão (C. annuum L.), Pepino (C. sativus L.), Berinjela (S. melongena L.). A presença dos grupos de mercado de cada espécie foi avaliada em estabelecimentos de comercialização de alimentos localizados em 18 distritos do município de São Paulo classificados por tercis de IDH. Foram avaliados um total de 73 estabelecimentos (18 feiras livres e 55 mercados, supermercados e hipermercados) em duas épocas distintas (julho-setembro de 2014 e fevereiro-março de 2015). A busca de dados de composição nutricional foi realizada nas principais bases de dados (Scielo, Lilacs, Bireme) e em dados publicados por organizações nacionais e internacionais (EMBRAPA, FAO, INFOODS), além das tabelas nacionais TACO, TBCAUSP e Fontes Brasileiras de Carotenoides. As informações nutricionais de macro e micronutrientes foram compiladas em uma única tabela. Resultados- Estabelecimentos localizados em distritos de alto Índice de Desenvolvimento Humano (IDH) apresentaram maior diversidade para as espécies banana, mamão, maçã, tomate, pepino e pimentão em comparação aos distritos de médio IDH (p<0,05) em 2014. Em contrapartida, os distritos de alto e baixo IDH ofertaram quantidades semelhantes de grupos de mercado para as espécies estudadas, exceto o mamão e tomate que estiveram mais presentes no alto IDH. Em relação às frutas, a Banana Nanica, Banana Prata, Laranja Pera, Maçã Gala e Abacaxi Pérola estiveram presentes em quase 100 por cento dos estabelecimentos, nos três IDHs. Já em relação às hortaliças frutosas, o Pimentão Verde e Berinjela Comum estiveram presentes em quase 100 por cento dos estabelecimentos avaliados em 2014. Conclusões- Observaram-se diferenças de disponibilidade de grupos de mercado das espécies estudadas, conforme classificação do IDH do distrito. Verificou-se que as feiras livres mostraram ser melhores locais de escolha de compra pelos consumidores, já que de maneira geral, apresentaram maior diversidade, a preços inferiores aos praticados nos supermercados. Apesar das escassas informações nutricionais disponíveis na literatura, foi possível evidenciar as diferenças de concentração de certos nutrientes para diferentes grupos de mercado estudados. Dessa forma, acredita-se que a disseminação dessas informações pode ser benéfica para os consumidores realizarem escolhas de consumo mais inteligentes, aumentando a diversidade de nutrientes na dieta. / Introduction- The concept of biodiversity for food and agriculture includes a set of components such as varieties of food, level of genetic resources and management systems used in culturally diverse populations. Understanding local food biodiversity is essential to ensure food security and sustainable development. Objective- To characterize the diversity and availability of fruits and vegetables in the Sao Paulo municipality and verify the availability of nutritional information of different market groups. Methods- the market-groups targeted in this study belong to the five most commonly purchased fruits and vegetables in São Paulo, according to the Brazilian Household Budget Survey (2008-2009): banana (Musa spp.), orange (C. sinensis L. Osbeck), apple (M. domestica Borkh.), papaya (C. papaya L.), pineapple (A. comosus L.), tomato (L. esculentum Mill.), pumpkin (Cucurbita spp.) , bellpepper (C. annuum L.), cucumber (C. sativus L.), eggplant (S. melongena L.). The representation of each market group was evaluated by checking the retail trades from 18 districts classified by tertiles (HDI). A total of 73 retailers were evaluated (18 street markets and 55 markets and supermarkets) in two different seasons (July-September 2014 and February-March 2015). To perform data collection of micro and macronutrients, terms were used, including the nutritional composition, biodiversity, variety, cultivar, in various combinations, with emphasis on recently published data in databases composition of conventional foods, scientific articles, data published by national and international organizations and agencies related. Nutritional information were compiled into a single table. Results- Retailers located in high districts Human Development Index (HDI) showed greater diversity for species banana, papaya, apple, tomato, cucumber and bellpeppers compared to the average HDI districts (p <0.05) in 2014. However, high and low HDI districts offered similar amounts of market groups for the species studied, except papaya and tomatoes that were more frequently found in high HDI. For fruit, Banana Nanica, Banana Prata, Orange Pera, Apple Gala and Pineapple Pérola were present in almost 100 per cent of the establishments in the three tertile. In relation to fruit vegetables, the Bellpepper Verde and Eggplant Comum were present in almost 100 per cent of retailers evaluated in 2014. Conclusions- Differences in the availability of market groups from the species studied were observed, according to the district HDI ranking. It was found that streets markets have proven to be better places in choice of purchase by consumers, since in general, had higher diversity at lower prices than in supermarkets. Despite the meager nutritional information available in the literature, differences in concentration of certain nutrients to different market groups studied were observed. Thus, it is believed that the dissemination of such information can be beneficial for consumers make more intelligent consumer choices, increasing the diversity of nutrients in the diet.

La taille du fruit est un caractère agronomique important pour le rendement des espèces cultivées.Or, excepté chez la tomate, les mécanismes impliqués dans la variation de la taille des fruits charnus sont encore mal connus. L'objectif de ma thèse était d'identifier les principaux facteurs anatomiques impliqués dans la variation de la taille des baies, de réaliser des tests d'association génétique sur des gènes candidats et de rechercher des possibles traces de domestication liées à la variation de la taille des baies. Le nombre de cellules déjà déterminé dans l’ovaire avant l’anthèse et la capacité des cellules du mésocarpe à grossir après l’anthèse se sont révélés les principaux déterminants de la variation de la baie entre les variétés. Trois gènes potentiellement impliqués dans ce caractère ont été identifiés par des approches de génétique d'association. La MADS boxVvAGL11 est associée au nombre de pépins de la baie. VvHMGR1, une HMGR impliquée dans la synthèse des isoprénoïdes précurseurs de régulateurs de croissance, est associée à la longueur des baies. Enfin, VvJMJ un facteur de transcription de type jumonji est à la fois associé à la variation du poids et à la longueur des baies. La caractérisation du locus Fleshless berry (Flb) a également été poursuivie avec (i) l’analyse du polymorphisme de séquence de 69 fragments de gènes entre les vignes sauvages et cultivées, ce qui a permis l’identification d’un gène présentant une trace de sélection et une diversité nucléotidique plus élevée dans le compartiment sauvage que dans lecultivé. (ii) La mise en évidence d’une homozygotie complète d’une région de 1 Mb contenant le locus Flb chez certains cultivars comme l’Ugni Blanc, rendant impossible le clonage positionnel du gène dans la population F1. L’ensemble de ce travail a permis de mettre en évidence la complexité des mécanismes à l’origine de la variation de la taille de la baie chez la vigne. Nous avons montré la faisabilité des études de génétique d’association chez la vigne en utilisant des gènes candidats pour le poids de baies, et identifié les candidats les plus intéressants pour la sélection assistée par marqueurs et les études fonctionnelles ultérieures. / Fruit size is an important trait in fruit crops. However, excepted in tomato, little is known about the genetic and molecular control of fleshy fruit size variation. The aim of my thesis was to identify themain anatomical factors underlying berry size variation, to carry out an association genetics based approach with candidate genes and to search for possible signatures of domestication linked toberry size variation. Cell divisions before anthesis and cell expansion after anthesis were found tobe the major determinants of flesh weight variation between varieties in grapevine. Three geneswere identified by association genetics approaches. The VvAGL11 MADS box was found associated only with the seed number per berry. VvHMGR1, a putative HMGR involved in the synthesis of isoprenoid, a precursor of plant growth regulators, was found associated with berry length. Finally,VvJMJ encoding a putative transcription factor jumonji was associated both with berry weight andberry length variation. The characterization of the Fleshless berry locus (Flb) was also pursued with(i) the analysis of the sequence polymorphism of 69 regions between wild and cultivated grapevines,that leaded to the identification of one gene showing a trace of selection and a higher nucleotide diversity in the wild compartment than in the cultivated compartment. (ii) The discovery of acomplete homozygosity of a 1 Mb region containing the Flb locus in some cultivars such as theUgni Blanc, making impossible the fine mapping of the Flb locus in a F1 population. This study has highlighted the complexity of the mechanisms underlying the berry size variation in grapevines. We demonstrated the feasibility to screen in grapevine by association genetics candidate genes for berryweight and to select the most interesting ones for marker-assisted selection and for furtherfunctional studies.

Orientador: Regina Marta Evangelista / Banca: Giuseppina Pace Pereira Lima / Banca: Luciana Manoel de Oliveira / Resumo: O objetivo desse trabalho foi avaliar o efeito de diferentes tratamentos químicos e de embalagens na conservação pós-colheita de carambolas refrigeradas. Foram utilizados frutos inteiros que após os tratamentos foram acondicionados em bandejas de poliestireno expandido, armazenados à temperatura de 10 ± 1°C e umidade relativa de 90 ± 2 % durante 21 dias. As análises foram realizadas com intervalo de 7 dias em relação aos seguintes parâmetros: cor, perda de massa fresca, firmeza, pH, acidez titulável, sólidos solúveis, açúcares redutores, teor de ácido ascórbico, fenóis e atividade respiratória. No primeiro experimento: Os frutos foram submetidos aos seguintes tratamentos: controle (T1), ácido ascórbico 1% (T2), ácido ascórbico 3% (T3), cloreto de cálcio a 1% (T4), cloreto de cálcio a 3% (T5), EDTA de cálcio a 1% (T6), EDTA de cálcio a 3% (T7). A partir dos resultados obtidos no primeiro experimento foi montado o segundo, associando a melhor concentração de cada tratamento com diferentes tipos de filmes plásticos. Os tratamentos foram: controle (sem filme, sem tratamento) (T1), policloreto de vinila (PVC) + ácido ascórbico a 3% (T2), PVC + cloreto de cálcio a 3% (T3), PVC + EDTA de cálcio a 3% (T4), polietileno de baixa densidade (PEBD) de 0,6 μ + ácido ascórbico a 3% (T5), PEBD de 0,6 μ + cloreto de cálcio a 3% (T6), PEBD de 0,6 μ + EDTA de cálcio a 3% (T7). Os diferentes tratamentos químicos na concentração de 3% e o uso de embalagens de PVC (Policloreto de vinila) e PEBD (Polietileno de baixa densidade) 0,6μ propiciaram melhor conservação de frutos de carambola sem interferir nas características de qualidade / Abstract: The aim of this study was to evaluate the effect of different chemical treatments and packaging on postharvest storage of refrigerated carambole. Whole fruits after the treatments were placed in polystyrene trays, stored at 10 ± 1 ° C and relative humidity of 90 ± 2% for 21 days. Analyses were performed with an interval of 7 days on the following parameters: color, weight loss, firmness, pH, titratable acidity, soluble solids, reducing sugars, ascorbic acid, phenols and respiratory activity. In the first experiment, fruits were submitted to the following treatments: control (T1), ascorbic acid 1% (T2), ascorbic acid 3% (T3), calcium chloride 1% (T4), calcium chloride 3% (T5), calcium EDTA 1% (T6), and calcium EDTA 3% (T7). From the results obtained in the first experiment was established the second, combining the best concentration of each treatment with different types of plastic films. The treatments were: control (no film, no treatment) (T1), polyvinyl chloride (PVC) + ascorbic acid 3% (T2), PVC + calcium chloride 3% (T3), PVC + calcium EDTA 3% (T4), 0.6 μ low density polyethylene (LDPE) +ascorbic acid 3% (T5), 0.6 μ LDPE + calcium chloride 3% (T6), and 0.6 μ LDPE + calcium EDTA 3% (T7). The different chemical treatments on the concentration of 3% and the use of PVC (polyvinyl chloride) and LDPE (Low density polyethylene) 0.6 μ packaging provided better preservation of carambole fruits without interfering in the quality characteristics / Mestre

O Sistema Agroindustrial (SAG) das frutas é um dos mais importantes do Brasil. Ele envolve os segmentos frutas frescas, frutas secas, frutas congeladas, como também seus subprodutos: polpas, sucos, geleias, entre outros. Estima-se que a movimentação financeira na cadeia das frutas foi cerca de 5,8 bilhões de dólares anualmente com frutas frescas, atingindo um patamar de 12,2 bilhões de dólares, incluindo castanhas, nozes e produtos processados (IBRAF, 2010). No que tange à importância socioeconômica do setor, vale considerar o seu grande potencial empregador e de geração de renda. Atualmente a fruticultura brasileira oferece cinco milhões de postos de trabalho, ou seja, 2,8% dos brasileiros trabalham na fruticultura (IBRAF/IBGE, 2010). Contudo, no que se refere à exportação de frutas e derivados, se forem considerados os volumes exportados para a maioria das frutas, excluindo a laranja, quando analisado o coeficiente de exportação sobre a produção, raramente resultam valores acima de 3%. Assim, mesmo com números que parecem ser expressivos para algumas frutas, o país ainda é marginal no comércio mundial de frutas frescas, pois participa em apenas 0,5% do comércio internacional. São poucas as frutas cuja exportação é representativa em relação à produção. Diante desses entraves para a internacionalização do setor, o objetivo do estudo é propor um planejamento estratégico que possa ser aplicado na fruticultura brasileira, de modo a ampliar a competitividade do setor no mercado internacional. A pesquisa realizada tem caráter qualitativo exploratório, utilizando o método Gesis Gestão de sistemas agroindustriais. Para isso, foram realizadas entrevistas com base em um roteiro semiestruturado. A análise dos resultados foi feita por meio da análise de conteúdo das entrevistas, bem como pelo cruzamento dos resultados obtidos com a teoria estudada. Espera-se, como resultado da pesquisa, poder identificar as principais necessidades, barreiras e fatores críticos de sucesso pelos diferentes portes de empresas. / Agroindustrial System (SAG) of fruit is one of the most important in Brazil. The agribusiness system involves the segments of fruit, fresh fruit, dried fruit, frozen fruit as well as its by products: fruit pulps, juices, jams and others. It is estimated that the financial transactions in the chain of fruit was about 5.8 billion dollars annually on fresh fruits, reaching a level of 12.2 billion dollars including nuts, nuts and processed products (IBRAF, 2010). Regarding the socioeconomic importance of the sector, it is important to consider is the potential employer and income generation. Currently, the brazilian fruit offers five million jobs, or 2.8% of brazilians working in the fruit (IBRAF/IBGE, 2010). However as regards the export of fruit and their products, if we consider the export volumes for most fruits, excluding oranges, when analyzing the coefficient on export production, rarely result in values above 3%. Thus, even with numbers that seem to be significant for some fruit, the country is still marginal in world trade in fresh fruits, as participates in only 0.5% of international trade. There are few fruits whose export is representative in terms of production. Given these barriers to the internationalization of the sector, the objective of the study is to propose a strategic plan that can be applied in the Brazilian fruit trees in order to expand the sector\'s competitiveness in the international market. The survey is a qualitative exploratory, using the method Gesis Management of agribusiness systems. To this was based on interviews with a semi-structured. The analysis of the results was done by content analysis of interviews as well as by merging results from the theory studied. It is expected as a result of the research to identify the main needs, barriers and critical success factors for different sizes of companies.
