Results of the 1995 National Cooperative Dry Bean Nursery Trials are reported in this paper. Thirty seven varieties of eight different classes of beans were included in this replicated, small plot trial. Bill-Z, the leading pinto bean variety in the area, was the highest yielding variety in the study with a yield just under 3000 pounds per acre. Fleetwood Navy variety and UI 59 Great Northern variety were the next leading varieties with yields about 50 pounds less than Bill-Z. Chase, a pinto variety recently developed with strong rust tolerance, yielded only 2300 pounds per acre in this study. Yields, seed per pound, aerial biomass, harvest index and maturity class are also reported.

Fungicidal evaluations were performed on pinto beans in two sites in 1994 and one site in 1995 to determine their effect on bean rust, white mold or common bacterial blight The results were mixed between sites and years, but in 1994 the untreated control yielded less than all of the treatments except one and the Fluazinam 500F 1 lb rate was the highest yielding treatment In 1995, no disease symptoms were observed in the field.

Lygus lineolaris (Palisot de Beauvois), L. elisus (Van Duzee), L. borealis (Knight) and Adelphocoris lineolatus (Goeze) were the major species of plant bugs present in commercial field bean and soybean fields in 2008–2010. Lygus lineolaris comprised 78–95% of the mirid adults and <10% were A. lineolatus. Lygus lineolaris reproduced in field beans and completed a single generation. In field beans, adults entered the crop in late July, corresponding to growth stages from late vegetative to pod initiation, and females laid eggs in the crop. Nymphs hatched and developed and were most numerous at the seed development and seed filling stage. At seed maturity, late instar nymphs and adults were present. In soybeans, L. lineolaris reproduced but nymphs had poorer survival than in field beans. Late in the season, adult numbers greatly increased in field beans and soybeans, partly due to immigration of adult Lygus bugs from early‐maturing crops. Field beans and soybeans appeared to be a transient host for A. lineolatus. There were no effects on yield quality or quantity associated with the numbers of plant bugs seen in field surveys. In laboratory and field cages, the type of injury from L. lineolaris feeding differed among plant growth stages but not between nymphs and adults, although nymphs generally were more injurious. At flowering to pod initiation, abortion of buds, flowers or pods was the most common response to feeding injury; pod abortion did not occur when injury occurred at later growth stages. Sometimes abortions resulted in reduced yield quantity, but sometimes plants compensated for the injury. No loss of seed quality occurred from feeding at this stage. During seed development and filling, feeding injury most frequently affected the vascular supply to filling seeds, resulting in shriveled seeds and pods at harvest, and consequent reduced total harvested seed weight. At seed maturity, direct seed injury, involving penetration of the testa and loss of cotyledon tissue, was the most frequent injury and resulted in pits in the seed coat at harvest. There was no loss in yield quantity when feeding occurred at seed maturity, but seed pitting reduced yield quality. / May 2016

This study examines Haudenosaunee foodways in the Great Lakes Region between the early seventeenth century and the mid to late eighteenth century. The study is divided into two parts. First, the Creation Story is explored as it transmits the origin of the Three Sisters, a cropping system of inter-planted corn, beans and squash. The teachings of the Three Sisters highlights the importance of polyculture and sustainability. Conversely, a Westerners’ scientific account of how the Three Sisters came to be farmed together is studied. The independent pathways of the corn, beans and squash is examined as they arrived in New York State from the Mexico highlands. Recent findings show the Three Sisters were adopted independently in eastern North America beginning around A.D. 1300. They were grown together in some locations on a regular basis. The adoption of the polycultural complex of the Three Sisters was gradual and took place approximately 700 years ago as each of the crops adjusted to the climate and new surroundings. Secondly, the relationship between food, specifically the Three Sisters and acculturative change are examined pre-and-post contact. Acculturative change occurs when two independent cultures comes into contact with one another. The degree of influence is not equal as one culture can be absorbed, shaped or influenced more strongly by the other culture. The Haudenosaunee culture underwent acculturative change because the fur trade economy affected their foodways due to the influx of European goods such as the brass kettle and encroachment on their land and hunting grounds. The Haudenosaunee retained the core of their cultural beliefs and cultural practices because they made decisions, specifically their selection of goods and agricultural practices, as an extension of their cultural beliefs. Acculturative change resulted in a more monocropped and creolized agricultural system, usage of draft animals, fruit orchards and the plow. This study lies at the intersection of ethnohistory and food history. This study will serve as a tool to analyze and understand Haudenosaunee historical experiences from a First Nations cultural perspective. / Graduate / 2017-08-21

O experimento foi conduzido na UNESP/FCAV no Departamento de Fitossanidade, Laboratório de Resistência de Plantas a Insetos, em sala climatizada à temperatura de 25 ± 1ºC, umidade relativa de 70% ± 10% e fotofase de 12h. Foi avaliada a antibiose de genótipos de feijoeiro a Z. subfasciatus, utilizando delineamento inteiramente casualizado com 43 genótipos e 40 grãos (repetições). Os grãos foram acondicionados em recipientes cilíndricos de plástico sendo liberados 10 casais de Z. subfasciatus por amostras para ovipositarem nos grãos. Diariamente, foi observada a quantidade de ovos em cada grão, a fim de se obter dois ovos por repetição. Os grãos com dois ovos foram individualizados, pesados e colocados em um "eppendorf" de dois mL durante 10 dias para verificação diária da eclosão das larvas. Após 25 dias da oviposição os grãos continuaram a ser observados diariamente, para a quantificação dos adultos emergidos, os quais foram sexados e confinados isoladamente em "eppendorf" de dois mL para avaliação do peso e longevidade. Ao término da emergência dos adultos os grãos foram pesados novamente e depois foram secos em estufa para a determinação da massa seca consumida. Os resultados foram submetidos às análises uni e multivariada para a determinação dos níveis de resistência. A partir desse primeiro ensaio selecionou-se oito genótipos com características de resistência e dois suscetíveis no intuito de validar o teste anterior e determinar as categorias de resistências e possíveis causas. Para tanto foram realizados testes com e sem chance de escolhas, ambos em delineamento inteiramente casualizado com os 10 genótipos ... / Abstract: The aim of this work was to select bean genotypes with resistance-related traits against Zabrotes subfasciatus (Boheman, 1833) (Coleoptera: Bruchidae) to identify resistance categories, levels and mechanisms. The experiment was carried out at UNESP/FCAV, in the Departamento de Fitossanidade, Laboratório de Resistência de Plantas a Insetos, at 25 ± 1 ºC temperature, 70 ± 10% relative humidity and 12h photophase. Was evaluated antibiosis of bean genotypes to Z. subfasciatus, using completely randomized design with 43 genotypes and 40 seeds (replicates). The seeds were placed in cylindrical plastic containers in which 10 pairs of Z. subfasciatus were released per sample to lay eggs in the seeds. The amount of eggs in each seed was recorded daily in order to obtain two eggs per replicate. Seeds with two eggs were individualized, weighed and kept in 2 mL eppendorf for 10 days to check the eclosion of the larvae daily. At the end of the emergence of the adults the seeds were weighed again and then were dried in an oven to determine the dry weight consumed. Results were subjected to univariate and multivariate analyses to determine the levels of resistance. From this first assay, eight genotypes with resistance-related traits and two susceptible genotypes were screened to validate the prior test and determine the resistance categories and potential mechanisms. For this, free-choice and no-choice tests were performed, both in a completely randomized design with 10 screened genotypes and four replications. In the first test, arenas made of aluminum circular trays were used, which supported circular styrofoam plates with openings on the edges where cylindrical plastic containers with 10 g of seeds of the respective genotypes were inserted equidistantly from the center of the plate. Next, seven pairs of Z. subfasciatus per genotype were released on the center of the plate to evaluate attractiveness ... / Mestre

Não consta resumo na publicação / Biological and immunological properties of phytohemagglutins from two brazilian varieties of beans (Phaseolus vulgaris) were studied. Through immunoprecipitation in agar gel, immuoenzymatic assays (ELISA) and eletrophoretic behavior after affinity chromatography purification it was shown that the lectins are similar. Both lectins when given to rats are toxic. They reduce growth and intestinal dissacharidase activity. They also able to smooth the \"microvillous\" of the enterocyte and to induce the appearance of autophagosomes in the enterocyte citoplasm. All this modification result in a reduced rate of carbohydrates absorption either in \"vitro\" or \"in vivo\".

O presente trabalho experimental focaliza o tema \"compostos fenólicos no café\". Dentre estes compostos se destacam os flavonóides, os ácidos clorogênico, cafêico, cafeilquinico, e seus isômeros. Na pesquisa foram avaliados quantitativamente, por espectrofotometria UV/VIS, as espécies fenólicas presentes após extração e complexação em amostras de cafés (cascas e sementes) com grãos em vários estágios de maturação. Foram obtidos valores na faixa de 10-6 mol.L-1 para fenóis totais nas cascas e nos grãos. O método de extração aqui proposto tornou-se bastante viável, sendo possível sua aplicação com tempo de preparo de amostras secas para análise de cerca de 40 minutos. As evidências experimentais decorrentes dessa pesquisa sugerem que tais espécies fenólicas (anti-oxidantes) podem ser aproveitadas de um material que é descartado (a casca do café), sendo, portanto um grande benefício econômico para a sustentabilidade do cultivo do café. / This experimental work has focused the theme \"Phelonic Compound in Coffee Beans\". Among these compounds have been shown flavonoids species, chlorogenic acid, caffeic acid, caffeinic acid and their isomer. The phelonic species has presented after extraction and complexation from coffee samples (peels and beans) using coffee beans in different grown and developed process has been evaluated in quantitative research by using UV/VIS Spectrophotometry Values have been got about 10-6 mol.L-1 in peels and beans. The proposed extraction method has been not only viable but its use possible with preparing time of dried samples for analyses in about 40 minutes. The experimental evidence resulting from this research has proposed that such phenolic antioxidant species can be made a good use of discarded material (the peel of coffee beans) therefore a great economical benefit for sustainable coffee cultivation.

O feijão é um importante alimento na dieta alimentar do brasileiro. A cada colheita ocorrem perdas dos grãos de feijão devido ao ataque de insetos e roedores. Uma das maneiras de se preservar os grãos de feijão, mantendo suas características nutricionais, é o uso da radiação gama. O objetivo do trabalho é avaliar os efeitos de diferentes doses da radiação gama nas propriedades físico-químicas do feijão carioca submetido à cocção e que sofreu ou não o processo de maceração. Partes dos feijões cariocas crus foram utilizadas como controle e outra parte foram submetidos à radiação ionizante com doses de 1, 5 e 10 kGy. Após a irradiação uma parcela das amostras (controle e irradiadas) passou pela maceração e outra não, em seguida, todos os feijões foram cozidos. As amostras cozidas foram liofilizadas, moídas e depois acondicionas em potes e armazenadas a temperaturas de -23ºC. As análises de composição centesimal, determinação da digestibilidade proteica, teores de tanino condensado e ácido fítico foram feitas utilizando as amostras moídas. Utilizando grãos inteiros, foram feitas análises de capacidade expansão e hidratação, tempo de cocção e cor instrumental. A irradiação não alterou a composição centesimal das amostras maceradas e sem macerar. Os teores de taninos condensados não reduziram conforme o aumento das doses. As concentrações de ácido fítico foram reduzidas nas doses de 5 e 10 kGy, para amostras maceradas, enquanto que para os feijões sem macerar, a irradiação gama não influenciou nos teores de fitatos. Ocorreu diminuição da digestibilidade proteica, nas amostras maceradas, a partir dose de 1 kGy, e as demais doses a redução não foi significativa. Já para os feijões sem macerar, houve aumento da digestibilidade, na dose de 10 kGy. Conforme o aumento das doses foi observado redução nos tempos de cocção dos feijões macerados e sem macerar. Na dose de 10 kGy, a capacidade de expansão do feijão aumentou. A coloração das amostras não modificou significativamente conforme o aumento das doses. Desta forma conclui-se que a radiação ionizante não influencia na composição centesimal e nos teores de taninos. A irradiação influenciou nos teores de ácido fítico em altas doses aplicadas, mas somente nas amostras maceradas, além de atenuar a digestibilidade proteica de feijões macerados. Reduz os tempos de cocção. Eleva a capacidade de expansão do feijão na dose de 10 kGy, porém não altera a coloração do feijão, conforme o aumento das doses / The common bean is an important component in the diet of the average Brazilian person. Each harvest of beans, losses occur due to attacks of insects and rodents. One of the ways to preserve the beans, and at the same time keep its nutritional characteristics, is the use of gamma radiation. This study aimed to evaluate the effects of different doses of gamma radiation on the physical and chemical properties of the carioca variety of common beans subject to cooking of soaked and unsoaked beans. Portions of raw beans were used as control and the other was subject to ionizing radiation at doses of 1, 5 and 10 kGy. Following irradiation, a portion of the samples (control and irradiated) were soaked and the other was not, then all beans were cooked. The cooked samples were lyophilized, milled and then accommodated in pots and stored at -23ºC temperatures. The analysis of chemical composition, determination of protein digestibility, condensed tannin and phytic acid content were performed using the milled samples. Using whole grains, were performed analysis of expansion capability and hydration, cooking time and instrumental color. Irradiation did not alter the chemical composition of soaked and unsoaked samples. The condensed tannin levels did not reduce according to increased doses. The phytic acid concentrations were reduced at the doses of 5 and 10 kGy for soaked samples, whereas for the not soaked beans, gamma irradiation did not influence the phytate content. The protein digestibility decreased on soaked samples, at doses of 1 kGy and in the other doses, the reduction was not significant. As for not soaked beans, increases in digestibility were observed at dose of 10 kGy. As the doses increased, reduction in cooking time on soaked and unsoaked beans was noted. At a dose of 10 kGy, the bean expansion capability increased. The samples\' color did not change significantly, as the doses increased. Therefore, it is concluded that ionizing radiation has no effect on the chemical composition and tannin content. Irradiation influenced the phytates when applied in higher doses, but only in soaked samples, as well as mitigate protein digestibility on soaked beans. It reduces cooking time, raises bean expansion capability at a 10 kGy dose, but it does not change the bean color as doses increase

Introdução: Doenças cardiovasculares constituem importante causa de morte em todo mundo e a hipercolesterolemia está diretamente relacionada a elas. A dieta desempenha papel importante neste processo e alguns alimentos como o feijão caupi (Vigna unguiculata L. Walp), especialmente sua proteína, tem sido apontado com potencial capacidade de redução do colesterol plasmático. Os efeitos hipocolesterolêmicos já observados indicaram o uso da proteína do feijão caupi, ou dos seus peptídeos, como ingrediente funcional de alimentos para a promoção da saúde e a redução do risco de doenças. Entretanto, as consequências da digestão gastrointestinal na absorção destes peptídeos são claramente complexas tornando essenciais estudos in vitro e in vivo para avaliar a sua bioacessibilidade e sua resistência à degradação gastrointestinal, além da disponibilidade e real eficácia destes peptídeos. Objetivo: Analisar a biodisponibilidade de peptídeos e avaliar parâmetros ligados ao metabolismo do colesterol em modelos animais após ingestão de isolado proteico de feijão caupi. Métodos: A farinha de feijão caupi foi desengordurada e sua proteína isolada. O isolado proteico foi submetido a métodos de hidrólise in vitro, para verificação das frações peptídicas formadas e inferência sobre a capacidade de ligação à albumina. Dois experimentos in vivo foram conduzidos. No primeiro, o isolado proteico do feijão caupi foi administrado a ratos e a concentração dos peptídeos monitorada no sangue, por 2 horas. O experimento in vivo 2 consistiu na alimentação de hamsters com dietas normo (N) - e hipercolesterolêmicas por 21 dias, contendo a proteína do feijão caupi como única proteína da ração (I), comparada ao controle de caseína (H). Neste experimento foram analisados no plasma: colesterol total (CT) e frações (LDLc, VLDLc e HDLc), triglicerídeos (TG) e peptídeos; nas fezes: colesterol total (CF) e ácidos biliares (AB); no fígado: colesterol (CH) e lipídeos totais (LH), HMGCR (atividade enzimática e expressão) e expressão de SREBP2, LDLR, ABCA1, ABCG1, ABCG5, ABCG8, LXRa e AMPK. Resultados: Os peptídeos identificados a partir da hidrólise proteica do feijão caupi, ou a partir do plasma dos animais estudados não evidenciaram similaridades entre os experimentos ou corresponderam a sequências previamente identificadas para o feijão caupi a partir de banco de dados. CT, VLDLc, HDLc, TG, CH dos hamsters foram maiores nos grupos H e I quando comparado ao N; LDLc foi maior para I comparado aos demais; LH foi maior em H comparado a N, sendo que I não diferiu dos demais; CF foi maior para I comparado a N, sendo que H não diferiu dos demais. A expressão de ABCA1 foi maior para I em relação aos demais; LXRa foi maior para I em relação a H, mas N não diferiu dos demais; SREBP2 foi menor em H em comparação aos demais; HMGCR foi mais expressa em N em comparação aos demais, ao passo que a atividade desta enzima foi maior em I quando comparado a N, sendo que H não diferiu dos demais. Não houve diferença entre os grupos quanto a AB ou expressão de ABCG8 ou AMPK. Não foram obtidos resultados de expressão para LDLR, ABCG1 e ABCG5. Conclusão: Apesar de pesquisas anteriores a este trabalho terem evidenciado a capacidade do isolado proteico do feijão caupi em inibir a atividade da HMGCR, inibir a solubilização micelar ou melhorar o perfil de lipídeos plasmáticos, no trabalho atual esta matéria prima não mostrou atuação positiva quanto ao metabolismo do colesterol de hamsters nas condições experimentais utilizadas. Os fragmentos indicados como peptídeos obtidos a partir da hidrólise proteica do feijão caupi, ou do plasma dos animais estudados não corresponderam a peptídeos com comprovada, ou até mesmo, com indicação de bioatividade / Introduction: Cardiovascular diseases are important cause of death worldwide and hypercholesterolemia is directly related to them. Diet plays an important role in this process and some foods such as cowpea (Vigna unguiculata L. Walp), especially its protein, have been shown to have a potential for reducing plasma cholesterol. The hypocholesterolemic effects already observed indicated the use of cowpea protein, or its peptides, as a functional food ingredient for health promotion and reduction of disease risk. However, the consequences of gastrointestinal digestion on the absorption of these peptides are clearly complex, making in vitro and in vivo studies essential to assess their bioaccessibility and resistance to gastrointestinal degradation, as well as the availability and actual efficacy of these peptides. Objectives: To analyze the bioavailability of peptides and evaluate parameters related to cholesterol metabolism in animal models after ingestion of protein isolate of cowpea. Methods: Cowpea flour was defatted and its protein isolated. The protein isolate was subjected to in vitro hydrolysis methods to verify the formed peptide fractions and inference about albumin binding ability. Two in vivo experiments were conducted. In the first, the cowpea protein isolate was administered to rats and the concentration of the peptides monitored in the blood for 2 hours. The in vivo experiment 2 consisted of feeding hamsters with normal (N) - and hypercholesterolemic diets for 21 days, containing the cowpea protein as the sole dietary protein (I), compared to casein control (H). In this experiment were analyzed in the plasma: total cholesterol (TC) and fractions (LDLc, VLDLc and HDLc), triglycerides (TG) and peptides; In feces: total cholesterol (CF) and bile acids (AB); In the liver: cholesterol (CH) and total lipids (LH), HMGCR (enzymatic activity and expression) and expression of SREBP2, LDLR, ABCA1, ABCG1, ABCG5, ABCG8, LXRa and AMPK. XX. Results: The peptides identified from the protein hydrolysis of cowpea or from the plasma of the animals studied did not show similarities among the experiments or correspond to sequences previously identified for the cowpea from the database. CT, VLDLc, HDLc, TG, CH of hamsters were higher in groups H and I when compared to N; LDLc was higher for I compared to the others; LH was higher in H compared to N, and I did not differ from the others; CF was higher for I compared to N, and H did not differ from the others. The expression of ABCA1 was higher for I than the others; LXRa was higher for I than H, but N did not differ from the others; SREBP2 was lower in H compared to the others; HMGCR was more expressed in N compared to the others, whereas the activity of this enzyme was higher in I when compared to N, and H did not differ from the others. There was no difference between groups regarding AB or expression of ABCG8 or AMPK. No expression results were obtained for LDLR, ABCG1 and ABCG5. Conclusion: Although previous research to this work evidenced the ability of the cowpea protein isolate to inhibit HMGCR activity, inhibit micellar solubilization or improve the plasma lipid profile, in the current work this raw material did not show a positive cholesterol metabolism of hamsters under the experimental conditions used. The fragments indicated as peptides obtained from the protein hydrolysis of cowpea beans, or from the plasma of the animals studied did not correspond to peptides with proven, or even, with indication of bioactivity
