Avaliação do perfil de produtos hortifrutigranjeiros comercializados nas feiras livres de Garanhuns
(Universidade Federal Rural de Pernambuco (SEDE); Unidade Acadêmica de Garanhuns; Administração, 2011) Moser, Luciana Maia
Os projetos desenvolvidos no meio acadêmico com a participação do corpo docente e discente devem priorizar e estimular a cidadania e a inclusão social, proporcionando uma integração entre a universidade e a sociedade. Assim, dentre os vários fatores que podem influenciar na vida saudável das populações, destaca-se a alimentação. Uma alimentação rica em frutas, verduras e legumes, tem valor inestimável para a saúde pública, sendo responsável, inclusive pela prevenção de doenças. Entretanto, o uso frequente de agrotóxicos e de forma inadequada na produção dos artigos hortifrutigranjeiros, pode trazer consequências graves tanto para a população que consome esses alimentos como também aos agricultores e trabalhadores rurais. Dessa forma, o presente projeto tem por finalidade avaliar a procedência dos produtos hortifrutigranjeiros, comercializados em feiras livres na cidade de Garanhuns, quanto ao local de cultivo, sistema de produção e uso de agrotóxicos nessa produção. Além disso, será traçado o perfil dos feirantes que são produtores rurais e suas propriedades serão visitadas e acompanhadas. Posteriormente, serão ministradas palestras sobre alimentos orgânicos e alimentos funcionais e cartilhas serão confeccionadas e distribuídas nas feiras livres tanto para os feirantes como também para os consumidores.
Efeito de estresses combinados salino e de altas temperaturas em Vigna unguiculata (L.) Walp: abordagens fisiológicas e anatômicas

Salinity and high temperatures are factors that negatively affect the production of plant species of socioeconomic importance in arid and semi-arid waters. At present, major reactions from plant technicians are covered and information on environmental conditions is included. Cowpea (Vigna unguiculata (L.) Walp) is one of the most important crops of the region. In addition, it is a moderately resistant strategy to drought and salt stress, stressing principles that limit the productivity of this crop. The present work had as physiological and anatomical objective of the rope bean on the effect of saline stresses and high temperatures. The experiments were conducted at UFRPE-UAG / CENLAG. Seeds of cowpea cultivar IPA 206 were seeded on filter paper moistened in distilled water or 100 mM NaCl solution (saline stress condition) and placed in a germination chamber with 12-hour photoperiod at temperatures of 30, 35 and 40°C for 7 days . The measures of the flexible ones were cut and their length was measured in relation to the analytical balance. For a physiological characterization, as were submitted to germination tests, IVG, analysis of root and shoot root length and dry mass, and anatomical analysis from histological sections of hypocotyls. The results were: the interaction between salinity and high temperatures decreased the seed germination potential of V. unguiculata and the sampling rate was 40°C. Saline stress (100 mM NaCl) in the hot, diseased air (40°C) inhibited the growth, growth and dry mass of V. unguiculata seedlings. Saline stress associated with high temperatures caused disarrangement in the arrangement of xylem and phloem bundles in cowpea seedlings. Thus, the combined stresses potentiate the effects of saline and thermal stress alone.
Qualidade fisiológica de sementes crioulas de feijão-de-corda do Estado de Pernambuco

The physiological quality of seeds is one of the factors responsible for the good development of the plant in the field. In addition, stress conditions (such as saline and water) during the germination phase can also affect seedling emergence and consequently the vegetative development of crops. Therefore, this work aimed to study the physiological quality of black bean seeds from Pernambuco State. These seeds were supplied by farmers and / or associations of farmers from Agreste and Sertão Pernambuco, the experiments were carried out at the CENLAG Plant Production Laboratory of the Garanhuns Academic Unit. The evaluation of seed biometrics was performed by measuring length, width and thickness. In addition to these parameters, the weight of 100 seeds and the water content were also measured. The physiological quality of the seeds was measured by germination parameters (IVG,% of germination and effect of water and saline stress on germination), as well as seedling length and dry mass. Creole seed samples of string beans from the municipalities of Canhotinho, Sao Joao, Garanhuns, Jucati, Brejinho and Serra Talhada were heterogeneous in color and size. The sample from Garanhuns presented the highest water content (15.05) and the smallest from Brejinho (2.56). In the germination percentage, there was variation using the two parameters (radicle emission and normal seedlings), where the sample of the municipality of Brejinho presented the best germination results (100% considering the radicle emission and 20% considering normal seedlings). Garanhuns and São João samples presented the worst 84% considering radicle emission and 1% considering normal seedlings respectively. The samples that were most affected by water and saline stress in germination and IVG of normal seedlings were from São João and Garanhuns, which did not obtain normal seedlings. Seedling growth was affected by saline and water stress, which caused reduction in shoot and root length, being the most severe salt stress. The seedlings from the Canhotinho sample are the most sensitive to saline stress in relation to shoot length and shoot and root dry mass.
