TESTE DE VIGOR
Abstract in Portuguese
O presente trabalho foi conduzido na Escola Superior de Agricultura Luiz de Queiroz com o principal objetivo de se estudar a eficiência de testes de vigor para avaliar o desempenho de lotes de sementes de soja (Glycine max (L.) Merrill) durante a armazenagem. Cinco lotes do cultivar IAS-5 procedentes da região de Orlandia, Estado de são Paulo, foram periodicamente submetidas aos seguintes testes: germinação, primeira contagem de germinação, envelhecimento rápido, condutividade elétrica, emergência em areia, peso de matéria seca, comprimento da plântula e do epicotilo e emergência no campo. A análise estatística dos dados e a interpretação dos resultados permitiram que se chegasse ãs seguintes conclusões: a) os testes aplicados sobre as sementes de soja não detectaram possíveis diferenças fisiológicas entre os distintos lotes; b) os lotes mostraram possuir boa qualidade e homogeneidade e as sementes armazenadas em ambiente normal apresentaram melhor desempenho que as conservadas em câmara seca.

Vigor testes for soybean (Glycine max (L.) Merrill) seeds stored in two environments
Abstract in English
This work was conducted in the Escola Superior de Agricultura Luiz de Queiroz, University of São Paulo, with the main objective of studying the seed vigor testes eficiency to evaluate soybean (Glycine max (L.) Merrill) seed lots performance during storage. Five lots of the IAS-5 cultivar, from Orlandia region, state of São Paulo were periodically submited to the following tests: germination, first-count, accelerated aging, conductivity, sand emergency, dry matter weight, seedling lenght, epicotyl lenght and field emergency. The statistical analysis of data and interpretation of the results led to following conclusions: a) the imposed tests did not detect possible-physiological differences among seed lots; b) the lots showed good quality and homogeneity and the seeds stored in normal environmental condition showed better performance than those kept in dry chamber.
