Resumo: Maturation of soybean (Glycine max (L.) Merrill) seeds of ‘Bragg' and ‘UFV-1' cultivars was studied. Plant development and seed maturation were studied in randomized blocks field experiments planted in 1977 and 1978. Beginning of flowering and fruiting were dated when the plots had five to ten plants per square meter with one flower or one fruit raceme, respectively. The seeds were harvested seven times each year; after each harvest, the following data were obtained: moisture content, dry weight, tegument and hilum color (Munsell system), germination and vigor of seeds. The absence of yellow-green seeds with homocrome hilum and the loss of green color from the pods represent useful and acceptable indicators of physiological maturity. Maximum soybean seed dry weight was found to be insufficient by itself to characterize physiological maturity.

Merrill), cultivares ‘Bragg' e ‘UFV-1', procurando associar a maturidade fisiológica a características morfológicas das sementes e das plantas. Para tanto, foram instalados experimentos de campo em delineamento de blocos casualizados, em novembro de 1977 e de 1978. Considerou-se como início do florescimento o momento em que foi constatada, por amostragem, a presença de cinco a dez plantas com, pelo menos, um racemo florescido por metro quadrado; o mesmo método foi utilizado para determinar o inicio da frutificação. Após as colheitas, efetuadas a intervalos semanais, foram avaliados, o teor de umidade, o peso da matéria seca, a germinação e o vigor das sementes, bem como a coloração das sementes e a do hilo (segundo o sistema Munsell). Após as análises dos dados e a interpretação dos resultados, concluiu-se que a coloração das sementes, do hilo e das vagens permite identificar a maturidade fisiológica de sementes de soja. Porém, o peso da matéria seca não se mostrou suficiente para caracterizar a maturidade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMarcos Filho, Julio2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16620Pesquisa Agropecuaria Brasileira; v.15, n.4, abr. 1980; 447-460Pesquisa Agropecuária Brasileira; v.15, n.4, abr. 1980; 447-4601678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16620/10918info:eu-repo/semantics/openAccess2014-04-15T19:35:38Zoai:ojs.seer.sct.embrapa.br:article/16620Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:35:38Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
