Resumo: Sweet sorghum seeds (Sorghum bicolor (L.) Moench), cv BR-501, at two maturity stages with and without glumes were used in this study. The objectives were: 1) to identify if the glumes have influence on the water absortion by the seed; 2) to detect and characterize the inhibitors present in the glumes, since the removal of the glumes causes an increase in the physiological quality of the seed. Seeds with glumes present a higher imbibition velocity, maybe due to higher water retention in the glumes. However, mature seeds with glumes showed higher percentage of absorbed water. So, it was concluded that the glumes do not have influence on water absortion by the seeds, considering the occurrence of imbibition stabilization around 13 hours for mature seeds with and without glumes, and 11 hours for immature seeds. In relation to the presence of inhibitors the conclusion is that the immature sorghum seed glumes have fenolic inhibitors which are not detected in the glumes of mature seeds.

Moench) cultivar BR-501, imaturas e maduras, com ou sem glumas. O objetivo foi verificar se as glumas exercem influência na absorção de água pelas sementes, e detectar e caracterizar os inibidores nelas presentes, uma vez que a retirada das glumas acarreta um aumento na germinação e vigor. Sementes com glumas apresentam maior velocidade de embebição, provavelmente devido à maior retenção de água exercida por estas estruturas. Entretanto, as sementes maduras com glumas foram as que apresentaram maior teor de água absorvida. Conclui-se que as glumas não exercem influência sobre a absorção de água, pois ocorre uma estabilização da embebição em torno de treze horas para sementes maduras (com e sem glumas), e de onze horas para imaturas (com e sem glumas). Em relação à presença de inibidores, conclui-se que as glumas de sementes de sorgo imaturas possuem inibidores fenólicos, cuja presença não é detectada nestas estruturas, em sementes maduras.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileirados Santos, Dora Suely BarbosaTillmann, Maria Angela AndréPeters, José Antônio1991-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/3432Pesquisa Agropecuaria Brasileira; v.26, n.7, jul. 1991; 989-993Pesquisa Agropecuária Brasileira; v.26, n.7, jul. 1991; 989-9931678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/3432/765info:eu-repo/semantics/openAccess2009-12-15T14:45:51Zoai:ojs.seer.sct.embrapa.br:article/3432Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2009-12-15T14:45:51Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
