Resumo: The objective of this work was to evaluate the storage effect on seed physiological quality of five tropical maize (Zea mays L.) populations, under stress conditions, including acid soil and drought. Five maize populations (CMS06, CMS35, CMS36, CMS54 and Milho Metro) were cultivated in soils with two types of fertility (67% of base saturation and 54% of Al saturation), with and without irrigation during flowering. After harvest, the seeds were stored in the laboratory under environmental conditions. The physiological quality of seeds, germination and vigor, were determined in the start of the storage, 30, 90 and 210 days after starting storage. The seeds of the population CMS36 presented higher vigor when produced under high aluminum saturation. The population CMS54 presented highest stability related to physiological quality. The seeds of the populations CMS35, CMS36, CMS54 and Milho Metro presented higher stability related to physiological quality than the CMS06, during storage.

Cinco populações de milho (CMS06, CMS35, CMS36, CMS54 e Milho Metro) foram cultivadas em solos com dois níveis de fertilidade: o primeiro, apresentando alta saturação de bases (V = 67%), e o segundo, alta saturação de Al (m = 54%). As populações de milho foram também submetidas à irrigação plena e à supressão de irrigação durante o florescimento. As sementes obtidas dessas populações foram armazenadas no laboratório de sementes sob condições ambientais. A qualidade fisiológica das sementes foi determinada no início e aos 30, 90 e 210 dias de armazenamento. As sementes da população CMS36 apresentaram maior vigor quando produzidas em solos com alta saturação de alumínio. A população CMS54 foi a mais estável com relação à qualidade fisiológica das sementes produzidas em diferentes ambientes. As sementes das populações CMS35, CMS36, CMS54 e Milho Metro foram mais estáveis com relação à qualidade fisiológica, durante o período de armazenamento, do que as da CMS06.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGuarçoni, Rogério CarvalhoDurães, Frederico Ozanan MachadoMagalhães, Paulo CésarSilva, Roberto Ferreira da2001-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6282Pesquisa Agropecuaria Brasileira; v.36, n.12, dez. 2001; 1479-1484Pesquisa Agropecuária Brasileira; v.36, n.12, dez. 2001; 1479-14841678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6282/3347info:eu-repo/semantics/openAccess2010-08-05T16:15:53Zoai:ojs.seer.sct.embrapa.br:article/6282Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-05T16:15:53Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
