Resumo: Corn seeds were harvested with 16% and 21% of moisture content and dryed for 0, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144 and 156 hours after harvest to verify the effect of delaying desiccation on germination and vigor. The results pointed out that to obtain seed germination over 85%, seed drying may be retarded up to 84 hours when seeds were harvested with 21% of moisture content. The physiological quality of seeds decreased significantly when seed drying was retarded for more than 84 hours after harvesting seeds with high moisture content (21%). The physiological quality was not affected when seeds were harvested with low moisture content (16,0%) and desiccated up to 156 hours.

A secagem da semente foi adiada por 0, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144 e 156 horas, e a germinação e o vigor foram determinados imediatamente após a secagem. Os resultados indicam que as sementes colhidas com 21% de umidade podem ter sua secagem retardada até 84 horas. Acima de 84 horas foram observados decréscimos significativos na qualidade fisiológica da semente. Sementes colhidas com baixa umidade (16%) não foram afetadas em sua qualidade fisiológica quando secadas até 156 horas após a colheita.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilveira Borba, CleversonAndreoli, ClaudineiVilela de Andrade, RamiroTito de Azevedo, JoãoCarlos de Oliveira, Antonio1998-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4827Pesquisa Agropecuaria Brasileira; v.33, n.1, jan. 1998; 105-108Pesquisa Agropecuária Brasileira; v.33, n.1, jan. 1998; 105-1081678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4827/6938info:eu-repo/semantics/openAccess2014-11-10T19:27:22Zoai:ojs.seer.sct.embrapa.br:article/4827Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-10T19:27:22Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
