Resumo: Although recommended for evaluation of seed lot vigor, artificial aging test shows results variability for reasons yet to be elucidated. Seed-fungi association is considered one of the causes responsible for such variation. The goal of this work was to verify the effects of periods of artificial aging on bean seed behavior and on Aspergillus spp., Penicillium spp., Fusarium oxysporum and Colletotrichum lindemuthianum fungi artificially inoculated by contact method. Health, germination, tetrazolium, emergence, electrical conductivity and potassium leaching tests were performed for seed behavior evaluation. The answers achieved, besides dependable on the aging time period, indicated the effect of fungi species associated to the seed. The artificial aging test was found to be associated with the expression of physiological and sanitary causes that interfere with data interpretation; the presence of fungi, mainly Aspergillus spp., may be considered capable of interfering in the behavior of artificially aged seeds in a negative way.

Este trabalho objetivou verificar os efeitos de diferentes períodos de envelhecimento artificial, no comportamento fisiológico de sementes do feijoeiro e dos fungos Aspergillus spp., Penicillium spp., Fusarium oxysporum e Colletotrichum lindemuthianum, inoculados artificialmente. Foram conduzidos testes de sanidade, germinação, tetrazólio, emergência, condutividade elétrica e lixiviação de potássio. As respostas obtidas, dependentes da duração do período de envelhecimento, indicaram efeitos da espécie fúngica presente. Concluiu-se que o teste de envelhecimento artificial associa a expressão de causas fisiológicas e sanitárias, o que prejudica a interpretação dos dados obtidos; a presença de fungos, principalmente de Aspergillus spp., pode ser considerada como capaz de interferir de modo negativo no desempenho das sementes envelhecidas artificialmente.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilva, Monalisa Alves Diniz daSilva, Walter Rodrigues da2000-03-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5826Pesquisa Agropecuaria Brasileira; v.35, n.3, mar. 2000; 599-608Pesquisa Agropecuária Brasileira; v.35, n.3, mar. 2000; 599-6081678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5826/2930info:eu-repo/semantics/openAccess2014-08-15T17:56:32Zoai:ojs.seer.sct.embrapa.br:article/5826Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-15T17:56:32Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
