Resumo: The chlamydospores of Entyloma vignae Batista, Bezerra, Ponte and Vasconcelos, collected from the infected leaves of cowpea (Vigna unguiculata (L.) Walp.) were germinated and produced nonseptate promycelia of variable length. The promycelium was characterized by branching at the distal end bearing clusters of 10 to 20 primary sporidia. The adjacent compatible primary sporidia exhibited fusion in pairs forming typical H - shaped structures. The secondary infective mycelium inducing leaf lesions had originated from the fused primary sporidia. The mycelium in the culture produced clusters of chlamydospores which were nonpathogenic.

Walp.) infectadas. Os clamidósporos germinaram, produzindo promicélio não septado, com comprimento variável. O promicélio apresentou ramificações terminais com grupos de esporídios primários variando de 10 a 20. Os esporídios primários, adjacentes e compatíveis, exibiam fusão entre pares, formando estruturas típicas de letra "H". O micélio secundário, induzindo testes nas folhas originou-se de esporídios primários, após a fusão. O micélio em cultura produziu clamidósporos não patogênicos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPrabhu, Anne SitaramaAlbuquerque, Fernando Carneiro2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15687Pesquisa Agropecuaria Brasileira; v.17, n.3, mar. 1982; 413-416Pesquisa Agropecuária Brasileira; v.17, n.3, mar. 1982; 413-4161678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/15687/9689info:eu-repo/semantics/openAccess2014-04-16T12:34:35Zoai:ojs.seer.sct.embrapa.br:article/15687Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T12:34:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
