Resumo: This research aimed to evaluate the growth and sporulation of two Verticillium lecanii (Zimm.) Viégas isolates cultivated on solid medium with different initial pH values (4, 5, 6, 7, 8 and 9), exposed to different temperatures (19, 22, 25, 28 and 31°C) and photoperiods (0, 12 and 24 hours). There was no substantial effect of the initial pH values on growth and sporulation of both isolates twenty days after inoculation, except at pH 4.0 in which the growth was significantly reduced. Absence of light promoted the best growth of JAB 02 (32.70 mm) and JAB 45 (32.67 mm) isolates but there was no effect of photoperiod on sporulation. The best temperatures for growth of JAB 02 were 19, 22 and 25°C and for JAB 45, 19 and 25°C. The latter isolate sporulated most at 19 and 22°C and there was no effect of temperature on sporulation of JAB 02. None of the isolates developed at 31°C.

Viégas, submetidos a diferentes valores de pH (4, 5, 6, 7, 8, 9) inicial do meio de cultivo sólido, de temperatura (19, 22, 25, 28 e 31°C) e fotoperíodo (0, 12 e 24 horas). Após 20 dias de cultivo, não se observou efeito do pH inicial do meio no crescimento e esporulação dos isolados, exceto no pH 4,0 que reduziu o crescimento. A ausência de iluminação proporcionou a melhor condição para o crescimento de JAB 02 (32,70 mm) e JAB 45 (32,67 mm). Não houve efeito do fotoperíodo na produção de esporos. As melhores temperaturas para o crescimento de JAB 02 foram 19, 22 e 25°C e para JAB 45 foram 19 e 25°C. Este último isolado apresentou melhor esporulação a 19 e 22°C, mas a temperatura não influenciou a esporulação de JAB 02. Não houve desenvolvimento dos isolados a 31°C.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMonteiro, Antonio CarlosBarbosa, Claudio CamargoCorreia, Antônia do Carmo BarcelosPereira, Gener Tadeu2004-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6808Pesquisa Agropecuaria Brasileira; v.39, n.6, jun. 2004; 561-565Pesquisa Agropecuária Brasileira; v.39, n.6, jun. 2004; 561-5651678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6808/3864info:eu-repo/semantics/openAccess2014-07-21T19:00:01Zoai:ojs.seer.sct.embrapa.br:article/6808Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-21T19:00:01Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
