Resumo: Canker symptoms were observed in African mahogany plantations in Dom Eliseu County, Para State, Brazil. Fungi associated with symptomatic tissues were identified as Lasiodiplodia theobromae and Fusarium subglutinans. Pure cultures of these fungi were tested for pathogenicity on healthy young plants of African mahogany. Only L. theobromae produced canker, using wound inoculation technique and high humidity. The confirmation of L. theobromae as the causal agent of canker came after the reisolation of this fungus from inoculated plants in greenhouse, concluding the first verification of Koch’s postulates for this pathosystem.

Os fungos associados aos tecidos sintomáticos foram identificados como Lasiodiplodia theobromae e Fusarium subglutinans. Culturas puras desses fungos foram testadas quanto à patogenicidade em mudas de mogno africano sadias. Apenas L. theobromae produziu cancro, por meio de inoculação por ferimento e alta umidade. A confirmação de L. theobromae como agente causal do cancro ocorreu após o reisolamento do fungo a partir das plantas inoculadas em casa de vegetação, concluindo a primeira verificação do postulado de Koch para esse patossistema.Embrapa Florestas2013-06-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/41510.4336/2013.pfb.33.74.415Pesquisa Florestal Brasileira; v. 33 n. 74 (2013): abr./jun.; 221-225Pesquisa Florestal Brasileira; Vol. 33 No. 74 (2013): abr./jun.; 221-2251983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/415/pdf_37Tremacoldi, Célia ReginaLunz, Alexandre MehlCoelho, Iwanne LimaBoari, Alessandra de Jesusinfo:eu-repo/semantics/openAccess2017-04-28T12:52:27Zoai:pfb.cnpf.embrapa.br/pfb:article/415Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T12:52:27Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
