Resumo: http://dx.doi.org/10.5902/198050986617Researches about seed pathology of native forest species, especially, those more extensive, are rare. This research aims to evaluate the health of “cedro” (cedar) seeds through two detection methods, to evaluate the possible transmission of fungi Cedrela fissilis seeds to seedlings and to evaluate the pathogenicity of the fungus transmitted by Cedrela fissilis seeds. For this, seeds from six different locations from Rio Grande do Sul, Santa Catarina and Paraná states were used. The seeds were submitted to sanity tests, by blotter-test and potato-dextrose-agar (PDA) methods, transmission by seeds to the seedlings and to the pathogenicity test of Rhizoctonia sp., chosen because it was common in sanity testing and transmitted by seed. The fungi found in both of the methods were: Pestalotia sp., Rhizoctonia sp., Penicillium sp., Phomopsis sp., Rhizopus sp., Aspergillus sp. and Fusarium sp. Both tests can be used for the sanity test in Cedrela fissilis seeds. The fungi transmitted by seeds to the seedlings were Fusarium sp. and Rhizoctonia sp., both causing problems in roots and subsequent damping-off. One of the isolates of Rhizoctonia sp. was identified as pathogenic to seedlings, causing the same symptoms observed on transmission test.

Assim, o objetivo deste estudo foi avaliar a sanidade das sementes de cedro através de dois métodos de detecção, avaliar a transmissão de fungos associados às sementes para as plântulas e avaliar a patogenicidade de fungos associados às sementes e transmitidos para as plântulas. Para tanto, sementes de seis procedências, dentre os estados do Rio Grande do Sul, Santa Catarina e Paraná, foram utilizadas. Estas foram submetidas a testes de sanidade, pelos métodos do papel-filtro e batata-dextrose-ágar (BDA), a teste de transmissão via sementes para as plântulas e a teste de patogenicidade de isolados de Rhizoctonia sp., patógeno escolhido por ser o mais frequente nos testes de sanidade e transmitido via semente. Os fungos encontrados em ambos os testes foram: Pestalotia sp., Rhizoctonia sp., Penicillium sp., Phomopsis sp., Rhizopus sp., Aspergillus sp. e Fusarium sp. Ambos os métodos podem ser utilizados para teste de sanidade em sementes de cedro. Os fungos transmitidos via semente para plântula foram Fusarium sp. e Rhizoctonia sp., sendo que, estes causaram danos nas raízes e posterior tombamento. Foi identificado um isolado de Rhizoctonia sp. patogênico para plântulas de cedro, causando os mesmos sintomas relatados no teste de transmissão.Universidade Federal de Santa Maria2012-09-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/661710.5902/198050986617Ciência Florestal; Vol. 22 No. 3 (2012); 493-503Ciência Florestal; v. 22 n. 3 (2012); 493-5031980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/6617/4056Lazarotto, MaríliaMuniz, Marlove Fátima BriãoBeltrame, RafaelSantos, Álvaro Figueiredo dosMaciel, Caciara GonzattoLonghi, Solon Jonasinfo:eu-repo/semantics/openAccess2017-04-20T13:02:20Zoai:ojs.pkp.sfu.ca:article/6617Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-20T13:02:20Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
