Os objetivos neste trabalho foram identificar os fungos associados aos frutos e sementes de capororoca (Myrsine ferruginea Spreng) obtidos de diferentes lotes e verificar a incidência de fungos entre frutos verdes e maduros e nas sementes obtidas destes frutos. Para a detecção de fungos utilizou-se o método de papel-filtro (PF), sendo 400 frutos e 400 sementes para cada amostra, incubadas sob 12 horas luz negra/12 horas escuro, na temperatura de 20 ºC ± 1 ºC durante sete dias, avaliando-se a incidência (%) de fungos. Pôde-se verificar a possível transmissão dos fungos Alternaria sp., Cladosporium sp., Colletotrichum sp., Fusarium sp., Macrophomina sp. e Pestalotia sp. dos frutos para as sementes. Nos três lotes avaliados, Pestalotia sp. apresentou a maior percentagem de incidência nas sementes. A contaminação fúngica nos frutos foi maior que nas sementes, indicando que o beneficiamento das sementes reduz o aparecimento de fungos. Houve diferença na ocorrência de fungos entre os lotes avaliados, sendo que o lote proveniente do Município de Colombo apresentou maior incidência de fungos. Doi: 10.4336/2009.pfb.58.87
The objectives of this study were to identify the fungi associated with capororoca (Myrsine ferruginea Spreng) fruits and seeds from different lots and check the incidence of fungi between green and ripe fruits andseeds from these fruits. For fungi detection Blotter test (BT) method was utilized, being 400 fruits and 400 seeds each sample, and incubated at 20 ºC ±1 ºC, 12 h dark light/12 h complete dark, for seven days, followed by the evaluation of the fungi incidence (%). It was possible to verify the transmission of the fungus Alternaria sp., Cladosporium sp., Colletotrichum sp., Fusarium sp., Macrophomina sp. and Pestalotia sp. fruit for seeds. Evaluated in three lots, Pestalotia sp. had the highest percentage of incidence in the seeds. The fungal contamination in fruits were higher than in seeds, indicating that the seed treatment reduces the appearance of fungi. There were differences in the occurrence of fungi among the lots evaluated, and the lot from Colombo County had higher incidence of fungi.doi: 10.4336/2009.pfb.58.87
