Fungi Associated with Capororoca (Myrsine ferruginea) Myrsinaceae Fruits and Seeds

Abstract

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 and
seeds 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.
