ABSTRACT
In Brazil, there is still scarce research on microorganisms associated with forest seeds. The aim of this study was to detect fungi associated with seeds of six native forest species: “açoita-cavalo” (Luehea divaricata), “araçá amarelo” (Psidium cattleyanum), “corticeira” (Erythrina falcata), “rabo-de-bugio” (Lonchocarpus sp.), “vassoura-vermelha” (Dodonea viscosa) and “pau-jacaré” (Piptadenia gonoacantha). Eight genera of fungi were identified as potentially pathogenic: Cladosporyum sp., Fusarium sp., Pestalotiopsis sp., Phomopsis sp., Coletotrichum sp., Alternaria sp., Phoma sp. and Botrytis sp., and saprophytic fungi: Aspergillus sp., Penicillium sp., Rhizopus sp., Epicoccum sp., Torula sp., Trichoderma sp., Gliocladium sp., Chaetomium sp. and Trichothecium sp. Results evidence the diversity of fungi associated with native forest seeds, including several potentially phytopathogenic fungi.
