Incidência e viabilidade de sementes crioulas de milho naturalmente infestadas com fungos em pré e pós-armazenamento

Abstract

The objective of this study was to evaluate the sanitary and physiological quality of fourteen varieties of creole corn seeds in pre-and post-storage in packaging of polyethylene terephthalate (PET). Among the mycobiota observed Fusarium moniliforme (88%), Penicillium spp. (6,9%) and Aspergillus spp. (2,1%) had the highest incidence. After storage there was a slight decrease in the percentage of F. moniliforme (69%) and a increase of Penicillium spp. (35%) and Aspergillus spp. (22%). The incidence of these fungi did not compromise the physiological quality of seeds that showed high percentages of vigor and germination.
