- The rice grain is frequently infected by a series of pathogens (fungi) during its storage, producing damages to the economy and health of humans. The aim of this study was to identify the fungal genera present in different rice genotypes and to quantify their variation during storage. Paddy, brown and milled rice fractions of Nutriar, (N) H329-5(H329) and Don Ignacio genotypes were analyzed at 4, 8 and 12 months of storage. Fungi were identified based on their micromorphological characteristics and colonies. The observed genera according to their frequency were: Alternaria, Nigrospora, Epicoccum, Bipolaris, Curvularia, Cladosporium and Fusarium (field fungi) and Penicillium and Aspergillus (storage fungi). The mycobiota composition was different depending on the grain fraction and the period of storage: field fungi were located in the hulls and bran layers, while storage fungi were mainly in the endosperm. The different genotypes showed different susceptibility to contamination.
O grão de arroz é, com frequência, atacado por uma série de patógenos (fungos) durante o armazenamento produzindo danos econômicos e à saúde humana. O objetivo do trabalho foi identificar os gêneros fúngicos presentes em diferentes genótipos de arroz e quantificar sua variação durante o armazenamento. Analisaram-se as frações casca, integral e polido dos genótipos Nutriar (N), H329-5 (H329) e Don Ignácio aos 4, 8 e 12 meses de armazenamento. Os fungos foram identificados por suas características micromorfológicas e suas colônias. Os gêneros observados segundo sua frequência foram: Alternaria, Nigrospora, Epicoccum, Bipolaris, Curvularia, Cladosporium e Fusarium (fungos de campo) e Penicillium e Aspergillus (fungos de armazenamento). A composição da micoflora foi diferente segundo fração de grão e tempo de armazenamento: os fungos de campo localizaram-se na casca e no farelo, enquanto os de armazenamento, no endosperma. Os diferentes genótipos apresentaram diferente suscetibilidade à contaminação.
