The aim of the experiment was to determine the effects of storage conditions on the incidence of fungi on spring barley grain and its quality. Spring barley grain (cultivars Rastik and Rataj) was harvested in three years (2000, 2001, 2002), using extensive, conventional and intensive cultivation systems, stored in hygrostats at controlled relative air humidity, 40, 60 and 85%, respectively and at variable temperatures 15-20°C for two months. It was found that spring barley grain (Rastik, Rataj) stored in the medium at 40 and 60% relative air humidity retained its good health, quality and germination rate. Among the fungi isolated from this grain the following were predominant: Alternaria alternata (45-57%) Bipolaris sorokiniana (9-22%), Epicoccum purpurascens (5-17%) and fungi from the genus Fusarium (9-20%). On the grain stored at 85% relative air humidity a substantial increase of “storage fungi” was observed, especially Penicillin spp. (32-67%),) which probably caused the health, quality and germination capacity of the grain to deteriorate. Spring barley grain (cultivar Rataj) was more infected by fungi than Rastik.
