Infection rates of perennial ryegrass seeds (Lolium perenne L.) with different fungi.

Authors made investigations to map occurrence of different fungal pathogens on seeds of varieties from different grass species. This work presents data on three cultivars of perennial ryegrass (Lolium perenne L.). When seeds were germinated, eight genuses of fungi were identified belonging to the Deuteromycota. Alternaria was the most frequently occurred genus. Drechslera, Bipolaris, Cladosporium, Stemphylium, and Epicoccum spp. has also been found in the seed samples. Two genus of fungal pathogens (Embellisia and Septonema) were identified which were not mentioned in Hungary so far.
