Relationship between seedborne fungi of red fescue (Festuca rubra) and seed germination capacity.


The analysis of seed health and germination capacity of seven cultivars of Festuca rubra harvested in 2006, 2007 and 2008 was performed. Seeds deriving from five different localizations in Poland were contaminated by different species of fungi. The most numerous group were saprotrophs or weak parasites such as: Alternaria alternata, Epicoccum nigrum, Aspergillus spp. and Penicillium spp. Pathogenic fungi were represented by species of Drechslera, Fusarium, Phoma, Rhizoctonia solani and Bipolaris sorokiniana. Seed germination was influenced by infection of fungi. Seeds more often infected by fungi germinated much poorer than seeds with lower infection degree.
