    Opis:
    Seeds of 5 cultivars of spring barley, originated from field experiments conducted in 2000 at Radzików, were tested immediately after harvest and after three, four and five years of storage in uncontrolled conditions, for incidence of seed-borne fungi with special regard to “field fungi” (Bipolaris sorokiniana and Fusarium spp.) and "storage fungi" (species of Penicillium and Aspergillus). The studies showed that barley seeds were infected before storage by numerous fungi as well as the saprophytes: Alternaria alternata, Acremonium spp., Acremoniella atra and the pathogens: Bipolaris sorokiniana and ten Fusarium species. The analysis after storage showed that the frequency of fungal infection had changed. The occurrence of some fungi was significantly affected by the period of storage...

    Opis:
    The analysis of seed health and germination capacity of 7 varieties of Lolium perenne, originated from two breeding station and two seed company localized in different places of Poland, harvested in 2006, 2007 and 2008 were performed. Results of mentioned analysis indicated that seeds were contaminated by numerous species of fungi. The most numerous group of fungi were saprophytes or weak parasites such as: Alternaria alternata, Epicoccum nigrum, Septonema chaetospira and Penicillium spp. Pathogenic species were represented by species of Drechslera, Fusarium, Phoma, Curvularia lunata and Bipolaris sorokiniana. Seed germination capacity was influenced by contamination of fungi. It was found that seed more often contaminated by fungi germinated much poorer then seed with lower infection.

    Opis:
    Seeds of ten cultivars of spring wheat from five different localized breeding stations were tested for seedhealth. The same seeds were sown in Radzików in field experiment and its seed health after harvest was evaluatedalso. The basic material of wheat was infected by numerous fungi: 36 fungal species belonging to 24genera and the most often occurred: Alternaria alternata, Epicoccum purpurascens, Fusarium spp.,Drechslera spp. and B. sorokiniana. It was found significant differences between cultivars for total fungioccurred on seeds, for seed infection by main pathogens (B. sorokiniana, Drechslera spp. and Fusariumspp.). Also seeds from breeders were strongly infected by these pathogens in comparison to seeds harvested infield experiment in Radzików.

    Opis:
    The ergot (Claviceps purpurea) incidence in seed samples of Poa pratensis, Lolium perenne, L. multiflorum, Festuca rubra and F. pratensis cultivars originating from different regions of grass cultivation in Poland was detected in 1999 – 2002. Each year, about hundred twenty cultivars of different species were tested. It was found that number of seed replaced by sclerotia significantly varied and depended on the year of seed harvest, species and cultivar tested and region of grass grown for seed. The highest level of Claviceps purpurea sclerotia almost for all grass species was detected in 1999. The highest number of seed replaced by sclerotia was found in sowing material of Poa pratensis for all years of testing. Ergot in seed lots of L. multiflorum and F. pratensis were detected at trace levels. Differences in susceptibility to Claviceps purpurea among cultivars were observed. However, significant variation in occurrence of ergot sclerotia were noted for the same cultivar harvested in different region of Poland. It was found that size of sclerotia depended on the host - grass species and the year of seed harvest. Significant differences  were noted particularly in the length and weight of sclerotia.
