Patogeniczne grzyby zasiedlające nasiona łubinu wąskolistnego [Patogenic fungi associated with blue lupine seeds]

Abstract

Over 10% ofseeds harvested in 1991 and 1992 (50 samples, 400 seeds in each sample) proved to be infested with various fungi. Fusarium spp. and Botrytis cinerea were the most common pathogens isolated. Fusarium avenaceum was the most common and highly pathogenic species. Fusarium semitectum and F. tricinctum were highly pathogenic to lupin seedlings but they were the least common Fusarium isolated from seeds. Similarily, Sclerotinia sclerotiorum was isolated only from 0,2% seeds tested but this fungus was highly pathogenic to lupin seedlings. Some other fungi know as lupin pathogens (F. oxysporum, Stemphylium botryosum, Pleiochaeta setosa and Phomopsis leptostromiformis) were also noted in tested seeds.
