Abstrakt
Badania przeprowadzono w latach 1998-2000 na roślinach soi odmiany "Polan". Przedmiotem badań były liście i strąki soi, które poddano analizie mikrobiologicznej i mikologicznej. Z chorych organów soi znacznie częściej, aniżeli ze zdrowych, uzyskiwano bakterie i grzyby. W wyniku analizy mikologicznej liści i strąków soi uzyskano 778 izolatów grzybów. W obrębie grzybów chorobotwórczych najczęściej wyosobnianymi okazały się Fusarium spp. i Phomopsis sojae, bowiem ich udział stanowił odpowiednio 17,5% i 7,8% wszystkich grzybów. Natomiast spośród grzybów saprotroficznych izolowano m.in. gatunki z rodzajów Acremonium, Cladosporium, Gliocladium, Penici- llium i Trichoderma oraz Aureobasidium pullulans i Epicoccum purpurascens. Ponadto z porażonych organów soi izolowano około czterokrotnie mniej mikroorganizmów antagonistycznych (Bacillus spp., Pseudomonas spp., Gliocladium spp., Penicillium spp., Trichoderma spp.), aniżeli ze zdrowych.
