[Amylolytic activity of Fusarium LK:FR. and Alternaria NEES:FR. species].

A comparative study of saprophytic, plant pathogenic and endophytic strains of different Fusarium and Alternaria species was conducted. It was shown that amylolytic activity of Fusarium strains of different trophic groups was low or absent. Plant pathogenic Alternaria spp. strains possessed middle and high activity while endophytic ones had middle activity. Amylolytic activity of the studied Fusarium spp. and Alternaria spp. strains varied on the strain level. The dependence of amylolytic activity of the studied strains on species and organs of host plants, which they were isolated from, was not established. Correlation between the rate of linear growth of the studied strains on the media with soluble starch and amylolytic activity level was not shown.
