A comparative analysis of cellulase and xylanase activities of 26 fungal strains of phytopathogenic, saprophytic and endophytic Fusarium species has been realized using the qualitative reactions. The rare of their linear growth on the media with carboxymethyl cellulose or xylane has been studied. It was shown that the fungi of genus Fusarium belonging to different trophic groups possessed low activities of investigated enzymes as a whole, but in endophytic strains their levels were lower than in phytopathogenic ones. At the same time the distinct strain dependence of cellulase and xylanase activities was fixed in the fungi of different trophic groups. As far as the cellulase and xylanase activities in phytopathogenic isolates varied from complete absence to high levels, and since the activity maximum for each of the investigated strains was observed in different growth terms the conclusion was made that the cellulase and xylanase activities could not be considered as possible markers of the fungal isolate pathogenicity on the strain level.
