Toxic Effect Metabolites of Micromycetes Spread In Azerbaijan

Abstract

ABSTRACT: Annotation. In the research conducted, endogenous and exogenous metabolites of fungi were studied according to their toxic activity in different areas of Azerbaijan. It became clear that among the 46 species of fungi isolated from different areas, there are species with strong, medium and weak toxic activity, as well as species without toxic activity. 26,7% have strong, 56.6% have medium, and 10% have weak phytotoxic activity, but 6.7% do not have such an phytotoxic activity. None of the fungi belonging to the division Basidiomycota have either strong or moderate phytotoxic activity, only 50% of the remaining fungi have weak phytotoxic activity. All the fungi belonging to the Mucormycota division have a weak phytotoxic activity. Differences in the phytotoxic activity of fungi belonging to different taxonomic groups are related to the nature of their struggle in the environment they live in. So that, because the struggle for food of xylotrophic macromycetes takes place under conditions of weaker competition, their phytotoxic activity is characterized by relatively low indicators.
