The assessment of the diversity of fungic communities and the study of the bioindicational significance of mycological parameters is relevant for the biomonitoring of ampelocenoses. We studied the quantitative and qualitative composition of saprotrophic micromycetes communities associated with annual shoots of wild and cultivated grape plants. Studies have shown that the number of saprotrophic micromycetes associated with an annual vine is different depending on the place of sampling and ranges from 232.9 … 3203.2 thousand CFU / g dry matter on wild grapes and within 118.9 … 344.1 thousand CFU/g dry matter on cultivated grapes. The highest density indicators of fungal populations - 1119.7 and 3203.2 CFU/g dry matter - were recorded on a vine from forest ecotopes, the lowest indicator of 118.9 CFU/g dry matter was recorded on a vine from ampelocenosis, On wild vines, major share in the studied of fungic communities was occupied by hyphal or mold fungi, on average their share was 95.1%, while yeast occupied 4.2%, and yeast-like fungi - 0.7% of the complex. On cultivated vines, hyphal fungi also occupied the largest part in the structure of fungic communities, but their share was 1.7 times less than on wild plants. Yeast (26.5%) and yeast-like fungi (18.4%) took much larger share.
