Abstract

The article presents the results of studies of the features of the white-rot and brown-rot fungi development on Querqus robur stems. 34 trial plots in 13 forestry institutions of the republic located in different geobotanical subzones were created during the study. The height of the location of tinder mushrooms was measured on 362 trees. It is noted that the height of the location of the Phellinus robustus is from 0.4 to 16.5 m, Laetiporus sulphureus – from 0.65 to 12.1 m.

18 model trees were analyzed to obtain information on the shape and extent of the rot. It was found that the main points of Phellinus robustus and Laetiporus sulphureus penetration are dead twigs (54.5%) and frost cracks (57.1%) correspondingly. Length and intensity of white and brown rots development along the trunk section are increasing with an increase in soil moisture, and with an increase in soil richness these indicators, as well as the number of formed fruit bodies, are decreasing.
