Analysis of phytopathogenic micromycetes common in fruit trees and shrubs (the city of Samarkand as an example)

Abstract

The study identified phytopathogenic micromycetes common on fruit trees and shrubs. The article was prepared on the basis of mycological analysis of herbarium data collected during planned expeditions. They grow Cydonia oblonga, Malus Domestica, Vitis vinifera, Prunus cerasus, Prunus persica, Prunus Armeniaca, Prunus Domestica, Diospyros kaki, Elaeagnus angustifolia, Crataegus turkestanicum, Morus nigra, Juglans regia, etc. During the expeditions it was noted that that the above host plants are damaged by the orders Helotiales (10 species), Venturiales (6 species), Mycosphaerellales (4 species) and Pleosporales (4 species). Also identified were 2 species belonging to the orders Diaporthales and Botryosphaeriales and Pucciniales, and 1 species each belonging to the orders Dothidiales and Taphrinales. The article contains detailed information on the results of mycological and taxonomic analysis, host plants and phytopathogenic fungi. This information will be useful when compiling. As a result of morphological and microscopic analysis of the collected herbarium samples and analysis of the literature, it was established that 32 species of micromycete fungi are found in 18 plant species and are pathogenic. As a result of the analysis, it was established that 32 species of micromycete fungi belong to 2 sections, 5 classes, 9 orders, 15 families and 25 genera.
