Taxonomic analysis of phytopathogenic micromycetes of landscape trees and shrubs (based on the example or Samarkand city)

Abstract

The article provides information about phytopathogenic micromycetes of trees and shrubs common in the city of Samarkand. In the course of the research, it was established that 45 species of micromycete fungi are found in 32 plant species and are pathogenic. As a result of the analysis, it was established that 45 species of micromycete fungi belong to 3 divisions, 14 orders, 24 families and 28 genera. Herbarium data collected during the study were analyzed and it was found that 45 species of phytopathogenic micromycetes parasitize 32 species of host plants belonging to 28 genera and 21 families. The study identified 45 species of phytopathogenic micromycetes parasitizing 32 species of host plants. These 32 species of forage plants belong to 27 genera and 21 families, of which 21 species of trees and 11 species of shrubs were identified. Under the influence of fungal diseases caused by phytopathogenic micromycetes recorded in 32 species of ornamental trees and shrubs, the aesthetic properties of these plants decreased. Host plants were identified that were heavily infected with several species of phytopathogenic micromycetes.
