Taxonomic Analysis of the Hydrophilic Flora of the Samarkand Region (Uzbekistan)

Abstract

Aquatic and coastal aquatic plants are one of the most important components of aquatic ecosystems. Therefore, much attention is currently being paid to the issues of rational use and development of the country's inland water bodies. Together with phytoplankton, this group of plants participates in the trophic cycle of the biocenosis, providing the corresponding products with different stages of the links of the food chain. For example, pond plants serve as food for representatives of different systematic groups of animals, mollusks, crustaceans, insects, fish, birds and mammals. The article presents the results of studies on the study of water and coastal plants of water bodies in the Samarkand region. It was revealed that in the water bodies of various types in the territory of Samarkand region 72 species of aquatic and coastal plants grow, which belong to 51 genera, 32 families and 5 classes. Representatives of the families Potamogetonaceae, Poaceae, Cyperaceae and Polygonaceae make up 43% of the total number of plants of this group growing in the studied region. According to life forms, about 12.5% (9 species) are annuals, and 77.8% (56 species) are perennials. It has been established that 7 species of water mosses grow in the studied reservoirs.
