Flora and its analysis. Hydrophilic plants of different water bodies of the Samarkand region (Uzbekistan)

Aquatic and coastal aquatic plants are one of the most important components of aquatic ecosystems. Therefore, at present, much attention is 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 biocenosis, providing various stages of the links of the food chain with appropriate products. For example, the plants of reservoirs serve as food for representatives of different taxonomic groups of animals, mollusks, crustaceans, insects, fish, birds and mammals. With moderate overgrowing of water bodies, favorable conditions are formed for the development of the phytophilous fauna of invertebrates. The flora of higher aquatic and coastal plants of the Samarkand region has not yet been fully studied. The species composition was not studied, taxonomic and floristic analysis was not carried out. In addition, it is very rare to find detailed information about the use of aquatic plants in the national economy, information about useful species and rare species common in this territory. The article presents the results of research on the study of aquatic and coastal plants of reservoirs of the Samarkand region. It was revealed that 72 species of aquatic and coastal plants, which belong to 51 genera, 34 families and 5 classes, grow in reservoirs of various types on the territory of the Samarkand region. 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. In terms of life forms, about 12.5% (9 species) are annuals, and 77.8% (56 species) are perennials. It was found that 7 species of aquatic mosses grow in the studied water bodies.
