The modern species composition of the family Chenopodiaceae Vent. (Amaranthaceae Juss.) of the flora of the desert part of the Syrdarya river valley

Representatives of the Chenopodiaceae Vent. family are the hallmark of the flora of the desert regionsof Kazakhstan, as they far outnumber other leading families. Moreover, this applies not only to the flora of the mountainousterritories, but also to the flora of the river valleys, in particular, the flora of the wide valley of the Syrdarya river. Thepredominance of Chenopodiaceae is due to the excellent adaptability of its species to desert conditions. Quite a few speciesof Chenopodiaceae are dominant plant communities, especially in the middle deserts of the North Turan province. Amongthem there are many species that have useful properties (forage, landscape, medicinal, etc.). The aim of the work was toidentify the current species composition of the Chenopodiaceae family (Amaranthaceae Juss.) of the flora of the desertpart of the Syrdarya river valley. Classical botanical methods were used in the research process. As a result of the conductedstudies, the modern species composition of the Chenopodiaceae family of the studied territory, consisting of 112 speciesfrom 38 genera, was revealed. The three largest genera include genera: Salsola–17 species, Atriplex–15 species, Suaeda–11species. The remaining genera contain from 6 to 1 species. Genera represented by a small number of species predominate(26 genera of 1–2 species each).
