Phytocenotic features of species of the genus Salsola L. (Chenopodiaceae Vent. / Amaranthaceae Juss.) in the desert part of the Syrdarya river valley

Abstract

The study of species of the genus Salsola L. in the desert part of the Syrdarya river valley (Kyzylorda region) is of great importance for identifying the features of the structure of phytocenoses in this region, which will facilitate rational use of plant resources and make recommendations for the radical improvement and recultivation of pastures in this territory. Various phytocenoses are confined to this territory, including those with the participation (dominance) of species of the genus Salsola L. Classical botanical methods were used in the research process. Fundamental floral summaries were used to identify the collected material. Vegetation was studied applying traditional methods of field geobotanical research. According to the results of the expedition work in the desert part of the Syrdarya river valley, 24 plant communities were described with the participation and dominance of species of the genus Salsola L. The communities differed from each other in the composition of the species. This is due to the diversity of the combination of environmental factors: natural physical and geographical and anthropogenic. The 24 communities represented can be divided into two groups: 1) communities dominated by species of the genus Salsola; 2) communities containing species of the genus Salsola. As a result, it was found that the annual species of the genus Salsola: S. nitraria, S. paulsenii and S. tragus are well adapted to the habitat conditions in the study area and can be used in reclamation work in desert zones.

Characterization of the Plastid Genomes of Four Caroxylon Thunb. Species from Kazakhstan

“…The Chenopodiaceae family encompasses approximately 1700 species distributed among around 110 genera [3]. Ecologically, representatives of the Chenopodiaceae family play crucial roles in desert ecosystems, serving as vital food sources for herbivores and contributing significantly to soil stabilization [4]. One of the family's largest and most important tribes is Salsoleae s.l.…”

“…According to POWO (Plants of the World Online) [10], the genus comprises 128 species globally, with nine of them found in Kazakhstan. These species are economically significant as forage plants and sources of medicinal compounds [4,7].…”

Peculiarities of species composition of phytocenoses with dominance and participation species of the genus Salsola L. in desert and semi-desert regions of Kazakhstan

“…Ряд представителей семейства (Asteraceae, Fabaceae, Tamaricaceae и др. ), являясь доминантами и эдификаторами многих пустынных сообществ, играют важную роль в сложении растительного покрова (Курочкина, Оспанова, 1973;Курочкина, 1978;Курочкина и др., 1984;Осмонали, 2021;Osmonali et al, 2022).…”

“…Кроме того, они обладают значительным полиморфизмом и сильной возрастной изменчивостью. Поэтому многие роды и в настоящее время остаются недостаточно изученными (Osmonali et al, 2022).…”
