At the same time, under the circumstance that the natural area is directly getting smaller, the necessity and relevance of the thesis work on the evaluation of species’ natural reserves and the evaluation of the modern situations are demonstrated through examples. The Surkhandarya region is considered to have the largest number of plant species in Uzbekistan, and it is also distinguished by the variety of species. According to the location of the botanical-geographical regions of Uzbekistan, the territory of the Surkhandarya region is divided into five botanical-geographical regions (BGR). The 5 × 5 km2 grid system map includes 882 cells. Surkhan-Sherabod (BGR), Baisun (BGR), Sangardak-Topalang (BGR), Babatag (BGR), and Kuhitang (BGR) corresponded to these. Simultaneously, the 5 × 5 km2 grid system map of Uzbekistan’s flora in the Surkhandarya region revealed the presence of F. tadshikorum in 109 indices. On the territory of the region, the botanic-geographic region mainly includes the F. tadshikorum, Babatag (BGR), Baisun (BGR), and Kohitang (BGR) indices. The natural resources of F. tadshikorum in these areas were also analyzed.展开更多

The article presents the place of Aegilops triuncialis L. in plant communities and the status of populations in the flora of Uzbekistan. The research was carried out in various botanical and geographical regions of Uzbekistan during 2021-2023 years. During the research, the existing literature and geobotanical records, samples stored in the Institute of Botany (TASH) fund, and data on the GBIF international website were analyzed. Based on literary sources, more than 100 local points were recorded. The vitality structure of 11 cenopopulations was studied during field research. Various abiotic and biotic factors influencing the state of populations were analyzed. The main cenopopulations of the species were observed to spread in various grassy shrubland communities.展开更多

According to the results of the study, it is proved that the main distribution of the species coincides with the boundaries of the areali Tien-Shan mountain system (Uzbekistan, Kazakhstan). It is noted that the climatic factors that are optimal for the species are sufficient temperature and annual precipitation.展开更多
