Abstract
This article analyzes the results of the research conducted by scientists in the study of plants of the region. Taking into account the laws of the distribution of plants in the regions, the dominant plants of the desert, hill, mountain and pasture regions of South Uzbekistan are given an ecological and phytocenotic description. In particular, the results of the expedition conducted to study the plants distributed in each region, and the results of experimental research are highlighted. According to it, information on the Latin name of plants, ecological status, distribution according to soil types, dominance characteristics, communities is provided. The formation of vegetation cover specific to the climate of each region was analyzed. In particular, dryness (lack of moisture) and high temperature for the desert determine unfavorable climatic conditions for plant life. Here, the shortness of the growing season of plants, mainly due to the lack of precipitation, early drying of the soil, often determines the summer and winter dormancy of two dormant periods in the seasonal development of plants. Despite the fact that desert conditions are unfavorable for plants, it is possible to observe their diversity during the seasonal vegetation period. Adir is located between a barren desert and a mesothermal mountain, and according to the living conditions of the plants, the stage part is arid, and the upper part is close to the mountain.
