Regional distribution and ecological-phytocenotic description of dominant plants of Southern Uzbekistan

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