Structure and floristic composition of subalpine and alpine cenoses of Baghdati and Vani districts

Abstract

Plants of alpine belts are adapted to winter frosts, long snow cover, strong winds, direct light with great intensity, strong transpiration, short vegetation period. Cenoses of subalpine grasses are not characterized by lying fallow, at the same time they have a peculiar structure and floristic composition.The development of this vegetation is related to soil moisture, rich humus content, solar radiation and lighting, which are optimally presented here.A considerable amount of light, precipitation and heat in these zones promotes vigorous plant growth and leads to the formation of large,  broad-leaved and multi-flowered plants.The article discusses the vegetation cover of subalpine and alpine belts (trees, shrubs, shrubs-grasses, grasses) of Baghdati and Vani districts, the influence of soil-climatic factors in their morphological and anatomical structure. The main routes of plant collection at different times of the year are described:Tsiteli Mindori (Red field), Sairme crossing, upper Sulori river area, Kenchsakari, Naduknevi, Lamazi Gori, Sakondakhestsveri. 255 species of plants were collected, including 82 species from typical subalpine and alpine belt. Other species are also found in the upper belts of the forest, in small numbers - further down.
