GROWING PERIODS OF SOME GROUPS OF PLANTS IN THE FLORA OF SULAIMAN MOUNTAINS

Abstract

The article is devoted to the analysis of seasonal phenomena of some groups of lower (lichens) and bryophytes in higher plants found on Sulaiman Too. The purpose of the study is to assess the vegetative states of some groups of plants. It has been established that despite the arid climate conditions of the mountain, the studied groups of plants are quite rich. On rocky surfaces, lichens and bryophytes create unique associations, with bryophytes dominating. Unlike higher plants, the growing season of the studied groups of plants proceeds intensely in the winter-spring period and quickly ends. The intensity of their vegetation strongly depends on the amount of precipitation. The growing seasons of the studied groups of plants on the northern slope of the mountains begin 8-12 days later than on the southern slopes of Sulaiman Too. Тhe bryophytic and lichenophytic associations do not compete with those of higher plants, since they occupy only the surfaces of rocks.
