Abstract

Studies were conducted on the water content in day and seasonal dynamics in the leaves of 4 species of halophytes and xerophytes growing in arid conditions of Tajikistan. It is shown that in the leaves of the camel thorn the amount of water in May during the day varies from 61.3 in the morning to 70.8% at noon. In leaves of wormwood Fergana in May, the water content in the morning and evening was almost the same, and at noon it was lowered. From the middle of summer to the end of August, the waterlogging of the leaves of camel thorn and Fergana wormwood decreases. With the onset of autumn, the water content in the leaves of camel thorn and wormwood Fergana was elevated. In the leaves of the hydrochloric bath of Belianje and the tamarix of the multi-branched and the water content was high both in the daytime and in the seasonal dynamics. Thus, the results of our studies revealed that the water content in the leaves of the plants we studied varies several times during the day and also changes in seasonal dynamics, due to this, these plants possess resistance, plasticity and adaptability to stressful growth conditions.
