Abstract
Drought resistance evaluation of Ulmus L. genus species during the growing season by determining water loss by leaves by the method of laboratory wilting is carried out. This method is to determine moisture deficit and water-retaining ability of the leaves. Total and fractional water content, relative turgorescence and water deficit of plant leaves are determined. In particular, the content of associated water in most Ulmus genus species and forms exceeds the free water content by 2-4.5 times. The obtained result indicates a significant role of associated water in the plant adaptation to growth conditions. The total level of water loss by leaves varies from 52.1 % to 68.5 % with the predominance of high values of water content. Such indicators are an expression of adaptation mechanisms for tree plants that are evolutionarily adapted to arid conditions and are able to support physiological processes in case of a high level of water loss by tissues.
