Dynamics of water regime of Tilia cordata leaves in technological conditions

Abstract

The paper is devoted to studying water regime of Tilia cordata in the conditions of petrochemical pollution of the Ufa industrial center. Water regime was studied in both different conditions of pollution and geomorphologic conditions (watershed plateau and flood plain) and in stands of all age classes as well. The study of water regime was carried out in the field during the growing season using the method of rapid weighing. It is shown that the leaves of Tilia cordata are characterized by high values of relative water content. At the same time the intensity of transpiration is variable depending on various factors. The stability of water regime is an important indicator of broad adaptability of Tilia cordata to technogenesis.
