The article is devoted to the peculiarities of water regime vegetation dynamics of Tiliacordata assimilation apparatus in all age classes in the conditions of petrochemical and polymetallic pollution. It is shown that the leaves of lime trees in Ufa industrial center are characterized by high relative water content indices. At the same timein Sterlitamak industrial center there is a significant decrease in the degree of leaves hydration of the trees in the process of ageing. The transpiration rate in general decreases with anthropogenic impact levels increasing.
