A study of the ascorbic acid content and activity of copper-containing enzymes in leaves of Sorbus aucuparia L. in the conditions of the Kama region

Analyzed the activity of copper-containing enzymes and content of ascorbic acid in the leaves of Sorbus aucuparia L., which is widely used in green spaces in the Kama region, which includes cit-ies such as, Yelabuga, Naberezhnye Chelny and Nizhnekamsk. Given the characteristic of the de-gree of air pollution in the studied cities. Identified changes in the activity of copper-containing enzymes and content of ascorbic acid in the leaves of Sorbus aucuparia L. during the vegetation period. The results obtained show that ascorbic acid and copper-containing enzymes are active par-ticipants in adaptation processes in a Sorbus aucuparia L. ordinary in the conditions of tech-nogenic stress.
