Catalase activity in woody plants buds of Yoshkar-Ola waterfront

This article presents the study results to determine the catalase activity in the buds of woody plants growing on the waterfront of the Malaya Kokshaga River in the city Yoshkar-Ola limits. The most stable species are Aesculus hippocastanum, Crataegus sanguinea and Prunus maackii. Plants of Crataegus almaatensis and Acer platanoides 'Royal Red' were characterized by atypically high catalase activity, which requires further study of the indicator dynamics.
