The role of individual components in tea plant (Сamellia sinensis (L.) O. Kuntze) antioxidant system in adapting to stressors of an abiotic nature

Abstract

the paper presents an ecological and physiological assessment of plants used in urban landscaping, among the leading structure-forming species by the analysis of the leaf apparatus. Plants growing in urban environments were recorded to have deterioration in the morphometric characteristics. there was a variation in indicators during the growing season (V = 2-14 %), depending on the type and place of growth. the coefficient of fluctuating asymmetry in leaves from the conditional control zone corresponds to the first score; in the stress zone, the environmental situation varies from relatively clean to dirty. In the leaves, there is a slight increase in the stomata density and their length changes significantly in species growing in the areas of main plantings.
