Physiological features of toleranceof the main species of blooming lawns in the urban environment

Abstract

The activity of enzymes of the antioxidative complex and glutathione-ascorbic acid system of the main species of decoratively-flowering plants used for blooming lawns in the urban environment are determined. The activity of catalase, peroxydase and polyphenoloxydase, and the content of glutathione and ascorbic acid in 13 plant species were analyzed. One of the basic criteria of plants tolerance is the level of prooxydative and antioxydative metabolic processes. The plant species resistant to adverse conditions are recommended for use in the blooming lawns design in industrial cities.
