Abstract
The results of morpho-biological observations and biochemical indicators of decorative rhizomes of the genus Iris L. of the Iridaceous family growing in the conditions of the Kuzbass Botanical Garden are represented in the article. It was established the species-specifity in the duration of vegetation period and in the level of antioxidants accumulation of in leaves of decorative redivives:I. aphylla > I. halophile > I. chrysographes > I. ruthenica > I. pseudacorus. According to the results of the integral appraisal, all species are perspective for use in green building. The revealed restructuring in the functioning of the antioxidant system of irises allow considering them as adaptive and protective reactions aimed at their survival and decorative qualities in the environment. The studied figures can be used as an informative parameter to assess the plants condition in the introduction.
Highlights
Irises are the decorative flowering perennials its abundance in acсessible places of natural vegetation is significantly reduced
The following species I. ruthenica, I. chrysographes, I. pseudаcorus showed the highest number of points (90 – 94) on totality of decorative signs
According to the results of integral appraisal all the species shall be deemed as prospective for use in green building. It was established the species-specifity according to the duration of vegetation and the level of accumulation of antioxidants in leaves of decorative herbaceous perennials: I. aphylla > I. halophile > I. chrysographes > I. ruthenica > I. pseudacorus
Summary
Irises are the decorative flowering perennials its abundance in acсessible places of natural vegetation is significantly reduced. For the processes of adaptation of plants to new growing conditions, an ability to accumulate some secondary metabolites associated with the peculiarities of metabolic processes and the functioning of certain enzyme systems has the major importance [1 – 4]. The specific conditions of the vegetative period, caused by the continental climate of Kuzbass, contribute to the identification of the physiological-biochemical features of irises, which have a long decorative and reproductive capacity for their rational use in green building. The identification of the matching of the growing conditions of decorative herbaceous perennials to their biological needs within the conditions of the Kuzbass is very relevant
