Turbina I.N., Mantrova M.V., Kravchenko I.V. TOWARDS THE QUESTION OF THE INTRODUCTION OF LEATHER BERGENIA IN CONDITIONS OF KHANTY-MANSI AUTONOMOUS AREA — UGRAThe article is devoted to the analysis of some aspects of leather bergenia introduction in conditions of Surgut, namely, it considers the dynamics of photosynthetic pigments of chloroplast and heavy metals content in green leaves of bergenia at different stages of seasonal development. The content of green pigments in leaves varied during the vegetative period in the range from 0.58 to 0.69 mg/g with an accumulation maximum in summer months. Throughout the vegetative period gradual strengthening of the share of chlorophyll "a" was noticed, its level exceeded the level of chlorophyll "b" 1.5–3.0 times. The content of yellow plastid pigments throughout the entire period of research was considerably inferior to the level of chlorophyll. So, the maximum value of the share of carotinoids was 0.39 mg/g during vegetation. The assimilating bodies of bergenia participate in accumulation of chlorophyll, carotinoids, and low concentration of chemical elements indicates their main accumulation in fabrics of the root system. Thus, the content of photosynthetic pigments in green leaves of bergenia throughout the entire period of supervision varied with an accumulation maximum during vegetation. Low concentrations of the analyzed heavy metals at different stages of seasonal development are in green leaves of bergenia at the level, characteristic for uncontaminated places of growth. Specific features and differentiation of bodies of a plant to accumulation of these elements are also noted.Key words: leather bergenia, photosynthetic pigments, heavy metals, development phase.
