Povorotnya M. Ecological and Physiological Stability Analysis of genus Acer in terms of anthropogenic conditions of Dnipropetrovsk thermoelectric power station

Object is the adaptation processes in maple plantations of urban phytocenosis in the Steppe Dnieper zone. The goal is to establish ecological and physiological characteristics of stability of maples species, their functions of phyto-soil reclamation under the impact of aerogenic pollutants from the thermal power plants, in particular - the most environmentally dangerous - of Pb and Hg; to estimate prospects of use of alien species of the genus Acer in the greening of urban areas of the Steppe Dnieper zone. Methods are ecological and biochemical, morphoanatomical, physiological, experimental, statistical, model experiment planning. The thesis is a quantitative assessment of toxic metals Pb and Hg as priority pollutants in the emissions from the thermal power plants of Dnipropetrovsk region on the example of the Dnieper and the Krivoy Rog TPP. It was determined sensitive test parameters of physiological state and metabolic activity of plants to indicate the degree of anthropogenic impact on the environment in a thermal power plant emissions in the condition of the Steppe Dnieper zone. It was developed the methodology for quantitative analysis of the genus Acer wooden aliens stability in the exotic collectible plantations in the botanical gardens and predicted their response to the impact of thermal power plant priority pollutants; on the basis of which it was assessed their capacity to attract cultural phytocenosis of the technological areas in the steppe zone. It was determined the degree of bioremediation properties of certain types of maple trees based on the accumulative ability, resistance to stress and the effects of hydrothermal Pb and Hg in the plant metabolism. There were suggested some recommendations on the use of new types of maple trees to enhance gardening in the anthropogenic contaminated areas and buffer zones. The research results are used in the research work of the Botanical Garden and the Department of Physiology and the Introduction of the Faculty of Biology of Plants, Ecology and Medicine in Oles Honchar Dnipropetrovsk National University in the teaching process of the following disciplines "Physiology and Biochemistry of Plants", "Physical Organization of Urban Areas", "Physiology of Plants Adaptation", "Phytoindication and Phytomonitoring of the Environment."
