Kurnyts'ka M. Special Features of Living Activity of Tree Species Under Urbogenic Conditions of Large Cities (Lviv consideration)

3. Tree species of city's plants subjected to urbogenic effect of various intensity. Complex evaluation of urbogenic factors and living activity of urban tree plants by selected set of crucial indexes characterizing photosynthetic apparatus and development of ecological compensating approaches to enhancement of plants biological strength. Ecological, morphological, anatomical, physiological, and biochemical investigations methods are used. Complex evaluation of urban environment factors and tree species' photosynthetic apparatus activity subjected to various levels of urbogenic loading is obtained. Criteria and evaluation scale for urban tree plants living activity are proposed. Procedures for improvement urban plants photosynthetic activity is developed. Application field is the system of urban afforestation.
