RESEARCH OF THE STATE OF WOODY AND BRUSHWOOD PLANTS UNDER ANTHROPOGENIC STRESS CONDITIONS

Objective. The study of anthropogenic impact on environmental components, primarily woody and shrub plants, which are the main medium-forming element in natural artificial ecosystems, is relevant. subject this was ecological biological state plants under conditions technogenic stress.
 Materials methods. article presents results a life plants. For this, test plots were laid territory sanitary protection zones industrial enterprises plantings plantings. quantitative content tannins polyphenol oxidase plant leaves during active growing season determined by spectrophotometry titrimetric analysis.
 Results. Vitality decreases following order: Betula pendula Roth.> Sorbus aucuparia L.> Rosa majalis Herrn.> Acer negundo Tilia cordata Mill. In plantations territories, an increase damage to leaf blade noted, greater number dry branches appear crown tree, compared control zone. Thus, area, lowest scores recorded Mill., And highest vital silver birch. mountain ash, wild rose American maple, average. activity observed consequence intensive load Increased helps decrease leaves. Roth. L. SPZ July, accumulation more intense than plantations.
 Conclusion. Roth., plantations. Spectrophotometric determination understand reasons why increases or decreases. This fact indicates participation complex adaptive reactions associated with from aerogenic pollutants. As result study, most resistant stress species identified: birch, cinnamon rose, rowan tree.
