Glibovytska N. Vitality and bioindication availability of small-leaved linden (Tilia cordata Mill.) in Ivano-Frankivsk urboecosystem.

The object is Tilia cordata Mill. planting of different functional zones in Ivano-Frankivsk urboecosystem. The aim is to assess the vitality and bioindication availability of small-leaved linden in the different functional areas of Ivano-Frankivsk urboecosystem. The methods are chemical analytical, visual, morphometric, physiological and biochemical, spectrophotometric, phenological, atomic absorption analysis, statistical. The peculiarities of heavy metals accumulation by small-leaved linden leaf plates and the level of pollutants soil contamination of different functional zones of Ivano-Frankivsk urbanized ecosystem are studied. The decrease of vegetative and generative organs morphometric parameters of Tilia cordata Mill. and worsening of the species sanitary condition in terms of anthropogenic pressure is set. The influence of the crown pruning on the terms of phenological phases of Tilia cordata Mill. species under urbanized environment conditions is found. The degree of correlation-regression dependence between the analyzed morphological, physiological and biochemical parameters of the type and the level of environmental pollution by heavy metals and dust is defined. For a set of analyzed parameters of Tilia cordata Mill. is found that the vitality of the species in the area of transportation routes and industrial complexes of urboecosystem is the average, in the area of residential development and integrated landscaping ? above average. The appropriateness of the investigated test parameters of Tilia cordata Mill. as informative features for assessing the ecological condition of urbanized and man-transformed environment is justified. Application spheres are bioindication, phytoreclamation, application courses.
