ANALYSIS OF PHYTOINDICATION PROPERTIES OF ROBINIA PSEUDOACACIA L. IN THE CONDITIONS OF KAMYANETS-PODILSKY

Phytoindication properties of Robinia pseudoacacia L. in the conditions of Kamyanets-Podilsky were analyzed. Data on the role of plants in the ecological stabilization of the urban environment are given. It is noted that woody plants have a number of advantages over others, as they enrich and purify the air throughout the year, their large area of photosynthetic organs allows you to effectively absorb toxic substances from the environment and play an assimilative role. In addition, woody plants are studied in phytoindication studies. Information about the object of study, its contradictory significance due to invasiveness and large economic and social role is provided. To analyze the phytoindication properties of R. pseudoacacia in the conditions of Kamyanets-Podilsky, we selected seven experimental sites with different anthropogenic loads, including traffic intensity. The area of leaves, the number of beans on the model branch, the length and width of the beans, the morphometric parameters of the seeds (length and width), the number of seeds in the bean and the weight of the seeds were chosen for the studied parameters. It is shown that R. pseudoacacia plants in different places of growth of KamyanetsPodilsky differ in morphometric parameters. It was found that with deteriorating conditions, the area of leaves, the number of fruits on the model branch, the length and width of beans, seed weight and its linear size decreases. We propose to use the studied parameters in bioindication studies to assess the state of the environment.
