Bioindication parameters Quercus pubescens Willd in natural forest phytocenosis and in areas affected by road traffic

The paper presents the results of research on individual stable development and accumulative capacity of leaves of the species Quercus pubescens Willd. growing in natural forest phytocenosis and in areas affected by road traffic on the territory of the Khachmaz region of the Republic of Azerbaijan. The study areas differed in the degree of environmental pollution. The assessment was carried out with the aim of further using this plant for rapid assessment and quality management of the environment in the Republic of Azerbaijan. To assess changes in the stability of leaf development, a method of fluctuating asymmetry was used. The accumulative properties of fluffy oak were investigated by elemental analysis of leaves and soil. The analysis of microcomponents in samples of leaves and soils was carried out on an X-ray fluorescence spectrometer. As a result, it was found that with an increase in the level of anthropogenic influence, the level of phenotypic changes, morphological signs of leaves, and their accumulation of elements increases. Accordingly, there is the prospect of using oak fluffy as a natural filter for cleaning and environmental quality management.
