For the first time in Azerbaijan, differences in the morphological parameters of oak trees growing in different regions have been determined, the agrochemical properties of soils under oak trees have been studied, and the influence of environmental pollution on tree leaves has been shown. In different regions of Azerbaijan, morphological polymorphism, caused by the influence of various environmental factors, is different in oak taxa. The level of intrapopulation polymorphism established by dispersion analysis is higher than that of traits with the greatest diversity of variability N (YU/YE) (CV = 111.01%), F (CV = 54.11%) and YS (CV = 35 . 01 %). The Jaccard similarity coefficient is 0.334 with a significant variation of genotypes from each other of 0.827, which indicates its difference in degree and adaptability in the studied taxa. The asymmetry index we calculated (coefficient of fluctuating asymmetry) for Q. petraea sp. and Q. robur sp. equal to 0.067 is considered a conditional norm. The highest indicators are typical for Q. petraea sp. both in areas with intense traffic flow and in the territory of the botanical garden. For Q. rubra, the highest coefficient of fluctuating asymmetry was noted in the botanical garden. The stomal fissure width and stomal fissure length of leaves Q. robur L. and Q. rubra L. are high in the area of Absheron Garadag highway. Intensity of damage to oak leaves spotting and rust high level are registered in Absheron Garadag highway region. Indicators obtained through scientific research are conveniently used in preliminary forecasting as a non-invasive test that protects the principles of green technologies, without involving other more complex tests that require financial and labour resources, such as an indicative test that is sensitive to small changes within a plant organism.
