Abstract

The results of a comparative analysis of the annual radial increment in two stands of Scots pine (Pinus sylvestris L.) are presented in the article. One of the trial plots is adjacent to the industrial dumps of the Uchalinsky Mining and Processing Plant, which pollute the environment with a complex of industrial pollutants with copper and zinc dominating among them. A nearby stand with trees without symptoms of direct exposure to industrial pollution was selected as a control. As a reference point for determining the dynamics of annual radial increment, 1959 was chosen when the Uchalinsky quarry began to be actively established. Despite the exposure of the trees on the territory of the plant to significant industrial pollution, a significant and increasing decrease in the values of annual radial growth was not observed among the trees of this trial plot. At the same time, the coefficient of variation of the increment in each year of measurements was consistently lower on this habitat compared to natural conditions. The results obtained were explained by the ecological plasticity of Scots pine and its tolerance to the toxic effects of copper and zinc. The data also prove the necessity of using the species for the natural remediation of industrially polluted territories and the accumulation of heavy metals in biomass of trees.
