System of morphological characteristics of the woody plant lamina in different ecological conditions on the example of the types of black poplar and white willow

The research was conducted in the period from 5 to 12 September 2011 at the territory of the Chelyabinsk region in three areas: the first is the Iskra settlement, the second is in the Gagarin Park in the North-West district of Chelyabinsk city and the third is the Lineynaya Street of the Traktorozavodskoy district. The object of the study is species of woody plants of the Chelyabinsk region: white willow (Salix Alba L.), black poplar (Populus nigra L.). The aim of the work was the establishment of regularities of the change of wood plant lamina characteristics in different ecological zones of the Chelyabinsk region. The obtained results were subjected to special processing using the developed algorithm, containing more than 20 statistical methods, including multi-dimensional method, using a package of programs Statistica, SPSS and Olympus - expert. The analysis of differences between woody plants showed that there is common regularity of intraspecific and interspecific differences. That is, at increasing the degree of anthropogenic load decreasing of the diversity of responses and specialization of the existing ones takes place. At further deterioration of the ecological condition the reaction of trees remains unchanged. In the case of worsening growing conditions of the reaction of woody plants is a reduction in the diversity of responses in the direction of increasing specialization of the existing ones. The result of the analysis of the contribution of the leading factors to the variability of the lamina showed that the maximum influence is produced by combined activity of the environment state and wood plant species specificity.
