EVALUATION OF THE INFLUENCE OF SOIL PARAMETERS OF TECHNOGENIC TERRITORIES ON THE VARIABILITY OF THE LEAF BLADE OF POLYGONUM MONSPELIENSE THIÉBAUT EX PERS.

Geometric morphometry methods were used to evaluate the influence of a number of soil parameters in technogenic territories on the variability of the leaf blade of Polygonum monspeliense Thiébaut ex Pers. under laboratory growing conditions. According to the results of the correlation analysis, out of the seven analyzed soil parameters, the manifestation of variability in the shape of the leaf blade is most affected by the content of humus and nitrate nitrogen, and the manifestation of fluctuating asymmetry is the hydrolytic acidity of the soil. The content of mobile phosphates and exchangeable ammonium in the soil does not have a significant effect on the considered morphological parameters of the leaf blade.
