PSEUDOSYMMETRY OF THE LEAF BLADE SHAPE IN РОPULUS NIGRA L. UNDER INDUSTRIAL DUMP CONDITIONS
The article presents results of variability of pseudosymmetry index of the leaf blade shape in Роpulus nigra L. in different ecosystems. This index varied from 0,5485 to 0,9796. Leaf blades with indices of pseudosymmetry more than 0,9000 were typical for overwhelming part of analyzed samplings. The index values were significantly lower for the leaf blades of overburden rock dumps. We did not registered differences of index when compared sampling of Р. nigra blades of urban park with sampling of the blades of coalmine dumps. The index of pseudosymmetry of leaf blade shape was characterized by low variation (CV was less than 10,0%). Key words: wood plants, leaf blade, variability, Роpulus nigra L., pseudosymmetry, phytoindication
