摘要

The purpose of this work is to study structural and functional characteristics of two plant species: Plantago media L. and Erigeron acris L., which grow on different technogenic substrates (ash and clay soil) in transformed habitats (ash dump of Verkhnetagilskaya State District Power Plant). We studied: the distribution of biomass, the parameters of the mesostructure of the leaf (the area and thickness of the leaf blade, the thickness of the mesophyll and epidermis, the volume and number of cells, the cell volume of the chloroplast, the cell membrane index, the percentage of mesophyll in the leaf), the total nitrogen content in the leaves, as well as arbuscular mycorrhiza. Species-specific changes in the studied biometric (distribution of biomass) and morphophysiological parameters (the size of the assimilating surface) have been revealed. On the ash substrate in Erigeron acris plants, a decrease in the size of the cells of the palisade mesophyll and, consequently, a decrease in the internal assimilating surface of the leaf were observed. At the same time, the properties of the substrate did not have a significant effect on this parameter in plants of Plantago media. The intensity of mycorrhiza formation in both species was higher on ash than on clay substrate.
