The characteristics of cenopopulations and peculiarities of leaf mesostructure Orthilia secunda L. on the disturbed industrial lands

The results of study of age, morphological and spatial structure of cenopopulation Orthilia secunda L., mezostructure of the photosynthetic apparatus and type of mycorrhizae in plant communities in various technogenic substrates are presented in this paper. It is shown that in disturbed industrial lands, Orthilia secunda L. changes its morphology and its mezostructure parameters (decreasing in leaf thickness, size of chloroplasts, internal assimilation surface mezophyll and chloroplasts) compared with natural habitats.
