Structural restructing of the sheet apparatus Betula pendula Roth on the dumps of the coal mining industry

Provides information about the anatomical and morphological rearrangements of the leaf apparatus of birch in the conditions of the waste dump of the Kedrovsky open-pit mine of the Kemerovo region. The reorganization of the morphological structure of the leaf consisted in reducing the size of the assimilation surface of hanging birch. Anatomical rearrangements of the lamina were manifested in a decrease in the power of photosynthetic tissues (mesophyll) and the upper epidermis, and an increase in the height of the cells of the lower epidermis. The results of the correlation analysis showed that under the conditions of the waste dump, there was a greater number of reliable correlations between the anatomical and morphological indicators of the structure of the birch leaf, and this was due to the formation of positive correlations.
