Abstract
The anatomic-morphological indicators of the needles of Picea obovata Ledeb. under the effect of emissions from the industrial zone of Kemerovo were investigated. Some changes of the negative nature were detected: a reduction of length, area and the surface of pine needles, the thickness of the inner lining and epidermis, an increase in the asymmetry of the central conducting beam, a reduction of the number of pitch channels. Some changes of the adaptive nature were also detected: an increase in the thickness of epidermis and endodermis, an increase in the area of pitch channels and the central cylinder. The significant correlation of the complex index of atmospheric pollution with the anatomic-morphological characteristics of pine needles was revealed. This confirms the fact of the substantive effect of emissions from the industrial zone of Kemerovo on the anatomical structure of pine needles of Picea obovata Ledeb.
