Comparative investigation of natural and anthropogenic stress influence on plants

Comparative analysis of plant reaction on natural (high mountain environment) and anthropogenic (heavy metals contamination) stress was done on the basis of studying of some morphological and physiological characteristics. The study revealed that both stresses lead to reduced fertility of plants, which is accompanied by an increase in the mass of seeds. Contradistinction of anthropogenic stress is the decrease germination and the change in energy of germination of seeds, which is characteristic for a toxic influence.
