Affecting factors of soil rock dumps at the action of heavy metals and acidity on colza plants

Abstract

Іndicators of growing, changes in content of photosynthetic pigments, hydrogen peroxide, and activity of peroxidase in growing plants of colza were studied regarding negative influence of and soil components of rock dumps of coal mines. It was shown that heavy metals possess the most negative influence on the morphological and physiological indicators, and their influence is increasing with elevation of acidity. Decrease in content of hydrogen peroxide and increase in the activity of peroxidase suggests the activity of protective mechanisms in the growing plants of colza.
