The influence of heavy metals ions on growth and physiological and biochemical reactions of the sand and water cultures moss Drepanoclaus aduncus (Hewd.) Warnst.

Abstract

The influence of ions of heavy metals on regeneration ability of shoots, intensity of the chlorophyll luminescence, on the content of TBA-reactive substances and superoxide dismutase activity has been investigated in sand and water cultures of the moss D. aduncus. It has been shown that the tolerance for heavy metals action depended on growth conditions cultures, kind and concentration of heavy metals, however. The concentration of the metals being increased, the intensification of freeradical oxidation and weakening of adaptive ability took place.
