Rechevs'ka N. Adaptation of mosses to the toxic effect of heavy metals.

The dissertation is devoted to questions of accumulation of heavy metals in mosses and studing plants reaction on the toxic effect of heavy metals on the basis of plant physiological and biochemical, metabolic and growth processes. The levels of accumulations of cadmium, copper and lead ions by the different species of mosses were analysed. The new cytochemical method for the determination of heavy metals in plants was proposed. Dynamics of resistance of moss gametophyte dyring the ontogenesis was investigated. Stimulating influence of heavy metals on the electrophoretical patterns of proteins and enzymes was established. It was investigated the changes of activity of respiratory enzymes system, intra- and organization of metabolism in the cells under the influence of heavy metals.
