For phytoremediation purpose it is essential to select an appropriate plant species which should be metal tolerant with high biomass production and known agronomic techniques. The aim of this work was to expand knowledge about protection mechanisms of sorghum plants under Cd and Zn stress. The metals accumulations in roots and shoots of hydroponically grown S. bicolor plants were studied. Our results showed that cadmium and zinc were accumulated primarily in the roots of sorghum plants. However, higher concentrations of the metals in the solution increased their transfer to the shoots. Toxic effects of metals in the shoots, especially at lower concentrations, were not so serious compare with their influence on the roots. When GSH was added, it significantly increased the accumulation of cadmium in the roots and also in the shoots (for the highest cadmium concentration).
