Mutual toxicity of chromium and nickel sulphates for growth and development of maize plantlets was studied. Its combined action at low concentrations (10 –5 M) results to significant suppression of growth of both above-ground and root systems of maize . At the beginning of growth the greater negative effect of the salts mixture at high concentration (10 –4 M) was observed for the plantlets’ roots. Then, on the sixth day, the growth of above-ground and root system was inhibited equally. Application of high nickel concentration and low chrome concentration, in contrast to high chromium and low nickel levels, depresses the biomass gain. Meanwhile the length of roots and leaves was affected by both variants of concentrations identically.
