Physiological and biochemical effects of heavy metals stress on plant root system and chlorophyll of two species of lawns were tested The results showed that cadmium and lead concentration in the nutrient solution could inhibit the contents of hydroxylamine and enzyme activity of superoxide radical, it would been dropped the plants root quantities and the leaf chlorophyll The results indicated that cadmium had stronger effect to the leaves than lead, but the lead had stronger effect to the roots than cadmium When heavy metals had been inhaled into mesophyll, it could raised the contents of superoxide radical and caused chlorophyll dropped The effect of the cadmium pernicious to creeping bent was greater than that of perennial ryegrass
