Triticale exposed to different concentrations of Cu, Cd and their combination for 6 days in aqueous culture were analyzed with referance to the accumulation of biomass in root and leaves. Treatment with different concentrations of them, affected the accumulation of plastid pigments. The application of 500 g m-3 biomin to Cd and Cu treated plants brought an increase in the ratio chlorophyll a or chlorophyll b, and an decrease in the ratio chlorophylls carotenoids. An enhaced lipid peroxidation and an increased tissue concentration of hydrogen peroxide in both roots and leaves indicated that Cd and Cu caused oxidative stress in triticale plants.
