Environment pollution with heavy metals is becoming more im-portant these days. In this work we investigated the impact of soil con-taminated with various concentrations of two heavy metals Cd and Cu (100; 200; 400; 800 and 1 600 mg/kg soil) on barley (Hordeum vul-gare) growth and bioaccumulation. Investigated plants were sown in vegetative pots with the prepared peat and sand substrate (ratio 2:1), and 4 days after germination the plants were watered with appropriate metal concentration solutions. The experiment lasted for 14 days until the second true leaf unfolded. At the end of the experiment, the con-tent of pigments was measured using a spectrophotometer, MDA was determined using the thiobarbituric acid method, and plants height and dry mass were also detected. Increasing of metal concentrations decreased plant height and biomass, and the Cd effect on morphologi-cal parameters was higher than that of Cu when a correlation between barley height and Cd concentration was –0.74 (p < 0.05) and betwee
