DISTRIBUTION AND ACCUMULATION OF HEAVY-METALS (CD, NI AND CR) IN TOMATO PLANT

Three experiments were carried out in soiless culture to determine the absorption and accumulation of Cd, Ni and Cr in different parts of to mato plant (Lycopersicon) esculentum Mill) and fruits. Those experimen ts showed the different behaviour of the metals. Cr was poorly transpo rted to aerial parts and was not detected in fruits. However Cd and Ni were more easily transported to stems+branches, leaves and fruits. Th e concentration of Ni was important in the fruits and it had no depend ency on the Ni concentration of the nutrient solution but Cd concentra tion in edible part was dependent on Cd treatment applied.
