Abstract
The effect of Zn, Cd and their combination on Ca, Fe and Mn uptake by wheat seedlings was studied with solution culture. The result shows the Zn and Cd contents of wheat increased with increasing concentrations of Zn2+ and Cd2+ in solution, while there was a difference between single and compound treatments. Zn affected Cd uptake by wheat, and Cd inhibited Zn uptake. The uptake of Ca and Mn reduced with the increase of Zn2+ and Cd2+ in solution. The uptake of Fe increased with increasing Zn2+ and Cd2+ concentrations in single treatment, while decreased in compound treatment. The interactive effect of Zn and Cd was also related to the parts of plants.
