The Interaction between Cd and Zn in Roots of Tall Fescue After 15 days of Cd treatment, the Cd concentration in the roots of tall fescue decreased by more than a half with the increase of Zn concentration in the nutrient solution ( Figure 2 a), while Zn concentration in the roots showed a decreasing trend with the increase of Cd concentration, indicating that Zn and Cd acted antagonistically to inhibit their uptake in roots of tall fescue.
