Summary Response of corn to Zn and Cu on a salinized soil in pots has been studied. Zinc increased the dry weights of tops and roots at all levels of NaCl+CaCl2. Increasing Zn level increased the weights considerably at 10 mM NaCl+CaCl2. Copper increased the weight of tops at 10 mM NaCl+CaCl2: it had little effects on plant weights at 50–125 mM NaCl+CaCl2. The growth response of plant to low Cu was somewhat similar to that of higher Zinc. NaCl+CaCl2 treatments, in general, increased Zn concentrations in tops as well as roots. At low Zn application, Zn concentrations in the tops were higher than those in the roots but at high Zn application, the concentrations of Zn in tops were similar to those in the roots. NaCl+CaCl2 treatments increased Cu concentrations in the tops to a slight extent but had a depressive effect on those in the roots. Copper concentrations in the tops were, however, much below those in the roots. The greater retention of Cu in the roots remains to be explained.
