Summary
Certain cations were added to nutrient solution cultures, in which intact bean plants were being grown, in an attempt to establish whether they influenced either entry of radiozinc (Zn*) into these plants or translocation of this element from the roots to the tops, or both. The Zn*-level in the culture solution was maintained at 5µM and the concentrations of the added cations were varied from zero through 60µM in the highest treatments.
When copper was present as the added cation at the Zn*-level (5µM), Zn*-uptake was severely reduced but internal translocation was not especially altered.
When zinc was present as the added cation it exerted the expected competition on Zn*-uptake and in addition exerted an unexpected, suppressing effect on Zn* being translocated to the tops.
Manganese, as an added cation, has an effect on Zn*-uptake only at high concentrations (30µM or more) but it did not alter the internal Zn* distribution.
Cadmium behaved similarly to copper in its influence on Zn*-uptake and translocation.
It is concluded that the general effect of added cations on Zn*-uptake and translocation in intact bean plants is predominantly to inhibit uptake, not internal distribution.
