Some interactions of cadmium with other elements in plants. [Mn, Fe, Cu, Zn, Phaseolus vulgaris, Hordeum vulgare]
Cadmium in solution culture at 10/sup -4/M decreased Mn concentrations in bush beans (Phaseolus vulgaris L. C.V. Improved Tendergreen) at both low and high concentrations of Mn (noncompetitive inhibition). When Mn was decreased, the concentrations of Fe and several other ions were simultaneously increased, particularly in leaves and roots. Toxicity due to the 10/sup -6/ M Cd and the 10/sup -4/ M Mn was additive in the experiment. When barley (Hordeum vulgare L. Atlas 57) was grown in amended soil, 15 ..mu..g Fe as DTPA (diethylene triamine pentaacetic acid) per g soil resulted in increased uptake of Cd and in somewhat greater yield depression for soil pH of 3.9, 6.0, and 7.6. Acidification of soil without DTPA also increased Cd uptake to high levels with associated yield decrease. The Cd decreased the uptake of Mn and Cu most when CaCO/sub 3/ had also been added to the soil. When salts were added to soil with Cd before bush beans were grown, KCl (200 ..mu..g K/g soil), and equivalent KH/sub 2/PO/sub 4/ increased Cd concentrations of leaves while CaSO/sub 4/ and KCl did so for roots. In bush beans with different levels of Cd and Zn, there were no yield interactions, but some interactions of Cd on Zn concentrations in leaves, stems, and roots at the high Zn level.
