Calcium deficiency and CaCO/sub 3/ on micronutrient status of plants grown in solution culture. [Lycopersicon esculentum, Phaseolus vulgaris]
Plants were grown in solution culture with different levels of Ca to further evaluate Ca relationships to trace metal uptake and to toxicity of trace metals. When tomato plants (Lycopersicon esculentum L., Tropic) were grown at a low level of Ca, the Zn, Cu, Fe, Mn, Al, and Ti concentrations of leaves, stems, and roots were considerably increased. The use of an excess of CaCO/sub 3/ which increased pH did not influence the trace metal concentrations of plants any more than did Ca/sup + +/. In a factorial experiment with bush beans (Phaseolus vulgaris L. C.V. Improved Tendergreen) with Ca (10/sup -4/, 10/sup -2/, 10/sup -2/N) and Ni (0, 2 x 10/sup -6/ M, 2 x 10/sup -5/ M), Ni phytotoxicity and Ni uptake were decreased somewhat at the highest Ca level. High Ni tended to decrease the Ca concentration in leaves. High Ca and Ni both tended to decrease Fe, Cu, Zn, and Mn concentrations in leaves. The Ni had some interactions on the P concentrations of shoots.
