Mechanism of uptake and translocation of zinc by pea plants (Pisum sativum L.)

Summary Radiotracer studies revealed that the mechanism of zinc uptake was not purely non-metabolic. The over all uptake of Zn by intact plant ofPisum sativum L. (Var. T-163) occurred through an initial nonmetabolic phase followed by a metabolically mediated absorption. The translocation of zinc from plant roots to shoot was more sensitive to metabolic inhibitors and thus was a metabolic function.Research Publication No. 1541/116/0 through Experiment Station, G. B.
