Abstract
A study has been made of the kinetics of K accumulation by corn and soybean roots as affected by Ca. For both kinds of roots, Ca increases the affinity between the K ion and the postulated carrier; in a second reaction, independent of the first, Ca decreases the velocity of the metabolic phase of K uptake. The first effect of Ca is proportionally greater in corn, while the second is proportionally greater in soybeans. The net result of the two effects is to reduce maximum K accumulation in the presence of Ca more in soybeans than in corn.This publication has 12 references indexed in Scilit:
