Kinetics of magnesium uptake by rice plants

N. K. Fageria1
1 Faculty of Agronomy, Catholic University of Louvain, Belgium

Uptake of magnesium was studied by continuous flow technique for 82 days old rice plants in nutrient solution over a range of 0.2 to 1 ppm or 8.2 to 41 µM magnesium concentration. Uptake of magnesium followed a Michaelis-Menten kinetics with a Michaelis constant, Km of 0.2 × 10-4M and Vm 156 µg g-1 h-1. With increasing flow rate, the rate of magnesium absorption was increased.
