K.  aKinetics of magnesium uptake by rice plants.  c1976  aUptake 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.  aMagnesium  aRice  aArroz  aMagnésio  aOryza Sativa  tBiologia Plantarumgv. 18, n. 3, p. 169-172, May 1976.
