Abstract
Rice was germinated and grown above distilled water in the dark at 27-30 degrees C. After 2-3 weeks, the seedlings were grown in water-cultures. Addition of glutamate to the cultures increased K uptake. Krebs-cycle acids had no effect on K uptake, but increased NH4 and P uptake. Acetate and glycolate, within 3-10 mM concentrations, considerably increased K uptake but had little effect on, or depressed, NH4 and P uptake. K uptake was reduced in P-deficient seedlings.
