Abstract
The effect of exogenous NH4+ on NO3− uptake and in vivo NO3− reductase activity (NRA) in roots of Phaseolus vulgaris L. cv Witte Krombek was studied before, during, and after the apparent induction of root NRA and NO3− uptake. Pretreatment with NH4Cl (0.15-50 millimolar) affected neither the time pattern nor the steady state rate of NO3− uptake.This publication has 18 references indexed in Scilit:
