The effect of phosphorus (P) starvation on ammonium (NH4) uptake was evaluated by growing single-cross seedlings of the make progenitor of the maize double-cross hybrid BR 201 in nutrient solution. The kinetics of NH4 uptake were measured after P starvation and non-starvation periodo of 2, 4, 6, 8 and 10 days. The effect of P addition during the study period (resupply) was also tested. Ammonium uptake decreased 45,7% after two days of P stress completed to the fully P-sufficient control. Ammonium uptake decreased 83,0% where P was withheld for 10 days. The decline in NH4 uptake was partially reversed when P was resupplied during the early periods of P deficiency, but this effect diminished as the P stress increased. These results suggest that maize plants are physiologically dependent on NH4, rather than nitrate (NO3) when under P stress. |
