将双杂交杂种BR 201的雄性祖先的单杂交幼苗在完全营养液中生长7天，然后评估不同时期缺磷下硝酸盐吸收的动力学。硝态氮的吸收减少60%后，短期的磷饥饿（2天），停止时，磷被扣留超过6天。氮素吸收在磷恢复后恢复，但恢复所需的时间和程度取决于磷饥饿的时间。
Single cross seedlings of the male progenitor of the double cross hybrid, BR 201, were grown for seven days in a complete nutrient solution prior to evaluating the kinetics of nitrate uptake under varying periods of phosphorus deficiency. Nitrate uptake decreased 60% after a short period of phosphorus starvation (2 days) and ceased when phosphorus was withheld longer than six days. Nitrate uptake resumed after phosphorus (P) was re-supplied, but the time required and extent of recovery depended on the length of phosphorus starvation.
