The N use efficiency of four tissues and whole plants of two cultivars (IIY084 and WYJ23) subjected to ambient (A) and elevated [CO2] (F) at none (0N) and normal N levels (NN) at three stages (different letters in each column indicated significant differences in each tissue among eight treatments at each sampling date according to LSD at 5% level. -; one-way ANOVA was not applied since no significant interactions of [CO2], cultivar, and N were observed)
