Abstract
Numerous researches have been done on the response of crops to low phosphorus (P) deficiency, but few is involved in the yield structure of the research materials, which is very crucial for crop P efficiency breeding. The present study analyzed the response to P deficiency of two winter wheat cultivars with different yield components, ND3291(numerous ears) and J9428(few ears). When P deficiency was not serious(olsen-P 6.6 mg/kg, P applied 30 kg/hm 2), the yield of ND 3291 was reduced significantly, which was due to the decrease of ear number .Under this condition, yield and yield components of J9428 were not reduced significantly. When P deficiency was serious(olsen-P 2.4 mg/kg, No P), the effect of P deficiency on two cultivars was identical. Yield and yield components of the two cultivars were all reduced. Among three yield components, ear grain number was reduced greatest. It is because that the low P nutrition level of plant leaded to the decreasing of the number of spikelets and florets per ear. The results also showed P deficiency didn't affect the starch accumulation in grains, so P deficiency had less impaction on thousand-grain weight than other yield components.
