| The difference of phosphorus nutrition characteristics of 33 soybeans varieties were studied with pot experiment and with two phosphorus fertilizer(P2O5) rate treatments of P0(0 mg/kg) and P1(0.15 mg/kg) to provide evidence for exploration and utilization of soybeans phosphorus efficiency germplasm.The results showed that in P deficient condition,the tested soybean varieties were classified to three classes by dendrogram by those nutrition traits,among which class1(with highest seed yield and P accumulation quantity,and with medium P utilization efficiency) showed best complex phosphorus nutrient trait;in P abundant condition,the tested soybeans varieties were classified to four classes,among which class 1(with highest seed yield and P accumulation quantity,and with higher P utilization efficiency) showed best complex phosphorus nutrient trait.Statistical analysis showed that the correlation between the plant P accumulation in seedling and harvesting reached over significant level (P0,r=0.5096**;P1,r=0.3596*);in seedling,the plant P accumulation had significant correlation with plant dry weight(P0,r=0.8124**;P1,r=0.8724**) and dominated the plant growth;in harvesting,the effect of P utilization on seed soybean yield increased;but which still was less than that of P accumulation. |
