Abstract: Study the relationships between the shoot or root acid phosphatase activity ( APA) and phosphorus utilization ratio under different phosphorus treatments, to provide a basis for screening P efficiency varieties in soybean.Under three different P supply levels, the soybean shoot and root acid phosphatase activities and P utilization ratio of 12 genotypes were determinated and contrasted. The root acid phosphatase activities of 159 genotypes were also detected under 2 μmol /L P concentration. The results showed that soybean root acid phosphatase activity was positively correlated with P utilization ratio significantly ( r > r0. 01) under 2 μmol /L P concentration. Six phosphorus efficiency varieties were screened out from 171 experimental genotypes. Under low phosphorus concentration, soybean root acid phosphatase activity coule be used as an important biochemistry index to screen P efficient genotype.

Key words: Soybean, Acid phosphatase activity( APA) , P utilization ratio, P efficient varieties
