Relativity Analysis between Acid Phosphatase Activity and Screening Genotypic Variation in P Efficiency of Soybean
摘要
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 soy -bean.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 ,soy-bean root acid phosphatase activity coule be used as an important biochemistry index to screen P efficient genotype .关键词
