| Abstract: | Under three levels P stress treatment,shoot and root acid phosphatase activities,crown-root ratio,amount of dry matter,phosphate content,and P efficiency of 23 soybean cultivars were studied by determination,comparison and analysis.The result showed that there was significant variance among shoot or root acid phosphatase activities,relative value of shoot and root acid phosphatase activities,crown-root ratio,P efficiency,and relative value of P efficiency(P
