In order to analyze and evaluate the indexes of soybean tolerane to low phodphalt,and screen the important targets closely related to soybean tolerance to low phosphorus,this paper selected 41 soybean cultivars,and compared and analyzed their coefficient of low phosphorus tolerance,and carried out clustering analysis by NTSYS software on acid phosphatase activity of root tip with relavant plant high,amount of dry matter with low-P tolerance coefficient of phosphrous utilization rate. The results under the t...
