Study on Analysis of Drought Resistance in Soybean

Study of drought resistance was made in ten soybean varieties of physiological types.Five kinds of physiological indexes releated to drought resistance in seedling stage and flowering poding stage were studied in both normal and drought conditions. Analysis of variance for field experiment was also made.The result were as follows: the corelation coefficients between the average of subordinate function value of five physiological indexes-relative water content(RWC),relative conductivit,net photosynthesis velocity , the peroxidase(POD) and free prolin content and drought resistance coefficient were not significant(r=0.2104) in seedling age;the weighed average of subordinate function values of five physiological indexes and drought resistance coefficient were positively significant(r=0.8745~(**),p0.01).
