Abstract

Nodule nitrogen fixation activities were higher in pod-setting stage whereas nodule and middle-upper stem ureide contents were higher in late pod-filling stage. Ureide concents in nodules and middle-upper stems of eight wild soybean lines with different seed protein contents were significantly positively correlated with nodule nitrogen fixation activities Significantly positive correlations between nodule nitrogen fixation activities, middle-upper stem ureide contents and seed protein contents were observed. Middleupper stem ureide contents may be used as an index of nitrogen fixation capacity in wild soybean lines.
