- Abstract:
- ?In order to clarify the root physiological characteristics of superhighyielding soybean,root activity and nodulation characteristics were determined through potted experiments with super-high-yielding soybeancv.Liaodou 14 and Zhonghuang 35,and common soybean cv.Liaodou 11 as materials.Root bleeding sap weight and root activity of super-high-yielding soybeans were much greater than those of common soybean at R4 and R6 stage,and root bleeding sap weight showed statistically significant differences at R2 stage between super-high-yielding and common soybean,while root activity of Liaodou 11 was maximum at R2 stage.Root bleeding sap weight and root activity were much higher than other fertilizer treatments under 100 mg·kg-1(NH4)2PO4treatment at R2 and R4 stage.Nodule weight,nitrogenase activity and amount of nitrogen fixation of super-high-yielding soybeans were also much greater than those of common soybean at R4 and R6 stage.Results suggest super-high-yielding soybeans had stronger root physiological activity at middle to late seedfilling stage.
