Abstract Taking soybean variety Heinong No.38' (Glycine max (L.) Merrill cv. Heinong No.38) grown in pots as the test material,this paper studied the changes of ureide (allantoin and allantic acid) contents in leaves,acetylene reduction activity of soybean root nodule and activity of allantoate amidohydrolase during day-to-day soil drought after adding MnSO4 to soybean root in pots. The result showed that leaf ureide content increased and the nitrogenase activity of soybean root nodule decreased by feedback inhibition under drought. MnSO4 added to soybean root in pots increased allantoate amidohydrolase in leaves,decreased leaf ureide content during drought,and enhanced N2 fixation. It was suggested that Manganese applied to soybean could promote leaf ureide breakdown,lessen feedback inhibition of nodule activity,and prolong the tolerance of N2 fixation by soybean to drought.
