Abstract：In order to examine the effects of Wx genes on SOD activity of wheat leaves at grain filling stage,the SOD activities of flag leaf and top second leaf were measured in eight Wx near-isogenic wheat lines. The results showed that the absence of Wx-D1 gene could increase the SOD activity of leaves,but the absence of Wx-A1 and Wx-B1 genes had no significant effect. Although all Wx genes were absent,the SOD activity of WxABD was relatively higher,so there might be some interaction among the Wx genes. The SOD activity of flag leaf was lower than that of top second leaf in the same period,and it might decrease in the environmental stress.
