为研究Wx基因对小麦叶片SOD活性的影响,对8个Wx近等基因系灌浆期旗叶和倒2叶SOD活性进行了测定和分析。结果表明： Wx-D1基因的缺失可提高植株SOD活性,而Wx-A1和Wx-B1基因的缺失则无显著影响；WxABD丧失了所有Wx基因,但其SOD活性却相对更高,可能是几个Wx基因之间存在互作关系；旗叶SOD活性低于同时期倒2叶,SOD活性在不利环境中可能降低。

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.
