冻害严重影响冬油菜的生长。为揭示冬油菜抗寒机理，采用植物动力2003喷施杂1613与湘油15号油菜，以喷施清水为对照进行比较。生理指标测定结果：喷施植物动力2003的油菜叶片电导率、丙二醛含量比对照低，SOD活性、SPAD值、可溶性蛋白、可溶性糖及脯氨酸含量比对照高；2品种间的可溶性蛋白含量、SOD活性差异不大。由此表明，植物动力2003可提高油菜抗寒能力。

Cold injury seriously affects the growth of winter rapeseed. In order to reveal the cold resistance mechanism of winter rapeseed,effect of Plant Power 2003 (PP2003)on Za 1 61 3 and Xiangyou No. 1 5 was studied with water treatment as control. The results showed that spraying PP2003 could reduce the conductivity and content of malondialdehyde in win-ter rapeseed leaves,while the activity of SOD,SPAD value,content of soluble protein,content of soluble sugar and proline were heightened. There had little difference in SOD activity and soluble protein content between Za 1 61 3 and Xiangyou No. 1 5....
