| 摘 要： | 试验结果表明，外源Ｈ２Ｏ２浓度低于０．４％时，对小麦种子萌发有促进作用；Ｈ２Ｏ２浓度超过０．４％时，则抑制种子萌发，其抑制程度随着Ｈ２Ｏ２浓度的增大而加强；Ｈ２Ｏ２对主胚根和胚芽的伸长均有抑制作用，并且对主胚根的抑制强于胚芽；低浓度（小于０．４％）Ｈ２Ｏ２能够促使侧生胚根的伸长，增加胚根数；叶片中ＰＯＤ活性和ＭＤＡ含量与Ｈ２Ｏ２浓度均存在密切的相关性。

| Abstract: | The experiment showed: Low concentration of H2O2(<0.4%)promoted Wheatseed sprouting. However, the higher concentration of H2O2(>0.4%),the greater in-hebiting effect on the growth of principal embryonic root and embryonic bud,and the ef-feet on the former was more intense than on the later .Low comcentration of H2O2(<0.4%)could make the number of embryonic root increase. Leaf POD activity and MDAcontent existed positive correlations with H2O2 concentration. |
