| 摘 要： | 以硝普钠作为NO供体，研究外源NO对芽涝玉米的影响。结果表明，外源NO能延缓芽涝玉米根系活力下降和质膜相对透性增加，抑制叶绿素降解，维持叶片光合能力；外源NO能提高芽涝玉米根系SOD、POD、CAT等抗氧化酶的活性，可以提高玉米对芽涝的抵抗能力。

| Abstract: | Using sodium nitroprusside(SNP) as a donor of exogenous NO, the effects of exogenous NO on maize seedlings under water logging stress were studied. The results indicated that exogenous NO could retard the decrease of root activity and the increase of relative plasmalemma permeability of maize seedlings under water logging stress. Exogenous NO could restrain the decomposing of chlorophyll, maintain the photosynthetic capacity of maize seedlings under water logging. Exogenous NO could increase the activity of antioxidant enzyme such as SOD, POD, CAT. Exogenous NO could increase the ability of anti-water logging stress of maize seedlings. |
