| 摘 要： | 以中棉所１８为材料，研究了大田条件下ＤＰＣ（缩节安）系统化控对棉叶发育和活性氧代谢的影响，结果表明，ＤＰＣ提高了叶片中叶绿素、可溶性蛋白的含量，降低和减轻了膜脂过氧化产物丙二醛（ＭＤＡ）的积累，提高了超氧物歧化酶（ＳＯＤ）活性，降低了过氧化氢酶（ＣＡＴ）、过氧化物酶（ＰＯＤ）活性，改善了活性氧代谢。ＤＰＣ具有显著延缓叶片衰老的效应，可能与改变了内源激素系统、改善了活性氧代谢有关。 |

| Abstract: | Effects of DPC(N,N-dimethyl piperidinium chloride)on physiological changesduring development of leaves were studied under field condition using Gossypium hirsutumL. cv. CCRI 18 as material,indicating that all the contents of Chlorophyll a,a+b andwater soluble protein were increased apparently,and activity of SOD were stimulatedwhile those of CAT,POD were inhibited and the action oxygen metablism were ameliorat-ed(the)MDA content in leaf were decreased).The senescence of leaf were delayed and thechanges mentioned above may be resulted from the regulation of DPC on leaf endogenioushormons. |
