| 摘 要： | 以青藏高原高寒草甸自然生长条件下的矮嵩草(Kobresia humilis(C.A.Mey ex Trauvt)Serg.)为对象,研究绿色植物生长调节剂(GGR)对其生理过程的影响。结果表明:抗氧化酶超氧化物歧化酶(SOD)活性在6月份和8月份显著高于对照样地的活性(P<0.05),在7月差异不显著;抗氧化剂谷胱甘肽(GSH)含量差异不显著;处理样地可溶糖性含量随时间呈倒"S"形变化,而对照样地的含量呈"V"字形变化,处理样地显著高于对照样地(P<0.05);在7月和8月可溶蛋白含量显著高于对照(P<0.05);施用GGR提高了矮嵩草叶片的叶绿素a、b和总叶绿素含量;在生长初期和后期,显著降低了矮嵩草叶片超氧阴离子自由基(O2-)的产生速率。施用GGR提高了矮嵩草叶的抗氧化能力和渗透调节能力,促进植物的生长。

| Abstract: | In order to provide scientific basis for the use of GGR on the plant growth,the physiology response perennial grass Kobresia humilis(C.A.Mey ex Trauvt.) Serg was studied outdoors in Qinghai-Tibet Plateau in 2006 by spraying GGR on the alpine meadow.The results show that the activity of superoxide dismutase(SOD) was significantly higher than that in control in June and August(P<0.05),but not significant in July.The content of glutathione(GSH) was not significantly influenced.The change of soluble sugar conte... |
