| 摘 要： | 使用不同浓度的CaCl2处理垂枝樱花(Cerasus subhirtella var.pendula)插穗来研究氯化钙处理对插穗生根、抗氧化酶活性以及过氧化产物丙二醛(MDA)含量的影响。结果表明:55 mg/L CaCl2处理垂直樱花,其插穗的生根率可达40%,而对照仅有22%。处理的插穗在单株生根数量、根系活力与根鲜样质量方面,均显著优于对照,而且插穗叶片中超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)和抗坏血酸过氧化物酶(APX)等保护酶的活性也显著增强,MDA的含量则显著降低。

| Abstract: | The effects of CaCl2 on antioxidant enzyme activities,rooting,malondialdehyde(MDA) content in cutting leaves of Cerasus subhirtella var.pendula were studied.The results showed that the rooting rate could be up to 40% by using 55 mg/L CaCl2,for the control was 22%.The single plant rooting number,root activities,root fresh mass were significantly better than the control,and the enzyme activity of super superoxide dismutase(SOD),peroxidase(POD),catalase(CAT) and ascorbic acid peroxidase(APX) were enhanced sign... |
