| 摘 要： | 试验探讨了低温处理后,植物生长调节剂对香樟叶片细胞膜透性和保护酶活性等生理代谢的影响,以期客观地评价香樟的抗寒力和引种到暖温带地区应用的可行性,为北方地区引种栽培提供理论依据。结果表明,低温处理后,香樟叶片的细胞膜透性和保护酶活性均有不同程度的变化,当植物生长调节剂喷施的质量浓度达到300 mg/L时,香樟叶片的SOD、POD、CAT活性明显提高,相对电导率、Pro和MDA含量相对下降。

| Abstract: | The effects of plant growth regulators on the leaf membrane permeability and protective enzyme activity in cold treated Cinnamomum camphora(L.) Presl were discussed to provide a theoretical basis for the feasibility of introduction of this plant into northern area.The results showed that the physiological indicators including SOD,POD,CAT,electrolyte leakage rate,Pro,MDA were influenced in some degree when different concentration of plant growth regulators was sprayed on the leaves.SOD,POD and CAT activity was the highest and the relative conductivity,Pro and MDA content was the lowest when the concentration of plant growth regulator was 300 mg/L. |
