| 摘 要： | 目的]探讨5种地被植物在南京地区冬季抗寒生理变化机制。方法]以5种地被植物叶片为实验材料,测定低温处理过程中其相对电导率、MDA含量、SOD和POD活性等,分析低温下不同地被植物的抗寒能力。结果]5种地被植物相对电导率随处理温度降低而上升,但相对电导率大小差异明显,常绿油麻藤在低温处理过程中一直维持较低水平,其MDA含量变化幅度均较小,含量水平为最高。随温度下降花叶蔓长春、鸡血藤和扶芳藤SOD活性先上升后下降,常绿油麻藤SOD活性一直上升。综合评价各地被植物其抗寒能力大小依次为:常绿油麻藤>鸡血藤>常春藤>扶芳藤>花叶蔓长春。结论]5种地被植物的抗寒性具有明显差异。

| Abstract: | Objective] The aim was to discuss the cold resistance physiological change mechanism of 5 cover plants in winter in Nanjing area.Method] With the leaves of 5 cover plants as the tested material,the relative conductivity,MDA content,SOD activity and POD activity were determined during the cold treatment to analyze the cold resistance ability of the different cover plants under the low temperature.Result] The relative conductivity of 5 cover plants were increased with the decrease of treatment temperature,... |
