| 摘 要： | 为了探索Ca2＋对植物抗寒性的影响,了解植物抗寒机理,在低温胁迫前用不同浓度CaCl2溶液浇灌北海道黄杨扦插植株,然后对植株进行4℃低温胁迫。研究不同浓度CaCl2对4℃低温胁迫过程中叶片渗透调节物质,抗氧化酶（SOD、POD和CAT）活性以及丙二醛含量的影响。结果表明,用10mmol/L CaCl2处理北海道黄杨植株,能显著提高低温胁迫过程中叶片脯氨酸和可溶性蛋白含量,改变抗氧化酶活性,降低MDA含量。

| Abstract: | For investigating the effects of calcium chloride on cold resistance and the mechanism of the plant's cold resistance,cuttings of Euonymus japonicus cv.'Cuzhi' were irrigated by calcium chloride with different concentrations before cold stress.Then they were transferred at 4 ℃.The osmo-regulatory substances,activity of antioxidant enzymes(SOD,POD,CAT) and MDA content of leaves at 4 ℃were observed.The results showed that 10 mmol/L of calcium chloride could significantly increase the content of the proline and soluble protein,change the activity of antioxidant enzymes,and decrease the content of MDA during cold stress. |
