摘要
通过对彩色马蹄莲不同低温的胁迫处理,进行叶片保护酶活性、MDA含量和叶绿素含量及叶片质膜透性等抗性指标进行测定分析。结果表明:随着处理温度的降低,叶片的相对电导率值、MDA含量和Pro酶活性显著升高;叶片SOD酶活性和叶绿素含量表现为随着温度的降低而逐渐降低的变化趋势。低温下耐寒性强的品种能保持较高的SOD和Pro酶活性和较低的MDA含量。
This paper analyzed the resistance index of leaves by giving the low temperature to Zantedeschia hybrida at different level.The results showed that by the reducing of temperature,the relative conductivity,MDA content and Pro enzyme's competence marked increase,but SOD content's activity and the content of chlorophyll depress.The frost resisting breeds could keep high level of SOD and Pro enzyme's competence,and at low MDA content.
