| 摘 要： | 目的]研究彩色马蹄莲抗寒性形成的生理生化机制。方法]通过测定彩色马蹄莲叶片可溶性糖含量、丙二醛含量、游离脯氨酸含量和叶绿素含量，研究3个彩色马蹄莲品种（M1、M5、M8）在自然条件和人控低温（光照14h，平均温度5℃）条件下这些生理指标连续7d的变化规律。结果]从连续7d的变化情况看，3含彩色马蹄莲品种叶片可溶性糖含量、丙二醛含量、游离脯氨酸含量均较对照有所上升；叶绿素含量随着低温胁迫时间的延长逐渐下降。结论]3个彩色马蹄莲品种都对低温胁迫产生了积极的响应，所受的低温伤害有所减轻，总体表现为M1最好，M5次之，M8最差。

| Abstract: | Objective]The research aimed to study the physiological and biochemical mechanism of cold resistance formation of colored common callalily.Method]By measuring physiological indices of the content of soluble sugar,malondialdehyde and free praline,3 kinds of colored common callalily(M1、M5、M8) leaves under controlled cold condition(day length 14 h,mean temperature 5 ℃)and natural conditions were researched.Result]The results showed that,the content of soluble sugar,MDA and free proline of 3 kinds cultivars leaves under controlled cold conditions increased.The content of chlorophyll of tested materials decreased with the degree of cold stress.Conclusion]3 Zantedeschia cultivars showed optimistic response to cold stress and their cold tolerance increased.In 3 tested Zantedeschia cultivars,M1 adapted to cold conditions best,followed by M5,and the last one was M8. |
