摘要: 玉米黄化幼苗经4~5℃低温处理36小时后,膜脂组成在自交系间、处理和对照间没有差异;膜脂肪酸不饱和度发生明显变化,抗性强的自交系不饱和指数提高,抗性差的不饱和指数降低,膜结合酶(叶绿体K+-Mg2+ATPase和线粒体Na+-K+ATPase)活性降低,抗性差的自交系膜结合酶活性降低幅度大于抗性强的自交系。

Abstract: After the yellowish seedlings of maize inbreds treated at 4 0C and for 36 hours, the IUFA (Index of Unsaturated Fatty Acids) of cold-resistant inbreds increased where the IUFA of cold-sensitive inbreds decreased, The IUFA of the latter was higher than that of the former no matter whether the temperature was normal or low, Activities of both mitochondria membrane linked K+-Na+ ATPase and of chloroplast membrane linked K+-Mg十十ATPase decreased at low temperature, and the ATPase activity of the cold-sensitive inbreds decreased more severely than that of the cold-resistant inbred.

Key words: Maize, Cold resistance, Membrane lipidf, ATPase
