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
