Abstract: The transition temperature at wich activation energy(Ea)changed for cytochrome oxidase was closely correlation with chilling-resistant level of maize varieties.This indicated that the transition temperature of Ea changed for the enzyme was a better biochemical index wich reflected maize resistant ability to chilling injury.Their statistical data can be used to differentiate chilling-resistant level of maize in shoot period.The index of unsaturation fatty acid and palmitoleic acid/linoleic acid in mitochondrial membrane lipids can be used as biochemical index of chilling-resistance in some plants.The molecular percent of unsaturation fatty acids in the membrane lipids was not sure whether it can be used as biochemical index of chilling-resistance.The potenciality of chilling-resistance in maize in shoot period was very small.

Key words: Chilling-resistant level, Maize, Cytochromc oxidase, Transition temperature of activation energy, Mitochondrial membrane lipids
