Abstract: With the Viburnum awabuki that have grown three years as experimental materials , the paper measured and compared the difference among leaves which was disposed under various low temperatures including the activity of Protective enzyme and the contents of water-soluble sugar and water-soluble protein .The results that with the extend of processing time, the activity of SOD、POD and CAT increased at first then decreased and so it was with the contents of water-soluble sugar and water-soluble protein showed the existence and enhancement of protective enzymes lightened the damage,which aroused by membrane lipid peroxidation;it may be an important reason why Viburnum awabuki enhance their chilling resistance and escape low temperature damage.
