摘　　要：以3年生珊瑚树为实验材料,进行植物耐寒性研究,采用人工冷冻处理,对不同处理温度叶片的保护酶活性、可溶性糖含量、可溶性蛋白质含量等指标进行测定分析。结果表明:随着低温处理时间的延长,珊瑚树叶片SOD、POD、CAT活性、可溶性糖、可溶性蛋白质含量均呈先升高后下降的趋势;说明叶片内保护酶的存在和活性的提高减轻了由膜脂过氧化引起的伤害,是珊瑚树提高抗寒性、避免低温伤害的重要原因。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, whi peroxidation; it may be an important reason why Viburnum awabuki enhanc escape low temperature damage.
