| 摘 要： | In order to reveal the cold resistant mechanism of tea plant,two varieties with different cold resistances were studied.The activities of catalase （CAT）,peroxidase （POD）,superoxide dismutase （SOD） and polyphenol oxidase （PPO） were investigated,and the contents of soluble protein,sugar and malondialdehyde （MDA） were determined in fresh tea leaves in the autumn.The results showed that the activities of POD and the content of soluble sugar were both much higher in the variety with strong cold resistance,and the content of soluble protein was associated with the cold resistance,while the cold resistance of the plant was not related with the activities of the CAT,SOD and PPO,and the content of MDA.It is considered that the activity of POD and contents of soluble sugar could be used as indicators to identify the cold resistance of tea varieties.
