通过对茶树受冻害情况调查和茶树叶片含水量测定 ,分析了茶树受冻害程度与茶树叶片单叶重、总含水量、自由水含量、束缚水含量及束缚水与自由水的比值的相关性 ,结果表明 :茶树叶片总含水量、自由水含量、束缚水含量分别为 0 5 2g/g~ 0 63g/g、0 2 5g/g~ 0 43g/g、0 15g/g~ 0 3 3g/g ;茶树受冻害程度与束缚水含量、束缚水与自由水的比值、叶片单重存在负相关性 ,与总含水量、自由水含量存在正相关性 Based on the investigation of the frost damage and the determination of the leaf water content of the tea tree, the correlation between the frost damage degree of tea tree and the leaf single leaf weight, the total water content, the free water content, the irreducible water content and the ratio of irreducible water to free water were analyzed. The results showed that the total leaf water content, free water content and irreducible water content were 0 5 2 g / g ~ 0 63 g / g, 0 2 5 g / g ~ 0 43 g / g, 0 15 g / g ~ 0 3 3 g / g The degree of frost damage and bound water content, the ratio of irreducible water to free water and the single leaf weight of tea plants were negatively correlated with the total water content and free water content
