一、茶树冻害的生物学机理水是任何生物的载体,动植物体内大约70%的重量都是水,对于茶树而言也不例外。茶树之所以受到冻害,主要原因是与茶树体内的水份有很大的关系,茶树受冻都是由于低温引起的细胞中水份结冰。当温度降到零度下时,茶树细胞液开始结冰,此时如果继续降温,细胞自由水也随着结冰,细胞收缩,细胞水
First, the biological mechanism of tea tree frost Water is a carrier of any biological plants and animals about 70% of the weight of water, for tea is no exception. The reason why the tea tree is frostbite is mainly due to the great relationship with the water inside the tea tree. The freezing of the tea tree is due to the freezing of the water in the cell caused by the low temperature. When the temperature dropped to zero degrees, the tea cell liquid began to freeze, then continue to cool down at this time, the cell free water also with icing, cell contraction, cell water
