摘要
该试验研究了5个抗寒性不同的梨品种休眠期间枝条水分状况、细胞膜透性以及束缚水/自由水比值与抗寒性之间的关系。结果表明,抗寒性强的梨品种,束缚水/自由水比值在1.0以上;抗寒性弱的梨品种,束缚水/自由水比值在1.0以下。
In this experiment,changes in water stadus,cell membrane permeability,the relationship between bound water/free water ratio and hardiness in five pear cultivars with different cold hardiness under dormancy period were studied.The results showed that the bound water/free water ratio in some hardier cultivars was beyond 1.0,whereas that in the less hardy cultivars was below 1.0.
