摘要
采用以生物膜学说为依据的电导法,对延边地区常见梨品种的花芽及枝条组织进行了抗寒性测定.结果表明,不同梨品种的相对电导率和伤害率与温度呈线性相关,相关系数均达极显著水平。
The cold resistance of common pear cultivars' buds and shoots were determined with electric conductance method based on the biologic membrane theory. The results showed that the relative electric conductance and injury ratio represented linearity correlation to temperature and the coefficients of correlation reached highly significant level.
