一、植物抗寒防寒研究对果树阻抗变化的抗寒作用有关资料的评价在结冰和化冰期间记载不同栽培品种的苹果枝梢的电阻和温度,用装置四个电极的转换器在1000赫兹测定其阻抗,在结冰期间阻抗性状的变化保持恒定,曲线的位移表示细胞结构的差异.细胞结构的差异取决于温度和滞后作用的大小,结冰时的滞后作用大于化冰时的滞后作用,这种差异包含着滞后作用的大小,滞后作用的范围随着组织对寒害感受性的提高而增大.
First, the plant cold hardiness cold research on resistance to changes in the fruit of the cold effect of the evaluation of the relevant information in the icing and icing during the recording of different varieties of apple shoot tip resistance and temperature, with the device four electrode converter at 1000 Hz The impedance changes during the icing are kept constant, and the displacement of the curve indicates the difference of the cell structure.The difference of the cell structure depends on the temperature and the effect of the hysteresis, the hysteresis in the icing is greater than the hysteresis in the icing , This difference contains the size of the lag effect, the scope of the lag effect increases as the organization increases the susceptibility to cold damage.
