摘　　要：以金叶莸、榆叶梅1年生离体枝条为试验材料,经过6个不同低温的处理,用电导法测定其相对电导率,并测定低温下植物丙二醛含量、脯氨酸含量的变化。研究结果表明,低温对膜稳定性有影响,这2种植物的抗寒性具有明显差异。榆叶梅的抗性较强,而金叶莸较差。Taking annual isolated branch of Caryopteris clandonensis‘Worcester Gold’and Amygdalus triloba as the experimental materials, the values of their relative conductivity under six different low temperatures treatments were determined. The influences of low temperature on the malondialdehyde content and proline content indicated that low temperature can affect the stability of cell membrane. There are some obvious differences between the two kinds of plant’s cold resistances. The cold resistance of Caryopteris clandonensis ‘Worcester Gold’is stronger than that of Amygdalus triloba.
