以现代海棠中的凯尔斯海棠、雪球海棠和钻石海棠5年生苗阳面当年生功能叶片为试验材料，研究低温胁迫（-4℃、-8℃、-12℃、-16℃、-20℃、-24℃、-28℃、-32℃）与4℃冷藏（ CK ）条件下的游离脯氨酸、丙二醛含量和相对电导率等生理指标的变化规律。结果表明，随着温度的降低，离体叶片的脯氨酸含量、丙二醛含量和相对电导率都呈不同程度的增加趋势；对各项测定指标及变化幅度进行比较及分析，3种现代海棠的抗寒力排序为雪球海棠＞凯尔斯海棠＞钻石海棠。

The variation of Proline ( Pro ) , malondialdehyde ( MDA ) and relative electric conductivity at low temperature stress (-4℃, -8℃, -12℃, -16℃, -20℃, -24℃, -28℃, -32℃) and 4℃ ( CK ) were studied by using functional annual leaves from 5-year-old seedlings of modern crabapples , namely Malus‘kelsy’, M.‘Snowdrift’ and M.‘Sparker’.The result showed that the content of Pro.MDA and relative e-lectric conductivity presented an upward trend with the decrease of temperature.The cold-resistance capacity of these 3 modern crabapple was in the order of M.‘Snowdrift’ >M.‘kelsy’ >M.‘Sparker’.
