摘　　要：棕榈科(Palmae)植物是热带地区重要的代表植物。实践证明,低温伤害是棕榈科植物北移的重要限制因子。研究以南昌市园林中栽培应用的6种棕榈科植物:蒲葵(Livistona chinensis)、华盛顿棕(Washingtonia robusta)、加拿利海枣(Phoenix canariensis)、银海枣(Phoenix sylvestris)、布迪椰子(Butia capitata)、美丽针葵(Phoenix roebelnii)为材料,研究其在低温胁迫下相对电导率、过氧化物酶(POD)、丙二醛(MDA)等生理生化指标变化,并配合Logistic方程求其半致死温度,以期了解它们的抗寒能力,为"南棕北移"尤其是棕榈科植物在长江流域的应用提供参考。Palmae plants are important representative tropical plants .Practice shows that chilling injury is an important limiting factor for northward movement of palme trees .Six palmae plants：Livistona chinensis , Washingtonia robusta,Phoenix canariensis,Phoenix sylvestris,Butia capitata,Phoenix roebelnii cultivated in the gardens in Nanchang City were used as materials ,the effect of low temperature stress on physiological and biochemical indicators such as relative conductivity ,MDA content,POD activity,and semilethal temperature with logistic equation were studied to understand their cold resistance ,so as to provide reference for the north-ward movement of south palme trees ,especially the application of palme plants in the Yangtze river basin .

关 键 词：棕榈科植物 低温胁迫 抗寒性 相对电导率 MDA含量 POD活性
