摘　　要：本文采用实地调查、对比与分析等方法研究了新引种棕榈类植物在上海地区的低温适应性。以近年来在上海园林中广泛应用的沙巴棕榈、华盛顿棕榈、布迪椰子、银海枣以及加拿列海枣作为对象,调查研究了这些树种在上海园林绿地中的冬季适应情况及越冬保护情况。通过寒害指数来衡量其受害程度的结果表明,新引种的棕榈类植物都有不同程度的寒害或冻害现象发生,需要依靠一定的保护措施安全越冬。Sabah palm, Washingtonia filifera H.Wendl., Butia capitata Becc., Phoenix sylvestris Roxb. and Phoenix canariensis Hort. ex Chabaud SF. which were applied widely in Shanghai open greening spaces, were selected as objects in this paper. The growth status and the adaptability and the protection in low-temperature season of these palm species were investigated. The result showed that all of these species were injured in freezing days; some plants were even died by synthetic chilling damage index. These plants survived by some protections during low-temperature season.
