Abstract: Xiamen area was suffered a strong cold wave in January 22－27, 2016, causing cold damage on Zingiberales plants in Xiamen Botanical Garden. The temperature reached the lowest point at –2 ℃ in January 24. The damage degrees of the plants were divided into 6 levels. 38 species of Zingiberales plants were investigated. Only 4 species were not hurt in 38 species after the cold wave. Zingiberaceae and Strelitziaceae had higher resistance to cold wave, while Heliconiaceae and Costaceae were more damaged in the cold-air outbreak. The cold resistance of Alpinia was better than that of Heliconia and Costus. Results showed that the latitude of habitat was the major factor affecting the cold resistance of Zingiberales plants. Species from lower latitude were more damaged when suffered the cold wave. The elevation of habitat also affected the cold resistance of Zingiberales plants.

Key words: Zingiberales plant, cold wave, habitat, latitude

摘要： 2016年1月22～27日厦门地区出现近二十多年来未遇的极端低温天气，厦门植物园的姜目植物受到不同程度的危害。将姜目植物受害程度划分为6个受害等级，调查园内38种姜目植物的受害情况。结果表明，38种姜目植物中有34种受不同等级冻害，未受害仅4种；姜科和旅人蕉科表现较为耐寒，蝎尾蕉科和闭鞘姜科抗寒性差；山姜属抗寒能力强，蝎尾蕉属、闭鞘姜属抗寒能力弱。研究表明，原产地纬度与姜目植物抗寒能力显著相关，原产于低纬度的姜目植物易受低温危害；原产地海拔也影响姜目植物抗寒能力。
