摘要
以厦门植物园引种的5 6种棕榈科植物为材料,应用相关分析、通径分析、决定系数分析等方法,分析原产地的经纬度、海拔、植物的生态学特性、定植时间等因素对引种结果的影响。结果表明:影响厦门地区引种棕榈植物的3个关键成败因子是原产地的纬度、海拔和引种定植时间;分布于南北纬2 0°以上的中纬度棕榈植物、分布于高海拔的种较易获得引种成功;引种定植时间宜于初春之后到秋季之前进行;棕榈植物原产地的经度以及内陆或沿海适应性,对引种棕榈植物影响较小。
More than 400 species of palms have been introduced and cultivated in Xiamen Botanical Garden during the past 43 years.The factors affecting palms introduction were studied in the paper,according to longitude,latitude,elevation,organism habits,suitability and planting time of 56 species,by the methods of correlation analysis,path analysis and determination coefficient analysis.The results showed that;1)Latitude,elevation and planting time were 3 key ecological factors affecting introduction of palms in Xiamen.2)The palm plants distributed between 20～44° north and south latitude,and seeds introduced from area with high elevation were easy to obtain success.3)It was good time from March to September to plant the introduced palms.4)The longitude of original habitat and the suitability to coastal or interior were the factors less affecting the result of introduction of the ornamental_palm plants in Xiamen.
