摘　　要：为了解引种树种在佛山的适应性,对佛山植物园于2010年5月引种的大叶桃花心木等16个树种的生长表现进行调查和分析。结果表明:引种栽培的16个树种中,千果榄仁存活率最高,为93.75%,对当地的立地条件适应性较好;绒毛番龙眼存活率最低,为50.00%,其次是焕镛木,存活率为55.00%,这2种树木对当地立地条件适应性较差,须加强养护管理。在聚类分析中,千果榄仁、亮叶木莲、大叶桃花心木、绒毛番龙眼属于第3类,平均隶属函数值分别为1.00、0.77、0.72和0.70,其生长量较大,生长速度较快;而百日青、菲岛福木在聚类分析中属第1类,平均隶属函数值分别为0.04、0.06,生长量较低,生长速度较慢。In order to understand the adaptability of the introduced tree species in Foshan,the growth performance of the sixteen tree species including Swietenia macrophylla,etc.which were introduced by Foshan Botanical Garden in May 2010 was investigated and analyzed.The results showed that among the sixteen tree species introduced and cultivated,the survival rate of the Terminalia myriocarpa was the highest,reaching 93.75%,with good adaptability to local site conditions;while the survival rate of the Pometia tomentosa was the lowest,reaching 50.00%,followed by Woonyoungia septentrionalis with a survival rate of 55.00%,which had poor adaptability to local site conditions and required strengthening management.In cluster analysis,Terminalia myriocarpa,Manglietia lucida,Swietenia macrophylla,and Pometia tomentosa belong to the third category with an average membership functions of 1.00,0.77,0.72,and 0.70,respectively.Their growth amounts are large and the growth rate sare fast.On the contrary,in the cluster analysis,Podocarpus neriifolius and Garcinia subelliptica belong to the first category withthe average membership function values of 0.04 and 0.06,respectively.They have lower growth amounts and slower growth rates.
