摘　　要：从2004年至2009年在昆明市呈贡县进行了绒叶含笑、马关木莲、状丽含笑、香木莲、小果含笑、大果木莲、金花含笑、单性木兰8种木兰科树种的苗期适应性研究。5年多的育苗试验结果表明:单性木兰、金花含笑、大果木莲为该地区不适宜育苗用的木兰科树种。现存的5个木兰科树种苗木的保存率顺序是:绒叶含笑>香木莲>状丽含笑>马关木莲>小果含笑。适应性差或抗寒力弱的单性木兰等3个树种的苗木已在逐年的霜冻中被冻死。现存树种是苗期抗寒力较强的树种,其苗木的抗寒力的排序是:绒叶含笑>马关木莲>小果含笑>状丽含笑>香木莲。由于树种间苗木的抗寒力差异和生长差异,现存5个木兰科树种苗木的主要生长指标排序是:绒叶含笑>马关木莲>状丽含笑>香木莲>小果含笑。绒叶含笑与各树种间其苗木的苗高生长均具有极显著差异或显著差异,地径生长差异也较大;故绒叶含笑是昆明市园林、庭园绿化的一个首选树种,其次是马关木莲、状丽含笑。Study on seedling stage adaptability of 8 Magnoliaceae species in Chenggong county of Yunnan province was conducted from 2004 to 2009.The results of seedling raising of 5 years indicated that Woonyoungia septentrionalis,Michelia ingrata,Manglietia grandis were not adapted to Chenggong.The conservation rank of the remaining 5 species was Michelia velutina〉Manglietia aromatica〉Michelia lacei〉Manglietia maguanica〉Michelia microcarpa.The seedlings of three species with poor adaptability and cold resistance died in frost.The rank of cold resistance of the preserved species was Michelia velutina〉Manglietia maguanica〉Michelia microcarpa Michelia lacei Manglietia aromatica.Owning to the differences of cold resistance and growth performance,the rank of growth indicators of five conserved species was Michelia velutina〉Manglietia maguanica〉Michelia lacei〉Manglietia aromatica〉Michelia microcarpa.There were very significant or significant differences between the height growth and basal diameter growth of seedlings of Michelia velutina and other species,Michelia velutina was therefore evaluated as the top choice species for urban gardening and greening of Kunming city,next came Manglietia maguanica and Michelia lacei.
