摘　　要：[目的]对阅瓣含笑在黄淮地区的引种选育进行研究。[方法]在河南省上蔡县引种优良常绿阔叶树阔瓣含笑，通过3年的野外露天越冬驯化后选择出性状优良的单株，将抗寒树种改接于辛夷之上进行优树无性繁殖，调查其嫁接成活率、越冬保存率、植物学性状、物候期、苗高生长状况。[结果]新品种耐寒性较好，越冬保存率达98％，抗旱、抗病虫害能力也比较强，观赏价值高，花期长达4个月；采用带项芽的接穗改接到辛夷上适应了碱性土壤；苗高生长从每年的4月底开始，到10月底基本停止生长，6月底～8月底是其高生长关键时期。[结论]阔瓣含笑的引种选育对解决黄淮地区常绿耐寒阔叶树种稀少的问题具有重要的现实意义。[ Objective] The introduction breeding of Michelia platypetala in Huang-huai region was studied. [ Method] Michelia platypetala was introduced to Shangcai County, Henan Province. The seedling of grafting survival rate, preserving rate and physiological traits were investigated. [ Result＇] New variety has good cold resistance. The ability of fighting drought ＆ diseases was strong ,the preserving rate could reach 98%. Michelia platypetala was a plant with high ornamental value and longer flowering phase. Seedling grew from the end of April of each year to the end of October. The end of June to the end of August was the critical period of seedling high growth. [ Conclusion ] The introduction breeding of Mich- elia platypetala has important practical significance on solving the problem of few evergreen broad-leaved tree species for Huang-huai region.
