摘　　要：为合理利用和开发建始槭资源,在多年观测和实践基础上,总结了建始槭的物候特征和变色特性,提出了建始槭的播种和扦插等繁育技术。建始槭3月下旬到4月上中旬展叶并开花结果,叶片变色时间为10月下旬至11月底,落叶时间为11月初至12月上旬;建始槭为种子浅度休眠槭树,低温沙藏处理可以解除其休眠,提高种子播种的出苗率;采用浓度100 mg·L^(-1)的IAA溶液对当年生、半木质化插穗浸泡1 h生根率为86%,生根效果较好。In order to rationally develop resources of Acer henryi,the phenology and color change characteristics of Acer henryi were observed and summarized for many years,and the seedling and cutting experiment were explored.The results showed that late March to mid April,Acer henryi Pax were periods for leaves development,blossom and fruits bearing.The discoloration was from late October to the end of November,and the defoliation was from early November to early December.As a kind of shallow dormancy maples,Acer henryi Pax's dormancy could be removed by low temperature and wet sand stratification treatment which improved the seedling rate.IAA solution of 100 mg·L^(-1) was applied to Acer henryicuttings for 1 hr.treatment and the rooting rate could reach 86%.
