摘　　要：本研究旨在筛选蓝玉簪龙胆扦插繁殖的最优前处理方案。设置不同的IBA浓度对不同部位的插穗进行处理后扦插繁殖,通过其生根数、生根率和生根时间选择出最优的插穗材料和插穗前处理浓度。结果表明:以未形成花芽的侧枝作为插穗,100 mg/kg的IBA处理后平均生根数最多和生根率最高。从生根时间上来看,20 mg/L的IBA处理生后平均生根时间最短,其中以主枝作为插穗比侧枝的生根时间更短。The purpose of this study is to screen the optimal pre-treatment scheme for the cutting propagation of Gentiana vertchiorum.Different cutting materials and IBA concentrations were selected for treatment,and the results showed:when the lateral branches without flower buds are used as cutting materials,treatment with 100 mg/kg IBA can effectively increase the average rooting number and rooting rate,and at the same time shorten the rooting time.
