摘　　要：[目的]筛选适合高寒地区朝鲜黄杨插穗扦插繁殖的最佳ABT浓度。[方法]对沈阳、丹东、大连3个种源地的朝鲜黄杨优选单株进行了扦插试验,研究0(CK)、50、60、70 mg/kg浓度水平的ABT对朝鲜黄杨插穗成活率的影响。[结果]沈阳、丹东、大连3个种源地插穗扦插成活率分别为63.80%、65.37%、63.25%;对不同浓度ABT来说,分种源看,60 mg/mg ABT的插穗生根效果最好,生根率分别为78.70%、73.90%、71.20%,平均达到74.60%。在0.05显著性水平下,种源对插穗成活率无显著影响,不同ABT浓度处理对插穗成活率影响显著。[结论]60 mg/kg ABT处理12 h的朝鲜黄杨插穗生根效果最好。[ Objective ] To screen the optimum ABT concentration for cutting propagation of Buxus microphyllavar. koreana in Alpine Region. [Method]The cutting experiment of preferred individual plant of Buxus microphyllavar. koreana in Shenyang, Dandong, Dalian selected 3 prove-nances were studied, the effects of 0 （CK） , 50, 60 and 70 mg/kg concentrations of ABT on the survival rate of Buxus microphyllavar. koreana cuttings were studied. [ Result] Shenyang, Dandong, Dalian 3 provenances of cuttage survival rate were 63.80% , 65.37% , 63. 25% Respective-ly. For different concentrations of ABT and provenances, the rooting rate of cuttings at the concentration of 60 mg/mg ABT was the best, and the rooting rates were 78.7% , 73.90% and 71.20%, respectively, with an average of74.60%. At 0. 05 significant level, provenances had no sig-nificant effect on the survival rate of cuttings, and the effects of different ABT concentrations on the survival rate of cuttings were significant.[Conclusion ] The rooting rate of 60 mg/kg ABT treated with 12 h was the best.
