摘　　要：通过消毒和不同浓度ABT1号生根剂对3个品种彩叶桂插穗进行处理试验,试验表明消毒是彩叶桂扦插育苗的一个重要环节,用50%多菌灵1000倍液对3个品种彩叶桂插穗进行消毒处理,其扦插生根率均比对照有明显提高,提高值均达25%以上;ABT1号生根剂对3个品种彩叶桂扦插生根率和生根数影响差异均达极显著水平,其中采用浓度为0.3 mg·L^(-1)的ABT1号生根剂处理插穗,‘云田彩桂’、‘珍珠彩桂’、及‘银边彩桂’3个品种彩叶桂生根效果均最佳,其生根率、生根数分别为(97.5%、5.4条)、(95.0%、5.6条)、(94.2%、4.6条)。The treatment of the cuttings of three colorful leafy laurel species was conducted by disinfection and dipping in the rooting agents of different concentrations of ABT1.The results showed that disinfection was an important part of culturing the cutting seedlings of Osmanthus fragrans Colour Group.Using 1000 times solution of 50%carbendazim to disinfect the cuttings of three species of Cinnamomum burmannii,the rooting rate of cuttings was significantly higher than that of the control,and the value was increased by more than 25%.The ABT1 rooting agent had extremely significant effects on the rooting rate and rooting number of 3 osmanthus varieties.The cuttings were treated with ABT1 rooting agent at a concentration of 0.3 mg·L-1,and the rooting effects of ‘yun tian caigu＇,‘zhenzhu caigu＇,and ‘Yinbian caigu＇were the best,and their rooting rates and number of rooting were（97.5%,5.4）,（95.0%,5.6）,（94.2%,4.6）,respectively,for the three varieties.
