摘　　要：以紫叶小檗等11种城市绿化树种为试材,对其插穗用不同生根剂处理,并调查其生根率。结果表明:1)粉花溲疏、火焰柳、芽红红瑞木扦插繁殖时,用1 000 mg/kg吲哚丁酸(IBA)对插穗进行浸蘸处理,生根率较高;2)用IBA对插穗进行浸蘸处理,在药剂浓度0 mg/kg^1 000 mg/kg范围内,插穗生根率随浓度增大而升高,大于1 000 mg/kg时,插穗则出现药害,生根率下降。Using 11 greening plant species （for example purple leaf barberry） as test materials, their cuttings were dealt with different rooting reagent solution to induce root. The results showed： 1） Fenhuasoushu, salix cv. flame, and Cornus alba with red bud cuttings show high rooting rate dipped in solution 1 000 mg/kg of IBA; 2） At range of 0 mg/kg-1 000 mg/kg of IBA, cutting rooting rate increases with IBA concentration. While more than 1 000 mg/kg of IBA concentration, cuttings will be presented phytotoxicity symptoms.
