研究了青木奈新梢不同枝段(梢段、中段、基段)与不同生长素浸泡处理(1500mg·L-1IBA、1500mg·L-1IBA+1500mg·L-1NAA、100mg·L-1ABT2号生根粉)对其扦插繁殖效果的影响。试验采用随机区组设计,重复3次,以清水处理为对照。对插条萌芽率、生根率、生根数、根生长总量、根鲜重和干重等指标进行了测定分析。结果表明:青木奈嫩枝扦插时,以当年生新梢中上部枝段(枝条粗约0.35～0.40cm)做插条为好;生长素对促进青木奈嫩枝扦插成活有良好的促进作用,其中以IBA+NAA各1500mg·L-1等量混合液处理最好,1500mg·L-1IBA处理次之。
The effects of different auxin treatments (1500 mg · L-1 IBA, 1500 mg · L-1 IBA + 1500 mg · L-1 NAA, 100 mg · L -1 ABT2) on shoots of shoots, shoots, Powder) on the cutting propagation effect. Randomized block design trial, repeated 3 times, with water treatment as a control. The germination rate, rooting rate, rooting number, total root growth, root fresh weight and dry weight of the cuttings were measured and analyzed. The results showed that when young wood shoots were cut, it was better to make cuttings in middle shoots (shoots roughly 0.35 ~ 0.40cm) of the shoots of new year shoots. Auxin could well promote the survival of shoots of young shoots, Among them IBA + NAA 1500mg · L-1 equal amount of the best mixture, 1500mg · L-1IBA followed.
