摘要
[目的]筛选适合白蜡嫩枝扦插繁殖的最优条件。[方法]以‘京绿’绒毛白蜡(Franxinus velutina‘Jinglü’)、‘雷舞’窄叶白蜡(F.angustifolia‘Raywood’)和‘京黄’洋白蜡(F.platyphylla‘Jinghuang’)3个品种的当年生枝条为试验材料,采用正交试验设计,研究树种、激素种类、处理浓度和浸泡时间4个因素对插穗生根的影响。[结果]树种是影响白蜡插穗生根率、生根量、根长和总根长的主导因子,白蜡嫩枝扦插的最佳组合为A_1B_3C_3D_3,即‘京绿’绒毛白蜡+ABT_1+200 mg/L+浸泡60 min。[结论]该研究可为白蜡的快速繁殖提供科学依据。
[Objective]To select the optimum conditions for softwood cutting propagation of Fraxinus chinensis.[Method]The current-year bran-ches of Franxinus velutina"Jinglli",F.angustifolia"Raywood",F.platyphylla"Jinghuang"were used and the orthogonal experiment was em-ployed to investigate the effect of species,hormone types,concentrations and soaking time on the rooting of cuttings.[Result]Results showed that tree species was the dominant factor in rooting rate,root number,root length and total root length.The best treatment combination for cutting of Franxinus Tree was Franxinus velutina 4 Jinglli5 Fraxinus+ABTj+200 mg/L+soaking 60 min.[Conclusion]This study can provide scientif-ic basis for rapid propagation of Fraxinus chinensis.
