| 摘 要： | 高加索白杨、N12、N2、N21和SL-1在硬枝扦插生根率、生根数、生根根长和生根指数上存在显著差异。生根能力综合分析表明，N21的硬枝扦插生根率、生根数、生根根长和生根指数指标均优，其中生根根长和生根指数均优于对照品种小黑杨，说明其硬枝扦插生根能力最强。

| Abstract: | The Populus schischkinii, N12, N2, N21 and SL - 1 were significant differences in rooting rate of hardwood cuttings, rooting number, rooting length and rooting index. Thair rooting ability of comprehensive analysis shows that N21 was excellent in rooting rate of hardwood cuttings, root number, rooting length and rooting index, including rooting length and rooting index of N21 are better than the control variety that is P. simonii x P. nigra, it＇s rooting ability of hardwood cuttings is the strongest, show that is better in rooting rate, root number, rooting length and rooting index. |
