| 摘要: |
| 以不同单株刨花润楠为研究对象,研究了不同浓度ABT1、不同穗条处理和黄化作用对扦插成活率和生根率的影响。结果表明：刨花润楠扦插生根的成活率和生根率在不同浓度ABT1、不同穗条处理和黄化处理间分别存在显著或极显著差异。经过200ppm 的ABT1处理后的扦插成活率和生根率分别高达53.0％、39.8%；留半叶的扦插效果明显较好,其成活率和生根率分别比1叶处理提高11.11%～33.77%、26.3%～42.5%；黄化插穗的成活率和生根率分别为45.6%～63.9%、31.5%～54.0%,均明显优于未黄化插穗。 |

| Abstract: |
| The experiment was conducted to study the effects of different concentrations of ABT1 and different spike deals and xanthation on rooting of Machilus pauhoi cuttings. The results showed that: The survival rate and rooting rate of Machilus pauhoi in different concentrations of ABT1 or different spike deals or xanthation were significant or extremely significant difference respectively. The survival rate and rooting rate were 53.0％,39.8%with the treatment of 200 ppm of ABT1. The cutting effects of a half leaf were better, the survival rate and rooting rate of a half leaf increased by 11.11% to 33.77% , 26.3% to 42.5% comparing with that of 1 leaf. the cuttings survival rate and rooting rate of xanthation were 45.6% to 63.9%、31.5% to 54.0%,and were significantly better than that of not xanthation. |
