| 摘要: |
| 研究ABT-1和NAA对掌叶覆盆子枝条处理扦插生根的影响,旨在为掌叶覆盆子大量快速繁殖提供参考依据。试验结果表明:掌叶覆盆子直接枝插无法生根,使用ABT-1和NAA一次浸条处理只能促使愈伤组织形成,只有先后二次浸条处理后才能生根。用ABT-1处理的效果好于NAA,其中50 mg·kg-1处理最为经济; 在50 mg·kg-1 ABT-1处理中,首次浸条2 h,第二次浸条2～3 h效果最好。嫩枝3～8月扦插最好,而老枝3～5月扦插最佳 |

| Abstract: |
| Palmleaf raspberry(Rubus chingii)is one of the important medicinal plants in China. The experiments were conducted in Palmleaf raspberry GAP base of Dexing County,Jiangxi Province,China. The effect of ABT-1 and NAA,on rooting of palmleaf raspberry cuttings was studied to provide references to its rapid propagation in large volume. The results showed that the cutting of palmleaf raspberry without treatment was difficult to develop adventitious roots. Callusing was developed only after treating one time. So the twice treatments with 20 d interval were necessary for rooting of the cutting. Compared with the two auxins,the effect of ABT-1 treatment was better than that of NAA and 50 mg·kg-1 ABT-1 was the best economically. In a serials of soaking time treatments under 50 mg·kg-1 ABT-1,2 h for the first soaking and 2-3 h for the second soaking after 20 d later were the best procedure to increased rooting percentage. In different cutting materials,the best cutting period is from March to August for softwood,and from March to May for hardwood as well. |
