IAA·ABT6号对蒙杞1号枸杞新品种硬枝插穗的影响

Effects of IAA and ABT 6 on Hardwood Cuttage of Lycium barbarum Mengqi 1

[目的]筛选对蒙杞1号硬枝插穗促进效果最佳的浸泡溶液浓度。[方法]研究IAA、ABT 6号对蒙杞1号硬枝插穗成活率及根、茎和叶的影响。[结果]IAA和ABT 6号浸泡处理均能提高枸杞硬枝插穗成活率;IAA和ABT 6号互作,对枸杞硬枝扦插苗新枝生长、茎生长具有明显的促进作用;IAA和ABT 6号互作,对枸杞硬枝扦插苗茎、叶和根干重具有明显的促进作用。[结论]当2种药剂分别浸泡或互作浸泡的浸泡液浓度在100 mg/L时,对枸杞硬枝插穗成活率、形态指标和生物量的促进效果最佳。

Objective] To screen the optimal soaking concentration for hardwood cuttage of Lycium barbarum Mengqi 1.[ Method] We re-searched the effects of IAA and ABT 6 on the survival rate of hardwood cuttage, and the root, stem and leaves of Mengqi 1.[Result] IAA and ABT 6 soaking treatment could both enhance the survival rate of hardwood cottage.Interaction of IAA and ABT 6significantly promoted the growth of new branch and stem, as well as the stem, leaf and root dry weight of hardwood cottage of Mengqi 1.[Conclusion] When the soaking liquid concentrations of the two reagents or the interactive soaking concentration are 100 mg /L, the promotion effects were the optimal on the sur -vival rate,the morphological index and the biomass of hardwood cuttage of Mengqi 1.
