摘要
[Objective] The research aimed to establish the fast and efficient rapid propagation system for Ampelopsis grossedentata by using the tissue culture method. [Method] Ampelopsis grossedentata stem with the bud was the material,and the influences of different sterilization methods,media and hormone combinations on the in vitro rapid propagation of Ampelopsis grossedentata were studied. [Result] The explant sterilization effect of 75% ethanol dipping 20 s ＋ 0.1% HgCl2 treating 8 min ＋ Tween-80 1-2 drops was better. The optimal medium for the axillary bud induction was B5 ＋ 1.00 mg/L BA ＋ 0.05 mg/L NAA. The optimal multiplication medium was MS/B5 ＋ 1.50 mg/L BA ＋ 0.05 mg/L NAA. 1/2MS ＋ 0.50 mg/L IBA was the best medium for the rooting. [Conclusion] The high frequency occurrence system of Ampelopsis grossedentata in vitro rapid propagation was established. It laid the technology basis for the callus regeneration system,genetic transformation and clonal mutation screening.
[目的]利用组织培养的方法建立快速、高效的显齿蛇葡萄快速繁殖体系。[方法]以显齿蛇葡萄带芽茎段为材料,研究了不同灭菌方法、培养基和激素组合对显齿蛇葡萄离体快繁的影响。[结果]外植体采用75%乙醇浸泡20s+0.1%HgCl2处理8min+吐温-801～2滴灭菌效果较好;腋芽诱导适宜的培养基为:B5+1.0mg/LBA+0.05mg/LNAA;增殖培养以MS/B5+1.5mg/L+0.05mg/LNAA为宜;生根以1/2MS+0.50mg/LIBA的培养基效果好。[结论]建立了一个显齿蛇葡萄离体快繁的高频率发生体系,为其愈伤再生体系、遗传转化及无性系变异筛选奠定了技术基础。
