The results indicated that the best induce medium for bud propagation was B5 + 0.1 mg/L NAA + 3 mg/L 6-BA. The numbers of hormone and nutritious and the period cultured were different in different varieties. The garlic shoot-tip with some bud scale is better for culturing. It can increased the survival rate of virus eliminating seedling and propagate rate.

结果表明，最佳诱导培养基为B5+0.1mg/L NAA+3mg/L 6-BA，但是，激素、营养物质的添加数量以及培养时期不同品种间有差异；剥离大蒜茎尖带一定数量的鳞片为好，其不仅可提高脱毒苗成活率，而且有利于扩大茎尖繁殖系数。

The results showed that NAA at low concentrations 0.1~0.2 mgL^(-1 was more beneficial for root induction, the rate of rooting was up to 100%. 1/4MS was more suitable to deal with the plantlet rooting and form small bulb. The optimal ratio of IBA and AC for rooting was 2.0 mgL^(-1) IBA+0.1%AC. The in vitro growth of plantlets were the strongest, and survival rate was 100% after incubating at 4℃ for 4 weeks when the diameter of bulblet was ≥9 mm.

结果显示；低浓度的NAA0.1~02mgL^(-1有利于根的诱导；生根率均达100%；大量元素1/4MS处理更适合试管苗的生根和小鳞茎形成；"IBA+AC"处理最佳组合是2.0mgL^(-1) IBA+0.1%AC；鳞茎直径≥9mm的试管苗去顶4℃低温冷藏4周；移栽后喷施1/2MS营养液；长势最好；成活率达到100%。
