The research aimed to confirm the suitable hormone kinds and level for rooting induction of bulblet in tissue culture seedlings of narcissus.

［目的］确定水仙组培苗小鳞茎生根诱导的适宜激素种类和水平。

Using the tissue cultured bulblet of narcissus cultivar Fortissimo as tested materials, with 1/2MS as the basic medium, 4 conch, of NAA and IBA including 1.0, 0.5, 0.1 and 0.05 mg/L were set up to study the effects of hormone on rooting induction of tissue culture seedlings in narcissus.

方法］以水仙栽培品种Fortissimo的组织培养小鳞茎为试验材料，以1/2MS为基本培养基，设计1.0、0.5、0.1，0.05mg/L 4个NAA、IBA浓度，研究激素对水仙组培苗生根诱导的影响。

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%。

In this paper, induction of callus and regeneration of plants from cuttingpiece of bulb and scalybud-top in fritillaria pallidiflorae were studed, whichhas indicated that in case of adding 2,4-D 1mg/1 and KT 0.1 mg/1, thecallus was induced on the MS medium; in cuse of adding IAA 1 mg/1, NAA0.2 mg/1 and KT 0.1 mg/1, the bulblet from both callus was differentiated.

在加有IAA1毫克/升和NAA0.2毫克/升及KT0.1毫克/升的MS培养基上分化出了小鳞茎。
