Study on the rapid Propagation Technique of Lycoris. Herb and get follow results: In the period found of axenic clone 0.1%HgCl2 is the best disinfector to deal with the Lycoris" bulb ,as to neat part, such as root, leave, and bulbil, is fit to use 0.1%HgCl2 antisepsis 7min. And found the best effect is the bulb scale with base. Root, leaf and bulb scale without base all were not inducement adventitious buds. Different position of bulb had different culture effect. 3-15 of middle part of bulb can be induced most adventitious buds but inner and outer of least it. Incised the bulb with three types (pieces of eight, pieces of six, piece of four), and found the type of pieces of six is best to Lycoris mass production. L.sprengeri is fit MS+BA5mg/l+NAA0.1mg/l and L.squamigera is fit MS+BA5mg/l+NAA0.5mg/l, but the medium fit to culture L.longituba haven"t be found.In the period of Subculture-Found of mass production, the most multiplication of adventitious buds in MS+BA5mg/l+NAA0.5mg/l during subculture of L.sprengeri, L.squamigera.
