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.
石蒜属植物快速繁殖技术研究中,在无菌无性系建立阶段:鳞茎以0.1%HgCl_2消毒10-12分钟效果最好,而叶、根尖、鳞芽等较干净部位选用0.1%HgCl_2消毒7分钟;用三种石蒜属植物的叶片、根尖、鳞芽及带基盘与不带基盘鳞片进行培养,以带基盘鳞片诱导分化效果最理想,鳞芽易培养出芽,但数量有限,而叶片、根尖与不带基盘鳞片均未诱导分化;带基盘鳞片为石蒜属植物快速繁殖最佳外植体,以鳞茎中部3-15层芽诱导率高,较外层稍次之,内部鳞片诱导率最低;选用八等分法、六等分法、四等分法切割鳞茎,六等分法综合效果最好;每外植体带三鳞片培养最为适宜;三种石蒜属植物各自适合的培养基成分不同,换锦花在MS+BA5mg/l+NAA0.1mg/l中培养效果最好,夏水仙为MS+BA5mg/l+NAA0.5mg/l,而白花长筒石蒜在各培养基组合中培养效果均不理想,其适合的培养条件有待于进一步研究。
