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。

Two specieses, Lycoris radiate and Lycoris aurea, were selected for the studying of artificial propagation in vitro. A few specieses of Lycoris, from the southeast area of China and part of locations in Japan, were chosen to research their karyotype differentiation and to measure their genetic diversity by ISSR analysis. The results could be summarized as follows.1. The vegetative propagation conditions of Lycoris aurea and L. radiate in vitro was studied by two-scaling. Different illuminate condition had an effect on the bulblet formation rate. To the species of L. radiate, the rate was higher in the state of 16h 800-12001x illumination than in the darkness. The medium also affected the new bulblet formating rate. When the culture was MS medium 0.2 mg/L NAA 4 mg/L 6-BA, the bulblet formationg rate of L. aurea was 220%;at the same time, when the medium was MS 0.2 mg/L NAA 2 mg/L 6-BA, the rate of L.
本研究选择西南部分地区及日本的几个石蒜品种,从细胞学和DNA分子角度,分析了它们的遗传多样性水平和遗传结构状况,对红花石蒜和忽地笑的离体繁殖技术进行了初步研究,得出如下结论: 1 进行了红花石蒜和黄花石蒜双鳞片快速繁殖条件的研究,结果表明:红花石蒜在16小时800-1200 lx光照下比黑暗条件下出芽率要高;黄花石蒜在MS NAA0.2mg/L 6-BA4mg/L下出芽率为220%,红花石蒜在MS NAA0.2mg/L 6-BA2mg/L下出芽率为108%;NAA比IBA有利于石蒜生根;硅藻土显著提高黄花石蒜双鳞片出芽率,活性炭起抑制作用;6%蔗糖浓度有利于红花石蒜小鳞茎增重,MS 6-BA4mg/L NAA0.5mg/L培养基有利于小鳞茎增殖,切割一刀比两刀有利于小鳞茎增殖。
