石蒜组培快繁技术研究

目的]建立石蒜组织培养快速繁殖体系。方法]以带基盘石蒜鳞茎为外植体，分别采用六分法和四分法将其分成等份，然后对其进行初代、继代、复壮及生根培养和大棚栽培，确定其最佳快繁体系,结果]带基盘鳞片为石蒜属植物快速繁殖的最佳外植体；六分法切割鳞茎的综合效果较好；石蒜属植物初代培养的适宜培养基为：MS＋BA5mg／L＋NAA0．5mg／L；培养基MS＋BA6mg／L＋NAA0．4mg／L中石蒜的增殖率最高，且石蒜苗生长健壮；培养基MS＋NAA0．5mg／L中石蒜苗的生根率最高（92％），根多且粗壮；出瓶苗在蛭石：珍珠岩=1：1的基质中成活率达85．57％。结论]石蒜属植物的最佳初代、继代及生根培养基分别为：MS＋BA5mg／L＋NAA0．5mg／L、MS＋BA6mg／L＋NAA0．4mg／L和MS＋NAA0．5mg／L。

Study on Rapid Propagation Technique for Lycoris radiate (L'Herit.) Herb

Objective] The study was to establish the rapid propagation system for Lycoris radiate(L'Herit.) Herb.Method] With bulb of L.radiata with BA se as the explants,they were divided with "one divides into six" and "one divides into four".And then their initial,secondary,rejuvenation and rooting culture and the plastic greenhouse cultivation of the tissue culture seedlings were conducted.On the BA sis of that,the optimum rapid propagation system for L.radiata was established.Result] The best explant of L.radi...
