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.

Sequences analysis revealsthat these 54 strains have as high as a 99% similarity in 16S rRNA gene level. Allthese 54 strains could be classified into six subgroups according to six differentregions on full-length 16S rRNA gene. Even if the regional differences are not evidentto distinguish B. thuringiensis from B. cereus, however the data of the 16S rRNA genesequences will serve to broaden the database for Bacillus, and provide someinformation for the classification of genus of Bacillus. Additionally, seven B.

本研究利用通用引物,对54株苏云金胞杆菌和蜡状胞杆菌的16S rRNA基因进行测序,并对所得到的序列进行简单的分析,发现苏云金胞杆菌和蜡状胞杆菌的16S rRNA基因的相似性很大,大约为99%,在其全长含有6个区域的不同,根据这6个区域将Bt和Bc分成6个亚群,而Bt和Bc在不同亚群之间交替存在,说明16S rRNA基因上的差异不足以区分Bt和Bc。

本文分别从羊草地下库的季节动态、高有性生殖分配对库的影响、不同基株密度条件下库及所生成子株的数量变化、根茎顶碳氮化合物在克隆生长中的重要作用以及不同阶段遮光处理对库数量的影响方面对羊草进行研究,得出的主要结果和结论如下:(1)每种类型都有不同的起始产生时间。

The results showed:①Anthocyanin content in mature fruits was 132170 U·g-1FW in bud mutation which was very significantly higher than that in'Ralls'(49140 U·g-1FW);②Activities of PAL and UFGT were almost the same between the two materials, but CH I and DFR activitieswere significantly high in bud mutation, which were related to the increase of anthocyanin levels in the mutant;③Bagging treatment inhibited anthocyanin synthesis of bud mutation. But anthocyanin content had significantly increased after removing the bags. Activities of CHI and UFGT increased rap idly and were much higher than those in the control after the bag removal. The increase was consistentwith the imp rovement of anthocyanin levels.
