These transitional stages are the blastogenesis, the first stage from the moment of conception to the implantation or nidation after around 14 days. Secondly, the stage following on from nidation until the moment when the foetus has a viable independent existence, and finally the stage from viable independent existence until the actual birth.

这些过渡阶段是芽基发育,即从受孕到植入或着床的时刻起大约14天的第一阶段;第二阶段从着床开始,到胎儿已经成为可存活的独立的存在;第三阶段从可存活的独立存在到实际出生。

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。

The result showed that twocDNA fragments which expressed at high level both in shoot and radicle representedthe gene encoding beta-D-glucosidase; one cDNA fragment expressed specifically inshoot represented the gene encoding mitochondria HSP60; most clones of MF12 andMF17 fragments respectively represented the chloroplast genes encoding prp22 andprp19 proteins which are two components of ribosomal small subunit; while thededuced amino acid sequence from each exceptional one clone was respectivelyhomologous to CDC5 proteins and vesicle-associated membrane proteins; otherthree cDNA fragments expressed preferentially in shoot had no homologue inGenBank.

结果发现2个在胚芽和胚根中表达量都很高的cDNA片段代表的是编码玉米β-D-葡糖苷酶的基因;一个在胚芽中表达而在胚根中不表达的片段代表的是编码线粒体分子伴侣HSP60的基因;片段MFl2的大部分克隆测序结果是与叶绿体基因组中编码核糖体小亚基蛋白prp22的基因同源,但其中有一个克隆测定的cDNA片段序列推测的氨基酸序列与CDC5家族成员有较高的同源性;片段MF17的大部分克隆测序结果与叶绿体基因组中编码核糖体蛋白prp19的基因同源,而有一克隆测定的cDNA片段序列推测的氨基酸序列与参与信号转导的膜结合蛋白VAP27和VAMP有较高的同源性;另有3个优先在胚芽中表达的cDNA片段未查询到同源序列。

The traits of dedifferentiation and redifferentiation of the explants form H. sampsonii show that the calli the stem and leaf usually form buds at its parietal cells.

These show that the various parts ofthe herb differ greatly in cell initiation and organ differentiation.

研究元宝草外植体的脱分化和再分化的特点结果表明,茎段和叶片启动形成愈伤组织,其不定芽通常发生在愈伤组织的周边区,茎节叶腋的叶隙薄壁组织在激素的诱导下启动、分裂,不形成愈伤组织而直接器官分化成芽原基,并在节结处产生一圈成簇的不定芽,表明元宝草不同部位的细胞启动及器官分化调控存在差异。
