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 characteristics of clonal growth and resources sharing were important to keep stability of community. The transpiration and the stomatal conductance of stolon with and without adventitious roots were same. But the water potential of stolon without adventitious roots was higher than that with adventitious roots.

臭柏克隆生长和资源共享特性在维持群落稳定中起着重要作用，来源于同一上级枝的匍匐茎，有不定根的和无不定根的日平均蒸腾速率和气孔导度没有差异，但无不定根匍匐茎的叶水势比有不定根的高。

In the process of root cutting, the root accumulated a lot of soluble sugar and soluble protein, which provided material and energy for the cell differentiation. As root differentiating, soluable protein was continuously used up. During 10 to 20 days, the content of soluble sugar and soluble protein in the basipetal top and end of rootkept comparatively stable, then declined as adventitious buds and roots growing. 40 days later, they kept invariable, because the newly formed bud can photosynthesize and the newly formed root can absorb nutrient from outside. The dynamic balances of endogenous hormone regulate adventitious buds and roots of the root. During callus growing and adventitious bud differentiating.

上部根段在细胞分化前期积累了大量的可溶性糖，为后期的分化提供能源物质，同时积累了大量的可溶性蛋白质，为愈伤组织的产生提供能源，而后随着分化，可溶性蛋白质不断被消耗。10～20d根段上部及下部的可溶性糖、可溶性蛋白质含量保持在相对稳定的水平变化不大，后期随着不定芽及不定根的生长下降较快。40d后，新形成的芽已经能够进行光合作用，新形成的根也可从外界吸收营养物质，可溶性糖、可溶性蛋白质含量基本保持不变。

adventitious root：不定根

不定根(adventitious root)的形成是植物发育生物学中一个重要而基本的问题,对离体繁殖也同样具有重要意义. 不定根形成经历了脱分化和再分化的过程,是通过基因调控发生的. 基因功能的执行体-功能性蛋白在此过程中起着重要的作用.
