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 results indicated that the inhibited concentrations of kanamycin of adventitious bud formation of Helianthus annus were 75 mg/L and 100 mg/L, when the carbenicillin was used in the transformation procedure; the concentrations was 300 mg/L when the growth of agrobacterium could be effectively inhibited. At the same time, the induction and growth of adventitious bud were not remarkably injured.

F. pumila had the strongest capacity to adhere to walls, and it formed a quite good covering landscape by means of a large quantity of adventitious roots. Furthermore, it was tolerant to shade, and the effects of shading on its growth and landscape covering were very small. P. heterophylla had the rapidest growth and covering speed, and it adhered to walls by adhesive discs, but was defoliated in winter or after a long period of shading. The other three vines climbed walls using adventitious roots, and their adhering capacities were all relatively poor. However, E. fortunei still formed a relatively good covering due to its rapid growth and emerald leaf colour. After shading for four months, leaves of F, pumila, C. grandiflora, and P. serpens became thin, and accordingly their leaf weight per unit area significantly decreased. Shading also reduced chlorophyll contents of C. grandiflora and E. fortunei but enhanced those of F. pumila and P. serpens, It did not influence leaf thickness, leaf weight or chlorophyll content of P. heterophylla. Whether shaded or not, the relationship between Pn and PAR for each species could be expressed as y=alnx+b, and furthermore there was a significant (P.01) correlation between them. Pn and LCP values for all five lianas also significant (P.01) correlated. Shading reduced LCP values of P. heterophylla, C. grandiflora and E. fortunei but increased LSP of F. pumila.

结果表明，1薛荔对墙体附着力最强，它依靠大量的不定根吸固在墙体上，形成很好的覆盖效果，而且薜荔耐荫，遮光对其生长与覆盖的影响很小；爬墙虎的生长与覆盖速度最快，它主要依靠吸盘吸固墙壁，但在冬季或长时间遮光后出现明显落叶现象，影响其覆盖景观；其他3种都依靠不定根沿墙面攀援，附着力相对较差，但扶芳藤由于生长较快，叶色终年保持翠绿，也能形成相对较好的覆盖效果；2遮光4个月后，薛荔、凌霄和蔓九节的叶片变薄，相应地这3种植物单位面积的叶片重量都显著减轻；遮光还使凌霄和扶芳藤的叶绿素含量减少，使薛荔和蔓九节的增加，但对爬墙虎的叶片厚度、叶重和叶绿素含量都不产生明显影响；3无论遮光与否，5种植物的Pn与PAR之间的关系都可用y=alnx+b表示，并且都达极显著相关，Pn与光补偿点之间亦呈极显著相关；遮光还使爬墙虎、凌霄和扶芳藤的LCP下降，并使薛荔的光饱和点升高。

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。
