Gerbera plantlets in 125 ml flask received 0, 2.5, 5, 10, 20 ppm Ethrel and 0.01, 0.1, 1 mM 1-aminocyclopropane-1-carboxylic acid to study the effect of ethylene and ethylene biosynthesis through cultured in vitro. The good quality plantlets which had more adventitious roots, no overgown stem, no etiolated plantlets by the addition of 5, 10 ppm Ethrel.

非洲菊(Gerbera jamesonii， Bolus)幼苗於试管内处理以0， 2.5， 10， 20 ppm的益收素及0.01， 0.1， 1 mM的环丙烷氨基羧酸(1-aminocyclopropane-1-carboxylic acid， ACC)以研究乙烯对试管苗之影响及乙烯生合成，结果以5及10 ppm的益收素处理能得到良好品质的苗，为多侧根不徒长，不白化的幼苗。

The 1/2 MS medium supplemented with 1.0 mg·L-1 BA and 0.1 mg·L-1 NAA was very beneficial to the protocorm differentiation and propagation of D.candidum .The highest protocorm propagation index was obtained from the medium containing the activated carbon.The highest root numbers and length were observed in plants growing in 1/2 MS medium containing 0.5 mg·L-1 NAA.

结果与结论：添加20%马铃薯液有利于种胚的萌发，种胚萌发率为79.37%；BA 1.0 mg.L-1和NAA 0.1 mg.L-1最有利于原球茎增殖，培养基中添加2%活性碳原球茎增殖倍数高；NAA有助于试管苗的生根，不同含量NAA以0.5 mg.L-1时试管苗平均根数最多和平均根长最长。

This study investigated the effect of AgNO3 on the in vitro shoot growth and tuberization in the closed and diffusive conditions of two potato Solanum tuberosum L.

在密封或通气条件下，研究了培养基中加入适量硝酸银对马铃薯品种东农303和兰芽试管苗与试管薯的影响。

Furthermore the longer photoperiod was, the later initial time of tuberization of three cultivars was.

从成薯时间和成薯个数上看，相同的光周期下，米拉成薯最早，试管结薯最多，鄂薯3号次之，而大西洋结薯最晚，试管结薯数也最低。

The survival ratio of transplanting reached 100%. The researching of plantlet bulbing of Tuberose showed :It was advantageous to plantlet bulbing on the test tube of 4~6cm high,and pH6.8 , sucrose90g/L concentration of PP33310mg/L.

晚香玉试管鳞茎微繁技术研究结果表明：接种4～6cm高的试管苗，在pH值为6.8，蔗糖浓度为90g／L，PP_(333)浓度为10mg／L的培养环境下最有利于晚香玉鳞茎的形成和膨大。

When all you are doing is looking at colorless solutions being pipetted from one tube to another, and visualizing the results on a gel by radioactivity much later, I find that very dry.

如果你干的全部事情就是眼看着用移液管把无色的溶液从一个试管移到另一个试管，过很久之后才会通过放射的办法在凝胶上看到结果，那我觉得这样太枯燥了。

79Cm and 3. 78cm from M,, M2 to M3 respectively which cannot reach 1/3 height of the control averagely. The seedlings irradiated by 80 X1015 NYcmgave birth to some flower buds without floral shoots and their seed setting rate was lower than that of control obviously. Some M3 plants irradiated by 60X1015 NVcm2grow into bunches which did not appear in M, and M2. Moreover, some phenotypic variations could be inherited stably in subsequent generations. For instance, the dwarf character in the plants treated with the dose of 80 X1015 was stable in inheritance in consecutive three generations.

再次，对不同剂量的低能N~+处理的拟南芥的M_2代试管苗的叶片外植体愈伤组织的诱导和耐盐性进行了比较和分析，发现经不同剂量的低能离子处理的M_2代试管苗的叶片外植体，离子处理影响其出愈率，高剂量处理会抑制愈伤的诱导，但低剂量离子注入对愈伤组织的增殖有一定的促进作用；愈伤组织的耐盐性也与剂量相关，低剂量的耐盐能力比对照的低，但是高剂量处理反而提高愈伤的耐盐性，这间接表明低能离子引起了拟南芥的生理状态的变化，产生了生理效应。

The root inducation rate is 100% on the cotton, pearl rock and agar medium, but the number of root induced is maximum. The average number is 5.47. The young root possess many multistage branchs. The transplant effect also showed pearl rock is ideal substitute for agar.

珍珠岩、琼脂和脱脂棉的生根率都达到100％，生根数以珍珠岩最高，平均5.47条，幼根具多级分枝，试管苗移栽也表明，珍珠岩在地灵试管生根中是琼脂的理想替代物。

Comparing as BA, 0.1mg·L〓 TDZ was more effective in inducing germinating and developing of buds, regenerating prolific caespitose buds via organogenesis, promoting rhizogenesis and activity of root system greatly, as a result, acclimation survival rate was improved significantly. When leaf segments, cut from in vitro plantlets, were placed on MS media containing 0.1mg·L〓 TDZ, adventitious buds regenerated from segments. After transferred to propagated and rooted media, adventitious buds would proliferate and come into full plantlets.

与BA相比，TDZ的细胞分裂素活性至少高出一个数量级，0.1mg·L〓的TDZ能有效地诱导四个基因型芋茎尖的萌动、生长、大量增殖丛生芽，促进试管苗根系发生，将根系活力提高2倍以上，显著提高了试管苗的驯化成活率；浓度为0.01mg·L〓的TDZ能诱导魁芋类型的芋离体叶片切块产生再生芽点，转接后可增殖不定芽并形成再生植株。

It is not known whether flavonoids can be absorbed in amounts sufficient to exert an antiviral effect in humans, and therefore their possible role in the treatment of childhood exanthems remains unknown.

约黄酮类化合物抗病毒行动已观察到的试管实验。41 42 43 44 45 槲皮素，黄酮类化合物之一的，所表现出特别强烈的试管抗病毒特性； 46 47 48但是，一项研究没有找到槲皮素将有利于小鼠的病毒感染。49这不知是否黄酮类化合物可吸收的数额不足以在人体发挥抗病毒效果，因此，他们在治疗儿童exanthems可能发挥的作用仍然不得而知。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
