To find out the optimal method to preserve good quality of mother plant with confused genetic backgrounds and to produce seedings of Senecio hybridus effectively and rapidly,in vitro culture and high frequency propagation of Senecio hybridus was studied by means of using stem-segment with single bud as explants.

为探索瓜叶菊杂合体母株优良性状的保存方法，以便快速有效地进行瓜叶菊种苗的生产，以瓜叶菊5个不同花色母株的单芽茎段为外植体进行了离体培养与快速繁殖研究。

Firstly in this paper human mandibula was scanned by spiral CT. Then the data from CT was import into software (MIMICS 7.10) to reconstruct 3-D digital model. Software (Surfacer 10.5) was used to remove useless points , smooth the curves and output the STL file. The file was input into the rapid prototyping system, and was converted to slice format.

本研究首先用螺旋CT扫描离体人下颌骨，得到断层图像数据不经任何转换直接输入MIMICS软件进行三维重建，得到CAD三维数模，输入Surfacer软件除去杂点干扰，平滑曲面后，保存为STL文件，输入SLS快速成形系统通过激光烧结精铸蜡粉所制作的人下颌骨复制体，其形态、大小及结构与下颌骨实体标本基本一致。

Variation of tetraploidy was observed among the regenerants from culture of immature cotyledons,cotyledons and leaves of melon seedlings.

RESULTS The calculated human skin permeability coefficients of 22 model drugs in vitro or the R values (R=absorbed/unabsorbed) of 17 drugs in vivo are in good agreement with their observed values.

结果 22个模型药物离体透过人皮肤的渗透系数和17个模型药物在一定时间内在体透过人皮肤的透过比的计算值和实测值均相符。

The results were as follows: 1.Inoculated on the induction medium at the late uninucleate stage,the microspores could initiate embryogenesis by first divisions in both symmetric and asymmetric patterns,but the former was predominant.

通过观察玉米小孢子胚胎发生的细胞形态学特征，发现：离体培养条件下单核后期的花粉可以通过均等分裂和不均等分裂两条途径形成胚状体，与前人的研究结果一致。
