The results of character evolution history reconstruction shows the SC in PT and AD clade might be a homoplasy character; also, the SC in PT clade might have multiple origins. SC in Pteridaceae has some special characteristics:(1) the cell long axes usually run parallel to the lateral veins;(2) Most of Pteris and Adianum species have VSC only in lower epidermis;(3) Species have ISC also have VSC.(4) Presence of spicular cells is highly correlated with the long veinal epidermal cells. Species have type III silica deposition type usually have longer and narrower veinal epidermal cell compared with ordinary epidermal cells; Species have type IV silica deposition type also have long epidermal cells, but not significantly different from ordinary epidermal cells.
本实验中亦发现凤尾蕨科之矽异形细胞具有几项特色:(1)矽异形细胞之长轴多与叶片侧脉方向平行(2)发现多数铁线蕨属以及凤尾蕨属植物仅下表皮具有脉上矽异形细胞;(3)具有脉间矽异形细胞的种类会同时具有脉上矽异形细胞;(4)长条形的侧脉上表皮细胞与矽异形细胞具有相关性,仅具脉上矽异形细胞的分类群之脉上表皮细胞均较一般表皮细胞细长;具有脉间矽异形细胞之物种之脉上表皮细胞亦为长条形但形态与一般表皮细胞常无明显形态差异。

The leaf epidermis structures of 6 species of Rhododendron had been observed under LM and SEM. The results show that all share together common features as follows: the leaf blades are typical back-abdomen bifacial types, the upper epidermis are formed by two or three layer bigger cells which inside layer cell is bigger than outside one, and the upper epidermis are covered with thicker cuticle.
利用光学显微镜和扫描电子显微镜观察了6种杜鹃属植物的叶片结构,结果表明,它们具有共同形态结构特征:典型的异面叶,上表皮由2~3层细胞组成,内大外小或内、外等大,有较厚的角质膜,无气孔器分布;下表皮均由1层细胞组成,排列紧密;栅栏组织由2层以上长柱形细胞组成,排列紧密;海绵组织细胞较短,排列较疏松,细胞间隙较大;均有表皮附属物。

After discussion of the relationship among idioblastic cells,tolerance to abiotic stress and betaine,the author thought the reason of transgenic plants having an increased number of idioblastic cells was that BADH was introduced and much betaine might be synthesized.

In order to know the evolutionary relationships between false vein, ISC, and VSC in Pteridaceae, 19 grnera and 82 species in Pteridaceae were sampled in this study; silica deposition types, ordinary epidermal cell morphology and veinal epidermal cells morphology of these species were surveyed. On the other hand, a convenient method was developed for this goal. In this method, a tabletop SEM with backscattered electron detector accompanied by post-cooling method was used.
为进一步探讨凤尾蕨科假脉、脉间矽异形细胞与脉上矽异形细胞之间的关系及其於凤尾蕨科内的演化,本论文选取19属82种的凤尾蕨科植物,观察其叶表面之二氧化矽堆积型式、一般表皮细胞形态以及脉上表皮细胞形态;同时,也开发出利用侦测背向散射电子之桌上型扫描式电子显微镜配合后冷却技术(post-cooling method)之快速检测法,该方法利用背向散射电子讯号强弱与平均原子数(average atomic number, Z number)之相关性得到矽异形细胞与一般表皮细胞具有明显对比之影像。
