中文摘要 | 植物葉片表皮上氣孔的類型在近代分類學上扮演日益重要的角色,國外學者曾提出不同之分類方式,並以之探討科(family)級甚或屬(genus)級分類群之分類問題。本文針對台灣產耳蕨屬植物之表皮形態進行比較研究,發現傳統上用於觀察之膠片或指甲油印模法所看到之細胞形狀實際上為角皮層之加厚隆起所形成,而掃描電子顯微鏡之觀察亦支持此一看法。 省產耳蕨植物之角皮層類型依研究結果分為四型,即波狀紋、深波狀紋、深波狀紋而邊緣連成網眼及波狀紋而有肋狀突。此四種類型之分佈情形與Tagawa(1940)及Daigobo (1972)所提出之分類系統並不一致,推測可能係環境控制之形色特徵。 |
英文摘要 | The epidermal morphology of plant leaves are shown to be valuable character in recent plant taxonomy by a multitude of au-thors. Some classifications of stomatal patterns have been drawn up and used in the classification of family or genus rank. A com-parative study on epidermal morphology among the Taiwanese Polyst-ichum was made by the traditional methods, e. g. cellulose acetate imprint method and nail varnish imprint method, arid scanning electron microscope (SEM) in this paper. The "cells" observed by the former methods was found to be the cuticular thickening and proved under SEM. Four cuticular types have been observed in the present study, i. e. undulate, deeply sinuate, deeply sinuate with marginal areolae and un-dulate with laterally marginal enation. Their distribution is not corre-lated with the taxonomic systems when compared with those of Tagawa (1940) and Daigobo (1972). This morphological variation is probably environmentally induced . |
