- 中文摘要：
本研究對台灣耕地之頑強雜草一水稗等29種，進行葉片解剖及葉綠素 a/b 比值之測定，基於葉片之解剖構造，計得14種雜草具有"Kranz"型式之維管束排列，15種無此特殊排列；其中莎草科（Cyperaceae）之莎草（Cyperus iria L.）及香附子（Cyperus rotundus L.）均具有二層環繞之維管束鞘細包，葉綠體在二層維管束鞘內之分佈方式各異，為其特點。就 14 種型植物中有9種屬於禾本科，莎草科及莧科各有兩種，馬齒莧科有一種。
- 英文摘要：
The leaf anatomy and a/b chlorophyll ratio of 29 species of noxious weeds on cultivated land ofTaiwan were investigated. Based on the leaf anatomy 14 species were listed for having“Kranz”arrange-ment and 15 species were found without it. Among the species investigated were: Cyperus iria L. andCyperus rotundus L. These species of the family Cyperaceae, had two layers of bundle sheath cells. Thedistribution of chloroplasts within the bundle sheath cells varied with the species. Fourteen species of plants include 9 species in Gramineae, 2 species each in Cyperaceae and Amaranthaceae and only one spe-cies in Portulacaceae.
