韓國産 木本植物에 對한 系統分類學的 硏究 : 녹나무科 植物뿌리의 木部解剖 Anatomy of Lauraceous Root Wood = Systematic Studies on Some Korean Woody Plants

국문 초록 (Abstract)

韓國産 녹나무科 植物 6屬 13種의 뿌리 木材의 解剖學的 形質을 系統分類學的으로 檢討하였다. 이科의 植物은 原始被子植物群보다는 훨씬 特殊化된 形質을 갖추고 있으며 이런 形質들은 1) 大部分 單獨分布또는 약간의 放射複合分布導管 2) 全種에 걸친 大部分의 單穿孔과 部分的인 階段狀 穿孔板 3) 導管要素 末端壁의 완만한 斜角 4) 大體로 導管側壁上의 互狀壁孔 5) 全種에 걸친 伴管主軸柔組織 6) 異性 Ⅱ 또는 Ⅲ型 放射組織 等과 같다. 穿孔板과 主軸에 對한 導管 末端壁의 角度로 볼 때 本科의 特殊化 順序는 후박나무屬→참식나무屬→생강나무屬→녹나무屬→육박나무屬→가마귀쪽나무屬의 順으로 特殊化되어 진것으로 思慮된다.

Anatomical characters of the secondary xylem in roots of Lauraceae, including 6 genera and 13 species grown in Korea, were studied systedmatically.
Lauraceous members studied anatomically possess characters of the secondary xylem that are in the main more specialized than those found in the primitive angiosperm families. The specialized characters are as follows;⑴ mostly solitary pores with some radially multiples, ⑵ mostly simple perforation plates and partially scalariform perforation plates in all species, ⑶ slightly oblique end wall of vessel element, ⑷ prdominantly alternate intervascular pitting, ⑸ paratracheal axial prenchyma in all species, ⑹ beterogeneous Ⅱ or Ⅲ vascular rays.
It is considered that the series of specialization in this family from the perforation plates and angle of end wall to the vessel axis is as follows; Machilus→Neolitsea→Lindera→Cinammomum→Iozoste→Litsea.
