초록
세포간층 lignin은 2차벽 lignin(end-wise-polymer)에 비해 축합도가 높으며 guaiacyl type의 phenol성 수산기등 말단기를 많이 갖는 2차벽 lignin보다 저분자량의 bulk polymer형 lignin이다.
The chemical characteristics of lignin in the differentiating xylem were investigated and compared with those of mature-wood. The compound middle lamella lignin deposited in the early stage of lignification of cell walls in the softwood(Larch) as well as the hardwood(Birch) was confirmed to be the so-called guaiacyl-type lignin and was found to have a relatively larger content of phenoxy hydroxyl group as terminal units and to be more abundant in condensed-type structures like as phenylcoumaran structures compared with mature-wood lingin.
