木材に対する液体浸透機構の解剖学的解釈 (綜說)

Abstract

This review involves a present anatomical interpretation on the mechanism of liquid penetration into wood, and reveals the followings: 1) There are different two types of mechanism, i. e. flow-penetration and diffuse-penetration, in the so-called liquid penetration into wood. 2) The flow-penetration paths of liquid have been clarified to a certain extent from the results obtained by the microscopical observation. 3) But the diffuse-penetration paths, and formation mechanism and structural detail of the cell wall pits, especially of the bordered pits in coniers, are not yet distinct enough to explain the liquid penetration, since they are beyond observation by the optical microscope.
