Comparative Wood Anatomy of Stem and Root in Lindera erythrocarpa Makino

Abstract

Stem and root of Lindera erythrocarpa were described and compared in the wood anatomical aspects. Root wood ap-pearedto differ from stem wood in the qualitative features of growth ring boundary, extraneous materials in vessel ele-ment and ray parenchyma cell, outline of ray, and sheath cell. In the quantitative features, there were differences be-tween these two tissues in vessels per square millimeter, tangential diameter of vessel lumina, length of vessel element, and width of ray. These wood anatomical differences between stem above ground and root below ground were thought to be attributed to their different growth environments.
