Research Abstract

It is known that intervessel pits are occluded by incrusting materials in some hardwood species. This study was carried out to deepen our understanding to this phenomenon. As a result of the survey of 22 Japanese hardwood species representing 20 genera from 20 families, the seasonal incrustation was noted only in Yachidamo (Fraxinus mandshurica var. japonica : Oleaceae). Histochemical examinations showed that the incrusting materials are not a common polysaccharide such as pectin and hemicellulose. The processes of their deposition and disappearance differed between earlywood and latewood in the current-year xylem of Yachidamo.
