Radial Variation of Acrocarpus fraxinifolius Wight & Arn. Wood Structures

Abstract

Acrocarpus fraxinifolius wood from experimental plants was anatomically analyzed evaluating the constituent elements variation from pith to bark. Five 18-year old trees planted in Corupá, State of Santa Catarina were studied. The mean tangential diameter of vessel lumina and fiber length increased from pith to bark. The mean values for fiber width, lumen diameter and fiber wall thickness did not show significant statistical variation.
