Relationship of Wood Basic Density and Anatomical Properties of Eucalyptus dunnii
摘要
Abstract
In order to reveal the variation regularities of Eucalyptus dunnii, the basic density and anatomical properties indexes of E. dunnii in Guangxi Shatang forest farm have been measured and the data were analyzed and compared by means of mathematical statistics. Results indicated that basic density and 5 radiation varia-tions of anatomical characteristics increased rapidly at first and then gentlely increased or reduced from pinch to outward. The variation of 5 parameters except for growth ring width showed highly significant differences within trees and among trees. The indexes of fiber quality traits but fiber wall-lumen reached requirement for paper making. The boundary line of juvenile wood and mature wood was from 8-year-old to 10-year-old. Poly-nomial equations can be could to describe the relationship between basic density and anatomical parameters as well as tree rings.关键词
