3年生杂交桉无性系木材密度和生材含水率差异
Differences in Wood Densities and Green Wood Moisture Contents of 3-year-old Hybrid Eucalyptus Clones
摘要
Abstract
In order to provide scientific basis for promotion and cultivation of new hybrid Eucalyptus clones,us-ing fifteen 3-year-old new hybrid Eucalyptus clones as research objects and DH32-28 and DH32-29 as con-trols,wood densities and green wood moisture contents of clones were measured.Results showed that among fif-teen new hybrid Eucalyptus clones,green wood densities,basic densities and green wood moisture contents ranged from 0.977-1.077 g/cm³,0.375-0.516 g/cm³,and 107.95%-169.91%respectively,wood densities of which met requirements for fiber raw materials.There were significant or extremely significant differences in green wood densities,basic densities and green wood moisture contents among clones and parts.There were no significant differences among plants.Along radial direction from pith to outsite,green wood density and green wood moisture content showed trends of increase,while change rule of basic density was opposite.Based on ba-sic density index,DH693-1,E6,DH599-4,DH707A-1,DH696-5 and DH723A-1 clones exhibited superior performances and could be selected as preferred materials.关键词
