10年生桉树无性系木材湿胀性与吸水性变异研究
Variation of Swelling and Water Absorption in 10-year-old Eucalyptus Clones Wood
摘要
Abstract
The six 10-year-old Eucalyptus clones were used as test materials,the swelling and water absorp-tion of wood were measured by drying and moisture absorption methods,and the variation rules and the correla-tion clones,individual plants and trunk height were analyzed.Results showed that the different clones and trunk height parts were significant differences,the woodtangential and radial swelling and volume swelling rate among different clones and plants were highly significant differences,but no significant effect on radial swelling rate.Among 6 clones,No.11 and No.3 had the highest water absorption,while No.14 had the lowest water absorp-tion.Correlation analysis showed that the index of swelling was moderate to highly positively correlation,and the correlation between swelling and water absorption was not high,so the 2 traits could be selected independently in the breeding of Eucalyptus clones.关键词
