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: 以10年生6个桉树无性系为试材,采用干燥及吸湿的方法对木材的湿胀性和吸水性进行测定,分析无性系间、单株间、树干高度上的变异规律,并进行相关性分析。结果表明:不同无性系间、不同树干高度部位间材性指标均存在显著差异,不同无性系间和株间木材弦向、径向线湿胀率,体积湿胀率存在极显著差异;不同树干高度对弦向线湿胀率、体积湿胀率有显著影响,但对径向线湿胀率影响不显著;6个无性系中,11号与3号无性系吸水率最高,而14号无性系吸水率最低。相关性分析显示湿胀性指标呈中度至高度正相关,湿胀性指标与吸水性相关度不高,在桉树无性系良种选育时,两个性状指标可以进行独立选择。

     

    Abstract: To study the dry shrinkage and wet swelling properties of large diameter wood of Eucalyptus, and to provide material property data for the utilization of solid wood. The six 10-year-old E. clones were used as test materials, the swelling and water absorption of wood were measured by drying and moisture absorption methods, and the variation rules and the correlation 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 plantswere highly significant differences.but no significant effect on radial swelling rate. Among the six clones, No. 11 and No. 3 had the highest water absorption, while No. 14 had the lowest water absorption. 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 two traits could be selected independently in the breeding of E. clones.
