Radial Variation Analysis of Fibers on Nine Eucalyptus Clones
In this study,wood dissection was used to determine the fiber length,fiber width,fiber double wall thick-ness,length to width ratio,wall cavity ratio and cavity diameter ratio of 9 Eucalyptus,and the variation of these char-acteristics in the radial direction was analyzed.The results showed that the variation ranges of fiber length,width,double wall thickness,aspect ratio,wall-cavity ratio and cavity diameter ratio of 9 clones were 899.74-1 038.08μm,17.41-20.77 pm,8.07-12.13 μm,44.15-60.07,0.96-2.04,0.41-0.57 respectively.DH33-9,LEI9,DH32-22 could meet the fiber raw material requirements.The aspect ratio of clone DH33-9 was＞35,wall-cavity ratio＜1,can be used as high-quality fiber raw materials.
