| Abstract: | Fiber characteristics of experimental forest of 6-year-old Eucaplyptus cloeziana provenances were studied.The variation of fiber characteristics was analyzed from the trunk direction and radial direction,in order to supply theoretical basis for tree improvement,directional cultivation and rational lumber utilization.The result showed that:The fiber length of different provenances had no significant difference in height along the trunk direction;the fiber length and length-width ratio at 1.3m height became progressive trend as the growth ring,but the fiber cavity-radian ratio became diminishing trend;the variation of fiber length between different provenances was obvious,while the fiber length-width ratio and cavity-radian ratio was not. |
