Abstract

To better protect and utilize Tsoongiodendron odorum plantations，fiber morphology，micro fiber silk angle，and basic density were studied for 27-years-old Tsoongiodendron odorum plantation wood. A cluster analysis is also employed. Results showed that: the average fiber length is 1 354.23 m，width is 27.08 m，lumen diameter is 17.69 m，and the length/diameter ratio is 51.75. Vertical variation patterns of fiber length，width，lumen diameter，and fiber lumen ratio are similar，presenting a gradual increase upward along the trunk，to a certain height and then again slowly becoming smaller. Vertical basic density variation gradually decreased upward along the trunk. With radial variation for all parameters increasing gradually from the pith outwards and becoming stable after a certain number of years. The average micro fiber silk angle is 10.45，and its radial variation from the pith outwards first increased rapidly and then diminished quickly，to a certain age． This is followed by slowing and gradually becoming more stable. The average basic density is 0.417 gcm-3，whereas radial variation from pith outwards increased， decreased，and then increased. In addition，the cluster analysis showed mature material is limited to material up to 10 years of age.［Ch，4 fig. 3 tab. 11 ref.］
