Studies on Variation of Poplar I-69 Tree-ring Width and Tree-ring Density

WANG Jia-xiang; XIA Ping; LIU Sheng-quan

Poplar I-69 wood was chosen as the sample, the data of the components of tree-ring width and density were accessed by Tree-Ring Image Analysis System and Tree-Ring Analysis System and the radial and axial variations of the components were analyzed. The results showed that: the radial variation of the density of poplar I-69 increased along with the tree age. The maximum density fluctuated heavy, the minimum density decreased along with increase of the tree age on the whole. The density of earlywood and latewood increased along with the tree age. The radial variation of the tree-ring components was significant within individual trunk, but no difference among trunks. The components of the tree-ring density increased along with the tree height, there into, the tree-ring average density, earlywood density and minimum density increased less, while the tree-ring maximum density and latewood density increased more. Comparatively, the radial variation of the density of poplar I-69 was larger than that of the axial variation.
