| Abstract: | This study uses X ray to measure wood density of triploid clones of Populus tomentosa Carr. Based on suitable mathematical model, the distribution of wood density was analyzed by cumputer visible technology. The graphs are direct and clear, and various transformations can be done from different angles, in different colours, for part or entirety demonstrating. This is useful to understand the wood properties. At the same time the paper analyzes the differences and the variation rates of the wood density of \%Populus tomentosa\% triploid clones. |
