| Abstract: | The variation Pattern of wood properties of natural Pinus densiflora was studied by growth-ringmethod for analyzing wood properties. The mathematical models for property parameters on tracheidlength, tracheid width. ratio of tracheid length and width. growth-ring basic density, growth-ring width.latewood Percentage and growth Percentage in the radial direction were set up. The results of correlationanalysis showed that except the density. the other six indices are all significantly related to the growth ring. |
