| Abstract: | The variation Pattern of wood tracheid morphology and wood physical mechanics properties of pinus taedaL. was studied in this paper. The mathematical models of the variation pattern of tracheid length, tracheiddiameter, ratio of tracheid length and width, microfibril angle. growth ring width. late wood percentage. cell wallratio and growth ring density were obtained. which can provide the theoretical base of man-made forestintensive management and oriented cultivation as well as the early forecast of wood quality. |
