【Abstract】 The variation patterns of tracheid morphology and density of Pinus densiflora plantation were studied in this paper. The mathematical models of the variation pattern of tracheid length, tracheid diameter, ratio of tracheid length and width and growth ring density were obtained, which can provide the theoretical base for man-made forest intensive management and oriented cultivation as well as the early forecast of wood quality.更多还原
