Abstract

To comprehend the anatomical properties and search for variations of interior wood properties，fibers of Pinus massoniana were studied using a computerized electronic microscope and micrograph analysis system to determine quantitative anatomical properties. Results in the radial position for early wood showed average fiber values of：length 3 711.1 m，width 47.85 m，wall thickness 11.47 m，length to width ratio 76.48，wall thickness to cavity ratio 0.34，and cavity to width ratio 0.76；and late wood revealed average fiber values of：length 3 912.9 m，width 37.30 m，wall thickness 20.45 m，length to width ratio-104.13，wall thickness to cavity ratio 1.73，and cavity to width ratio 0.45. From pith to bark，all fiber morphological parameters gradually increased or increased to a steady state except for the wall thickness to cavity ratio of early wood and the cavity to fiber width of early wood were not significant.，and the cavity to fiber width ratio of late wood decreased. In the relative position，the average fiber values for early wood were: length 3 597.6 m，width 48.83 m，wall thickness 11.70 m，length to width ratio 73.65，wall thickness to cavity ratio 0.35，and cavity to width ratio 0.75；and average fiber values for latewood were：length-3 857.3 m，width 38.71 m，wall thickness 18.82 m，length to width ratio 100.82，wall thickness to cavity ratio 1.33，and cavity to width ratio 0.51. From base to top，all fiber morphological parameters increased at first and then decreased，except for the wall thickness to cavity ratio and the cavity to fiber width ratio were not significant.［Ch，12 fig. 2 tab. 20 ref.］
