Abstract

Eight plantation trees (20 to 26 years old) and 2 natural forest trees (54 and 55 years old) of Masson pine were collected in Forest Farm of Jingshan County, Hubei Province. Tracheid lengths in radial direction first gradually increased and then levels off from pith to bark. It decreased along the stem height. So did the variation in tracheid lengthwide ratio. Basic density at the pith was bigger than that at the bark, and it firstly descended from pith to bark, then gradually asended and finally leveled off. It longitudinally descended from base to top. Cellulose content increased from pith (38. 57%) to near bark (46. 98%) in 22 years old trees. Lignin, pentosan and benzen-alchol extractives contents decreased from pith (28. 35%, 14. 32% and 6. 60%) to bark (24. 70%, 10. 24% and 1. 22%). The juvenile period of the wood was about 14 to 18 years old. Before the period, the tracheid length, length-wide ratio and extracted basic density in trees of natural forests were greater than those in those of plantations. After the period, the results were right converse. Based on variations in the whole tracheid morphological features, basic density , wood chemical composition and the tree growth properties, the range of mature ages for pulpwood were from 15 to 30 years old.
