Abstract

Observations of the fiber morphology and basic density of fast-growing Chinese fir in Lin an City, Kaihua County and Qingyuan County of Zhejiang Province showed that at the breast height fiber length increased with the increase of annual ring from the pitch outwards. From the base of a shoot to terminal the average fiber length ( L ) decreased, which varied from place to place, LLin an LKaihua LQingyuan. The ratio of length to width increased with the growth of annual rings. Basic density ( ) at the breast height of the fast-growing Chinese fir waskaihua Lin an Qingyuan. The variation in basic densityat dif ferent height of the same Chinese fir was that there was a greater change at the base and the terminal of a shoot, than at the middle parts. From the pitch outwards, the basic density decreased from 2～4 annual rings, but increased evenly and gradually af ter the sixth annual ring. The difference of hasic density was obvious among the different Chinese firareas.
