Title: Morphological differences of Fargesia yunnanensis fibers
Abstract: Fargesia yunnanensis is one alpine bamboo that belongs to Fargesia Franchet,which has no reports on variation pattern of fiber properties so far. Morphology of F. yunnanensis fibers was examined and analyzed systematically to investigate the growth change of F. yunnanensis fibers by adopting the method of fiber isolation,so as to provide a theoretical foundation for the rational development and utilization of this bamboo. The results showed that fiber length ranged from 0.50 to 5.18 mm averaging 1.74 mm,fiber width ranged from 5.70 to 52.00 μm averaging 19.98 μm,the fiber length to width ration ranged from 18.86 to 361.71 averaging 92.80,fiber cell wall thickness ranged from 0.80 to 416.00 μm averaging 14.17 μm,fiber cell cavity diameter ranged from 0.30 to 390.00 μm averaging 5.33 μm,and the fiber cell wall to cavity ratio varied from 0.03 to 109.00 averaging 3.11. The change for average fiber length in mature bamboo culms was middle bottom top,and average fiber width showed an analogous rule to average fiber length. Also,the change for average fiber wall thickness in one-and two-year-old bamboo culms was bottom middle top and in three-year-old bamboo culms was top middle bottom; fiber lumen diameter showed an analogous rule to fiber cell wall thickness. Thus,age and the bamboo longitudinal location had a strong influence on fiber characteristics. [Ch,1 tab. 10 ref.]
