Abstract
In order to find out the properties, and improve the levels of cultivating and high value-added processing and utilizing for Chinese rattan resources, the Daemonorops margaritae, a Chinas native rattan species was chosen as the research material, the relationship between the fiber characteristics and the growth and development was analyzed with the method of biological anatomy. The results showed that the fiber diameter was 12.041 μm, lumen diameter 6.350 μm, length 990.476 μm, length-width ratio 86.23, double-wall thickness 5.691 μm and wall thickness-lumen ratio 1.05. The fiber had thick wall and small lumen, and the size was different at different positions. The fiber was longer and with minimum diameter at coretex, while the reverse conclusion was at middle height and middle layer between core and coretex of the cane. The wall thickness decreases, and lumen diameter increased with the cane height increasing at axial, i.e. with age of the cane decreasing.
