Abstract: |
In order to improve higher value-added processing and utilizing levels for sympodial bamboo, the main anatomical characteristics of Bambusa rigida were studied with the microscopic image analysis method. The results show the proportion of parenchyma, fiber, vessel and sieve tube account for 45.5%, 32.3%, 7.0% and 2.2%, respectively. The width, double wall thickness, lumen diameter, length, length-width ratio, double wall thickness-lumen diameter ratio and lumen diameter-width ratio of fiber are 20.271 μm, 16.178 μm, 4.092 μm, 1 901.775 μm, 103.913, 5.715 and 0.193, and the radial width, tangential width and frequency of vascular bundle are 762.978 μm, 640.210 μm and 1.686 N·mm-2, respectively. |
