Investigation of the Anatomical Structure and Density of the Dalbergia cultrata Wood
摘要
Abstract
The macro structure,micro structure and cell morphology of the Dalbergia cultrata wood were measured and analyzed by using zoom stereromicroscope,digital microscope and image measuring analysis system,and the wood den-sity was determined at the same time.The results showed that the wood color of the D.cultrata wood was purple red;the growth rings were obvious;the wood was scattered with holes,and the combination type of the wood vessels was mainly single vessels,a few were radial multiple vessels,and the shape of the vessel cells was mainly drum-shaped;the wood fiber cells were superimposed,with small cavity and thick,and the cell length-width ratio and wall cavity ratio were 48.84 and 0.81,respectively.The xylem rays were fine,imposed,and homomorphic 2-3 columns,with a height of 5-9 cells and a length-width ratio of 5.17.The axial parenchyma was superimposed,abundant,wing-shaped or concentric paratracheal belt-shaped;the cell length-width ratio was 6.36.Crystalline cells were mostly divided into compartments containing crystals,with as many as 17 crystalline particles.The wave pattern was slightly visible under the eye;the wood grain was straight and the structure was fine.The wood fiber and crystal cells accounted for the largest and smallest proportion of the wood tissue percentages,respectively;the wood tissue percentages could deeply understand the growth of trees and the properties of wood.The wood density was large,and the density,air-dried density and oven-dried den-sity of the wood were 0.85,1.04,0.94 g/cm3,respectively.The above analysis perfected the theory of wood anatomical structure and provided theoretical basis for wood identification and appraisal.关键词
