桢楠和闽楠木材构造特征对比分析研究

Comparative Analysis of Wood Anatomical Structure Characteristics between Phoebe zhennan and Phoebe bournei

  • 摘要: 为了掌握桢楠(Phoebe zhennan)和闽楠(Phoebe bournei)的宏微观构造特征及二者的微观解剖构造的差异,并为木材识别与鉴定提供参考依据,对两种木材的宏观和解剖构造特征进行了对比研究。利用生物显微镜、数码显微镜和Image J图像处理软件等对桢楠和闽楠的宏观和解剖构造特征进行了研究。结果表明,在宏观构造上,二者在材色和纹理上存在着一定的差异,其余宏观特征差异均不明显;在微观构造上,二者导管分子的弦向直径、壁厚的差异较为明显,木纤维的腔径、双壁厚和壁腔比的差异较为明显,木射线细胞宽度(细胞列数)也存在一定的差异,其余解剖特征差异均不明显。

     

    Abstract: In order to identify the macro and micro structural characteristics of Phoebe Zhennan and Phoebe bournei and the differences between them, and to provide reference basis for wood recognition and identification, the study of macro and anatomical structure characteristics of two kinds of wood was studied and compared. By using biological microscope, digital microscope and Image J image processing software, the macroscopic and anatomical structural characteristics of Phoebe zhennan and Phoebe bournei were observed and studied. The comparison results of macro structure showed that there were some differences in wood color and texture between them, but the other macroscopic characteristics had no significant differences. The comparision results of microstructure showed that there were relatively distinct differences in tangential diameter of vessel and wall thickness of vessel, and there were also relatively distinct differences in lumina diameter of wood fibre, wall thickness of wood fibre and wall cavity ratio of wood fibre, and there were also some differences in ray width (column number of cells), other microscopic characteristics had no significant differences.
