A method to more easily separate vascular bundles and parenchyma was investigated for the purpose of proposing a sustainable and advanced utilization of oil palm trunk (OPT). In addition, particleboard made from vascular bundles was produced as one of the effective ways to utilize the obtained vascular bundles. The following results were obtained. A Zephyr rolling equipment was used for separation, and it was found that the vascular bundles could be easily separated with the veneer in a dry state. SEM observations showed that the vascular bundles could be separated while maintaining the tissue structure. However, some parenchyma remained on the surface of the vascular bundles. The presence of starch was also confirmed within the parenchyma. Particleboard was produced using the separated vascular bundles. The MOR and MOE of the three-layered particleboards with long vascular bundles obtained by Zephyr treatment were about 74.2 MPa and 7.3 GPa, respectively, which are much higher than those of previous wood materials made from OPTs. These results may be the result of extracting the potential of vascular bundles.
为了提出油棕树干（OPT）可持续和先进的利用方法，研究了一种更轻松分离维管束和薄壁组织的方法。此外，作为利用所得维管束的有效方法之一，生产了由维管束制成的刨花板。获得了以下结果。使用微风滚动设备进行分离，发现维管束在干燥状态下可以很容易地与单板分离。扫描电子显微镜观察表明，维管束可以在保持组织结构的同时被分离。然而，一些薄壁组织残留在维管束表面。在薄壁组织中也证实了淀粉的存在。使用分离出的维管束生产刨花板。通过微风处理获得的带有长维管束的三层刨花板的抗弯强度和弹性模量分别约为74.2兆帕和7.3吉帕，远高于以前由油棕树干制成的木材材料。这些结果可能是挖掘维管束潜力的结果。
