Abstract

Wood is a tissue produced by the hypertrophic growth of the cambium in woody plants. Along the mesh's holes in the cambium at the transverse section, nutrients and moisture pass through in the longitudinal direction. At the radial section, which is a cross-section along the radial direction, the pit structure acts as a passage for the horizontal movement of nutrients and moisture to adjacent tissues. This structure varies in shape with different species and could be used as a tool for the identification of wood. This study investigates the identification of carbonized wood found in a damaged vehicle and that obtained near a fireside by observing their pit structure with an electron microscope. After washing and drying the two carbonized samples and subsequently observing them with an electron microscope, the similarity in their pit structures was evident. This similarity suggests that the two samples belong to the same species. Typically, identifying wood species requires a significant amount of time and labor for sample pretreatment. Overcoming these challenges, a method using an electron microscope could identify the species through carbonized wood.
