This study aimed to observe and to compare the microfibril angle (MFA), crystalline characteristics, and chemical compounds in compression wood (CW), lateral wood (LW), and opposite wood (OW) in the stem wood of Korean red pine (Pinus densiflora). The MFAs of CW, LW, and OW were determined by using iodine staining methods and optical microscopy, while the crystalline characteristics and chemical composition were measured by an X-ray diffraction method and FT-IR spectroscopy, respectively. The CW had the greatest MFA, whereas the OW showed the smallest MFA. The relative crystallinity of CW was the lowest, whereas the OW showed a slightly greater value than that of LW and CW. The crystal widths of CW were slightly smaller than those of LW and OW. The CW and LW showed similar FT-IR spectra in juvenile and mature wood, whereas some peaks from lignin disappeared in the juvenile and mature wood of OW. The MFA of Pinus densiflora was decreased with increasing growth ring number. The relative crystallinity from each part was increased with increasing growth rings, whereas the crystal width showed no radial variation. The FT-IR spectra from CW, LW, and OW in mature wood showed a smaller number of peaks compared to the juvenile wood. In conclusion, the CW, LW, and OW showed a distinct difference in the MFA, crystalline characteristics, and chemical compounds, wherein the MFA and relative crystallinity of CW, LW, and OW showed a radial variation.
