This study was conducted to investigate and to compare the anatomical characteristics among compression wood (CW), lateral wood (LW), and opposite wood (OW) in the stem wood of Ginkgo biloba. To analyze the anatomical characteristics, optical and scanning electron microscopy and an X-ray diffraction method were used. The CW showed circular tracheid with angular outline, numerous intercellular spaces, varying of lumen size, slit-like bordered pits, piceoid pits in the crossfield, and a few spiral checks. The LW and OW showed rectangular tracheid, a few intercellular spaces, varying of lumen size, bordered pit and cuppersoid pit in the crossfield. Rays were mainly uniseriate, with a few biseriate rays in tangential section of CW, LW, and OW. The CW and OW showed similar tracheid lengths in the 5th and 10th growth rings; however, the CW was the shortest in the 15th to 20th growth rings. The CW showed the highest ray height and lowest ray number in each growth ring. The MFAs of the CW were greater than those in the LW and OW from both measurement methods. The MFAs obtained from the iodine method were smaller than that of the MFAs obtained from the pit aperture measurements. The CW had the lowest relative crystallinity in each growth ring, whereas the crystal width of the CW was the smallest in the 5th and 15th to 20th growth rings. Consequently, there were some significant differences in anatomical characteristics among CW, LW, and OW in a stem of Ginkgo biloba.
