This study investigated and compared the anatomical features of six Quercus species grown in Korea, Quercusvariabilis, Q. serrata, Q. mongolica, Q. dentata, Q. aliena, and Q. acutissima. The anatomical and non-anatomical features were evaluated following the International Association of Wood Anatomists’ list for hardwood identification. In the anatomical features, Q. variabilis and Q. acutissimaexhibited similar latewood vessel arrangements and paratracheal axial parenchyma, featuring diagonal and/or radial arrangements and showing vasicentric, confluent, and unilateral parenchyma. In contrast, dendritic-to-diagonal patterns of vessels with angular outlines were observed in the latewood of Q. serrata, Q. mongolica, Q. dentata, and Q. aliena. Concerning the non-anatomical features, all species showed a darker heartwood color than sapwood, with color variations. Q. variabilis had heartwood–sapwood colors similar to those of Q. acutissima, while Q. mongolica and Q. aliena presented similar heartwood–sapwood colors. All species did not show fluorescence in the heartwood fluorescence and fluorescence in the ethanol extract tests. Only Q. serrata exhibited bright blue fluorescence in the water extract and a weak positive reaction in the froth test. Each species had different colors in both water and ethanol extracts, and the water extract of all species was darker than that of the ethanol extract. Furthermore, a positive reaction in both heartwood and sapwood of the chrome azurol-S test was found between Q. variabilis and Q. acutissima. The burning splinter test revealed that only Q. acutissima was transformed into charcoal. In summary, the differences in anatomical and non-anatomical features of six Quercus species grown in Korea can be used to identify these species.
