The lengths of tracheids in Korean red pines from Anmyeondo (AMD) and Sokwang-ri(SKR) were compared to verify a difference according to the growing provinces. For the study two plots (Age classes V and IX) at each province were selected and increment cores (∅12 mm) were extracted from three dominant red pines at each plot. The increment cores were cut year by year considering ealy- and latewood and then macerated in Schurz solution to obtain tracheids. The measurement of tracheid length were fulfilled using 30 tracheids per early- and latewood in each year. For the statistical analysis we only used the measurement data from the mature wood. The correlations between interannual tracheid-length variations of early- and latewood within the same experimental trees were statistically significant. However the correlations between inter-annual tracheid-length variations of early- and/or latewood in experimental trees were not statistically significant. AMD9EW had the longest tracheid length (3.92±0.25 mm), and then AMD9LW (3.86±0.16 mm), AMD5EW (3.78±0.25 mm), AMD5LW (3.71±0.21 mm), SKR9LW (3.48±0.12 mm), SKR9EW (3.34±0.13 mm), SKR5LW (3.30±0.17 mm), SKR5EW (3.16±0.18 mm) were followed. Therefore it was concluded that red pines in AMD have longer tracheids than in SKR. The results could be used to select the most appropriate raw material for the specific pulp and paper products.
