Abstract
This study was carried out to investigate the effect of charcoal meal application on the quality of the wood. As the results, it was observed that annual ring width of seedlings was wider in the plots treated with charcoal meal than the control plots. Depending on the kind of charcoal, annual ring width was widest in the plot treated with Larix kaempferi charcoal, and then was observed in order of Pinus koraiensis > particle board > Quercus acutissima. Latewood percentage and specific gravity were lower in the plots treated with charcoal than the control plots and lowest in Larix kaempferi charcoal plot among the plots treated with charcoal. Tracheid length was longer in the plot treated with powder charcoal than the control plot but tracheid width was not significantly different from the control plot. The cell wall thickness of earlywood was not significantly different between the plot treated with charcoal and the control plot but that of latewood was thicker in the plots treated with charcoal than the control. Microfibril angle was smaller in the plot treated with granulated charcoal than the control plot. However, there was no significant difference between the plot treated with powder charcoal and granulated charcoal.
