Wood Quality and Growth of Quercus rubra in Korea: Water absorption, Hygroscopic property

This study was conducted to investigate the relationship between water absorption (or hygroscopic property) and growth rate of rubra oak (Quercus rubra) from 5 different origins of seed (Carleton, Simcoe, Chatham, Bancroft, Unknown). Water absorption at cross section of Quercus rubra was 0.43∼0.92 g/cm2 and the property was not related with growth rate. Overall equilibrium moisture content of rubra oak were 11.35∼11.56% and 15.15∼15.83% at 40℃ with 75% and 90% relative humidities, respectively. There was no relationship between growth rate and moisture content(hygroscopy) in rubra oak. Based on the results, Rubra oak can be classi-fied as a low hygroscopic wood grade, and thus might be a good raw material for furniture productions owing to its superior dimensional stability.
