摘要：Thermal treatment of Phyllostachys pubescen bamboo was performed in a dry oven at seven temperature levels (100-220 A degrees C) for four duration times (1-4 h). The results showed that mass loss increased with increasing temperature and duration, and the maximum reduction reached 29.0 %. The color of heat-treated bamboo was darkened and all three color parameters (L(*)a(*)b(*)) were significantly changed. Modulus of elasticity (MOE) was affected slightly when samples were heat-treated below 200 A degrees C, even a slight increase compared with control samples; but it decreased quickly when samples were treated above 200 A degrees C and the maximum reduction was 20.2 %. However, the Modulus of rupture (MOR) and the contents of holocellulose and alpha-cellulose reduced significantly with increasing temperature and duration when samples were heat-treated above 160 A degrees C, they both strongly correlated with mass loss. It could be confirmed that thermal treatment on bamboo shows an interesting potential to improve bamboo quality.
