To improve utilization efficiency,bamboo（phyllostachys pubescens） culms were cut into arc plates for further value-added processes.In this paper,the drying characteristics of bamboo arc plate were investigated.The results showed that the higher the drying temperature,the greater the shrinkage rate and deformation.The average of tangential shrinkage rate was larger than that of the radial shrinkage rate.The tangential shrinkage rate of the outer wall of a bamboo culm was nearly twice of that of the inner wall.When the moisture content was below 5 percent,the drying rate and the shrinkage rate tended stable.Finally,it was observed that as the drying temperature rose,warp,crimping,and split were increased considerably.
