ResumoThe surface color and chemical composition of moso bamboo(phyllostachys pubescens) were observed by steam heating treatment and xenon irradiation.The results showed that color parameters of heat-treated bamboo had changed,lightness L* decreased,chromaticity parameters both a* and b* were plus compared with control group.With higher treatment temperature and longer treatment time,the chemical composition of bamboo surface had changed,Value a* and the overall color change(△E*) increased,to the contrary,b* decreased,which leaded to surface color of heat treated bamboo became darker and darker.With the exposure time increasing,the surface color of control group changed darker while the heat-treated bamboo color turned lighter and color changes became obviously.The overall color change(△E*)of heat-treated bamboo strap surfaces increased,and the change lower than control group.
