摘要：Chinese fir and eucalyptus are the important plantation wood species in China. Wood color is a property that can reflect aesthetic features of wood and increase the perceived quality of wood. The color parameters of the two woods and the ability of near infrared (NIR) spectroscopy to assess the color parameters were investigated in this study. The results shown the L*, a* and b* values of Chinese fir were 51.91 similar to 73.33, 6.26 similar to 12.94 and 20.36 similar to 32.04 and that of eucalyptus were 42.30 similar to 62.44, 8.48 similar to 62.44 and 15.07 similar to 25.15 respectively. The excellent related coefficients (r) and lower square error of calibration (SEC) illustrated NIR spectroscopy coupled with multivariate data analysis has ability to rapidly predict the L*, a* and b* values of the two wood species. The use of reduced spectral range has little effect on the quality of PLS models allowing the use of inexpensive and portable spectrometers with lower wavelength region to rapidly assess wood surface color.
