Abstract

To explore the color index’s differenece law of Toona sinensis wood from different provenances, we use 20 years old wood which is from Jiaozuo, Luoyang, Shangqiu, Nanyang area of Henan Province as the raw materials to survey and analyze the color index L*a*b* and chromatic value. The results are as follows: The greater color index a*, the greater the chromatic value. When combined with the actual visual perception, the chromatic value is closer to human visual perception than color index a*, which can express the change of red degree of Toona sinensis wood more comprehensive.

Keywords
