摘要：Three wood species were tested at three sections under natural sunlight for a total 733 days. The surface color and gloss of the wood samples was measured at intervals. The results showed that: (1) all woods showed discoloration and loss of gloss after exposure in sunlight, while the discoloration was more obviously; (2) the degrees of color changes of woods were waving with increasing time, which might be caused by the protection and leaching of extractives, oxidization and degradation of lignin; (3) wood species had significant influence on surface color change of wood. Among all woods, the color change of Mabberley (Stereospermum colais) was the most serious, indicating Mabberley was the most sensitive wood to sunlight; (4) for different wood sections, the color changes were different. The degree of color change at three sections decreased in the order: tangential > cross > radial section. (C) 2017 Elsevier Ltd. All rights reserved.
