摘要：Paulownia Siebold et Zucc., a widely distributed native genus, has been commonly used in the furniture. The color of wood is a very important aesthetical property, and it has a fundamental influence on the commercial value of timbers. Therefore, it is critical for forest managers to select elite Paulownia clones based on the color of wood. Eighteen 5-year-old Paulownia clones grown in a hilly area in Hubei Province, China were examined in terms of color values (L*, a*, b*), color difference (ΔE*), and Hunter lab space whiteness (W) using a Chroma meter CR-400. Differences in color parameters among the 18 clones were analyzed and clustered. The results showed that the ranges of L*, a*, b*, ΔE*, and W were 77.19–80.38, 3.60–4.84, 13.79–15.69, 17.92–21.37, and 68.92–72.42, respectively. The color parameters significantly differed among the examined clones. Differential and cluster analyses indicated that clones 204, 605, 702, and 603 had higher L*, W, and lower ΔE*, rendering these as elite clones with superior color properties. ? 2015 Estonian University of Life Sciences.
