摘　　要：以湖北低山丘陵区5年生品种对比试验林内的19个泡桐（Paulownia）无性系为材料,采用CR-400色差计测定和计算明度（L＊）、红绿轴色品指数（a＊）、黄蓝轴色品指数（b＊）、总色差（ΔE＊）和白度（W）5项材色指标,对其在无性系间的差异性进行分析并聚类。结果表明：19个参试泡桐无性系的L＊、a＊、b＊、ΔE＊、W,分别变化在77.19～80.38、3.60～4.84、13.79～15.69、17.92～21.37、68.92～72.42;在泡桐无性系间的差异性,均达极显著水平。综合无性系间5项材色指标的差异性分析结果和聚类分析结果,204、605、702、603等4个无性系具有明度较高、白度较大、总色差较小等特点,可选为材色性状优良无性系。The experiment was conducted to evaluate color characteristics of fine paulownia clones in the lower hilly region of Southern,five years old clones of 19 paulownia clones were used as experimental materials,and five parameters of brightness,red degree,yellow degree,general chromatism,and whiteness were analyzed by CR-400 color instrument,and the differences were analyzed between clones and clustered clones. The results showed that 19 paulownia clones of L＊,a＊,b＊,ΔE＊and W change in 77.19-80.38,3.60-4.84,13.79-15.69,17.92-21.37,and 68.92 ～ 72.42,respectively,and difference between paulownia clones have reached extremely significant level. The comprehensive analysis and clustered results of 5 indicators of paulownia clones color characteristics,4 clones of 204,605,702,and 603 were optional for color characteristics with taller lightness,whiteness is larger,and the total color difference is small characteristics.
