摘要
以40个观赏海棠品种为试材,利用色差计对其4—6月的叶色参数(色彩亮度L*、色彩饱和度C*、色度角h*)进行测定。分析观赏海棠品种叶片色彩在CIELCH色空间中的动态分布格局,探讨品种间的叶色关系及分布规律。结果表明:在4—6月,海棠各品种在色彩参数L*,C*,h*维度方向上呈现规律性分布,整体位点表现为4月最为分散,5月最为集中,6月为局部分散。多数品种亮度L*值和饱和度C*值呈下降趋势,在色度角h*维度方向,大多数海棠品种分布在高h*值的黄色区域,且随着时间的推移,位点整体右移的趋势(h*值增大)。以4月各品种叶色数据进行聚类分析,结果可将40个观赏海棠品种分为3大类,A类群品种的亮度中等,饱和度中等,色度角处在红橙色区域;B类群品种的亮度较低,叶色鲜艳度低于A类,色度角处在红色区域;C类群品种的亮度显著高于B类,饱和度较大,色度角处在黄色区域。
With 40 ornamental crabapple cultivars as test materials,their leaf color parameters（ L＊,C＊,h＊） in April,May,June was measured by a colorimeter,to analysis the dynamic distribution of ornamental crabapple cultivars blade color pattern in CIELCH color space and investigate the relationship between leaf color and distribution of cultivars. The results showed that from April to June,crabapple cultivars in color parameters（ L＊,C＊,h＊） featured a regular distribution,that was overall site as the most decentralized in April,the most concentrated in May,the local dispersion in June; Brightness and saturation of most cultivars had downward trend. In the hue angle direction,most crabapple cultivars distributed in the yellow region,and with the passage of time,the site presented the overall trend right（ h＊value increases）; By cluster analysis of all cultivars of leaf color data in April,40 ornamental crabapple cultivars could be divided into three categories,i. e.,Group A of moderate brightness and saturation,with hue angle in the middle of red orange area; Group B of species of low brightness and color vividness,with hue angle in the red zone; Brightness of Group C significantly higher than that of Group B,with larger saturation and hue angle in the yellow zone.
