    基于花色表型的芍药品种数量分类研究

    Numerical classification of peony cultivars based on flower color phenotype

    • 摘要:
      目的花色是进行芍药品种分类的重要依据,而仅基于目测的传统芍药花色分类主观性较强,不能明确界定芍药花色,需要建立更为科学的基于花色表型的芍药品种分类体系。
      方法本研究以175个芍药品种为材料,利用色差仪对其花色表型值进行测定,根据ISCC-NBS色名表示法对各芍药品种的花色进行颜色命名,同时结合系统聚类和生产经验进行归纳分析。
      结果将所测芍药品种花色划分为白色系、黄色系、浅粉色系、粉色系、红色系、紫色系、墨色系、橙色系8个色系。各色系与CIELab表色空间的明度(L*)、红度(a*)和黄度(b*)有良好的对应关系,能够实现对不同芍药品种花色的定量描述,色系分类合理。同时,发现芍药品种花色丰富,且不同芍药品种群的花色有较显著的差异。
      结论本研究对芍药品种的花色进行了科学分类,应用中可直接根据L*a*b*值确认芍药品种的色系,对芍药品种分类和品种鉴定提供了理论依据,为芍药市场流通和科学研究中的花色描述进行了规范,并对芍药花色方面的育种有指导意义。

       

      Abstract:
      ObjectiveFlower color is an important basis for the classification of peony cultivars, but the traditional color classification of peony based on visual measurement is more subjective and can't clearly define the color of peony. It is necessary to establish a more scientific classification system of peony cultivars based on the color phenotype.
      MethodIn our research, 175 peony cultivars were selected to measure the flower color phenotype by colorimeter. Then the peony petal samples were named according to ISCC-NBS Method of designating colors as well as hierarchical cluster analysis and production experience.
      ResultFinally, the peony cultivars were classified into eight groups, including white group, yellow group, light pink group, pink group, red group, purple group, dark red group and orange group. Each color group had correspondence with the L*, a*, b* values of CIELab coordinate, so the quantitative description of the color of different peony cultivars can be realized. It indicated that the classification system was reasonable. What's more, the flower color of the peony cultivars is various and exists obvious difference among different cultivar groups.
      ConclusionThe flower color of peony cultivars was scientifically classified in this study. The color group of different peony cultivars can be confirmed directly according to L*, a*, b* values. It provides a theoretical basis for the classification and identification of peony cultivars and it's a standard for the description of flower colors in the circulation of peony market and scientific research. Also, it's important to breed new cultivars with new colors of peony.
