Quantitative Classification of Flower Color Phenotype of Different Clematis L.
In order to accurately define the quantity of flower color phenotype in different varieties of Clematis L.,with the calyx petals of 120 Clematis L.varieties in full bloom in the Clematis L.application demonstration base of Jiangsu Vocational College of Agriculture and Forestry as the research materials,the L*,a and b*values were mea-sured with a high-precision grating spectrophotometer,and then the data analysis was carried out.As demonstrated by the results,the 120 varieties of Clematis L.tested could be divided into light purple system,blue-purple system,red-purple system,white system,dark purple system,light red system and light green system through Q-type cluster analysis,but similar color systems could not be completely distinguished.To make the classification more accurate,the ISCC-NBS color name notation was utilized in combination,and a total of 27 color names were obtained.Differ-ent Clematis L.varieties were mostly light purple,medium purple,dark purple and dark purple-pink,and the flower colors were mainly distributed in light purple system,blue-purple system,red-purple system,dark purple system and light red system.In addition,this study also analyzed the distribution characteristics of flower color phenotype by sorting out the range of parameter distributions of different color phenotype,the established database is expected to provide scientifically effective data information for variety identification and flower color breeding.
