摘要
对西南地区优良观赏白及属花色色差进行测定和分析,探究其与生长特性的相关性.收集西南地区白及、黄花白及、小白及种质资源,测量表观性状并在标准光源D65下测定花瓣颜色,利用CIELab颜色系统进行分类.结果表明:可划分为紫色、深紫、粉紫、淡紫、粉、淡橙、淡黄和黄色等8个色系.花色色差与花期、株高、花茎高具备显著的相关性,色差评价模型的建立可以为观赏白及属良种选育与亲本筛选提供参考依据.
Abstract
The color difference of excellent ornamental Bletilla flowers in southwest region was measured and analyzed,and its correlation with growth characteristics was explored.The germplasm resources of Bletilla striata,Bletilla ochracea,Bletilla formosana in southwest region were collected,and their apparent traits were measured.The petal color was measured under standard light source D65,and classified by CIELab color system.The results showed that the flower colors were divided into 8 color systems:purple,deep purple,pink purple,light purple,pink,light orange,light yellow,and yellow.There was a significant correlation between the color difference of flower color and flowering period,plant height,and flower stem height.The establishment of a color difference evaluation model could provide a reference basis for the breeding of improved varieties and parent selection of the ornamental Bletilla.
