对40个杧果品种(系)的花瓣和花药颜色进行数字化描述,即采用Photoshop CS3软件对试材图像进行处理,分别提取花瓣和花药颜色典型色域的CMYK模式参数,通过C、M、Y、K的百分比值确定其颜色。结果表明,用C、M、Y、K的百分比值能较准确科学地表现杧果花瓣和花药的色彩,可以反映品种(系)间差异。通过UPGMA聚类分析,将花瓣和花药颜色分别分成7个类群和4个类群。本研究为种质色彩描述与新品种选育指标提供新的数字化方法。
The colors of petal and anther collected from 40 mango cultivars were digitally described and determined by using Photoshop CS to extract the parameters of CMYK pattern in the typical color region. Results showed that the percentage of C, M, Y, K could represent the colors of petal and anther more accurately and scientifically, and reflect differences between varieties of mango. They were divided into seven and four groups by UPGMA cluster analysis. The research will provide A new digital and scientifical method for germplasm description and new cultivar breeding of mango.
