摘要: 为了分析形成菊花花色的色素成分以搞清楚花色形成的机理,该文对17个菊花品种的花瓣进行了花色表型测定、特征显色反应和紫外-可见光谱扫描分析.结果发现:菊花不同花色(黄色、白色、红色、紫色和橙色)品种的色素由类黄酮和类胡萝卜素两大类组成.黄色花主要含有类胡萝卜素和黄酮类化合物;白色花仅含有黄酮类化合物;红色和紫色花主要由花色素苷和黄酮类化合物组成;橙色花的色素包括类胡萝卜素、黄酮类化合物和花色素苷.该项研究为菊花花色素成分的进一步分离和鉴定等工作奠定了基础,同时也为菊花花色的分子育种提供帮助.Abstract: Flower color is one of the most important ornamental characters.The study on flower pigments is significant in exploring the mechanism of flower coloration and molecular breeding of new cultivars.In this paper,the flower color of 17 chrysanthemum cultivars were measured and the specific color reactions and(UV-visible) spectra of flower pigments were performed. The results indicated that flower pigments of chrysanthemum (yellow,white,red,purple and orange) consist of flavonoids and carotenoids. The pigments of yellow flower consist of flavones and carotenoids;there is only flavones in white color flower;the red and purple flowers contain anthocyanins and other flavonoids;the orange is formed by carotenoids,anthocyanins and other flavonoids.This paper provides a reference for the identification of molecular structure of flower pigments and the breeding of flower color of chrysanthemum.
