摘　　要：为给鉴别北美海棠品种以及果色育种提供参考,以18个北美海棠品种幼果果实为试材,测定了不同北美海棠品种幼果果皮的颜色值、叶绿素、类胡萝卜素和花色素苷含量,并对以上果皮颜色指标进行聚类分类,并分析了幼果果皮颜色与叶色参数的相关性。聚类分析结果表明,可将供试的18个品种幼果果皮颜色分为绿色、暗红色或紫红色、红色、粉红色或玫红色、白粉色五类。结果表明:幼果期果实呈色受类胡萝卜素含量的影响不大,绿色果呈色主要受叶绿素含量较高的影响,果皮颜色随着花青苷含量的不断增加而逐渐变红,呈规律性变化,当花青苷达到一定量的时候,果皮呈现红色,如果同时受到其它色素的影响时,则呈现出不同色调的红色。花色素苷和叶绿素a的含量与果皮颜色密切相关,花色素苷的含量是影响果皮呈色的关键因素。In order to provide a reference for identifying varieties of Begonia in North American and for breeding and selection of fruit color, taking young fruits from 18 varieties of North American Begonia as materials, pericarp color values, chlorophyll contents, carotenoid contents, and anthocyanin contents in young fruits from different varieties of North American Begonia were determined. The varieties were clustered based on pericarp color index. And then relation of pericarp color of young fruit with parameters of leaf color was analyzed. The results of cluster analysis showed that pericarp color of young fruit of 18 varieties were clustered into five categories： green, dark red, red, pink, and white pink. The results showed that color of young fruits was not much affected by carotenoid content, and color of green fruit was mainly affected by chlorophyll contents. Pericarp color turned red gradually with anthocyanin content increased, and the change was regular. Pericarp color would be red when anthocyanin content reach a certain amount, and pericarp color would present different shades of red under other pigment affecting. Pericarp color was closely related to contents of anthocyanin and chlorophyll a, and anthocyanin content was the key infl uential factors on pericarp color.
