| 摘 要： | 为深入了解湖南地区紫薇种质资源的现状,在野外实地调查和馆藏标本、文献资料的收集、分析的基础上,对湖南省紫薇种质资源进行了系统研究。结果表明:湖南省共有紫薇、南紫薇、福建紫薇、尾叶紫薇、川黔紫薇、绒毛紫薇等6个紫薇种和111个紫薇品种,其中堇薇品种群36个、红薇品种群30个、银薇品种群14个、复色品种群23个、矮生品种群8个。在花色上,紫薇品种以红色和蓝紫色最多,分别为36和37个,而白色和复色较少,分别为14和24个;在品种演化上,紫薇花色的演化以蓝紫色和红色为基本原色,然后过渡到白色、复色,而株型演化则从乔灌木到矮生灌木。总体特征表现为株型单一,直枝型较多,垂枝型稀少;全部为落叶乔灌木,常绿紫薇尚无;彩叶稀少,尤其缺乏红叶和花叶性状;花色单调,多为紫色、红色,缺少大花、多花和香花品种。紫薇具有较高的观赏价值、营养价值、药用价值和生态价值,综合效益显著,有极大的发展潜力和广阔的市场前景。

| Abstract: | In order to obtain further knowledge about the status of Lagerstroemia indica germplasm resources in Hunan Province, this study made a systematic appraisal of L. indica germplasm resources based on field investigation and collections and on analysis of herbarium specimens and published literature. Six kinds of L. indica species were identified including L. indica, L. subcostata, L. limii, L. caudata, L. excelsa and L. tomentosa, and 111 varieties including 36 L. indica Amabilis Group, 30 L. indica Rubra Group, 14 L. indica Alba Group, 23 L. indica Bicolor Group and 8 L. indica Dwarf Group. Red and blue are the most common colors of L. indica with , 36 and 37 varieties respectively. There are also 14 white varieties and 24 combined colour varieties. With respect to evolution of plant characters blue-violet or red is the primitive color of L. indicawith transition to white and combined color, while the evolution of plant type is from arbor and shrub to dwarf shrub. The general characteristics are single plant type, many straight branches and a few hanger branches. All are deciduous shrubs, and there is no evergreen L. indica. Few colorful leaves, especially red leaf and floral leaf character. The color is humdrum, purple and red take the most part. It lacks of the variety with many big flowers which are fragrant flowers. L. indica has high ornamental value, nutritional value, medicinal value and ecological value, comprehensive benefits, which has great potential and broad market prospect. |
