中文摘要: 中国是无心菜属(Arenaria)多样化及分化中心。具有无心菜属从原始、中间类型,到进化类型的多种代表类群,拥有较完整的进化序列。且具有非常高的特有性,中国是解决无心菜属乃至石竹科系统分类的关键地区。然而由于缺乏全面系统的分类学研究,导致属内各亚属间界限不明了,亚属内分类存在混乱。本研究利用馆藏标本,结合野外考察开展无心菜属的形态学研究,同时,参考国内外最新的研究成果,开展孢粉学和细胞学研究,以期为分类学修订提供有价值的参考。全面系统对国产无心菜属进行分类学研究,填补中国产无心菜属分类学研究空白;对世界无心菜属乃至石竹科分类学研究和无心菜属的系统演化有重要意义。

英文摘要: China is the diversity and differentiation center for Arenaria, with high endemic species, which shield the various representative groups from primitive, intermediate, and evolution taxa, owned the complete evolution sequence. It is the key to solve the problem of origin and evolution in Arenaria, and even the Caryophyllaceae. However, without a comprehensive taxonomic research, lead to chaos both in inter-genus and intra-subgenus in the genus. This research use herbaria material, combining with the field investigation, at the same time reference domestic and overseas the latest research results, carrying on palynology and cytological study, expected to offer valuable data for taxonomic revisions work. A comprehensive taxonomic research on domestic Arenaria, fill the blank of the taxonomic study in China; meanwhile the finding has important implications for the phylogeny of global Arenaria and than Caryophyllaceae.
