摘要: 本文对12种固沙常见锦鸡儿属植物的分类、分布、花粉形态进行了比较研究。确定了柠条锦鸡儿、中间锦鸡儿和小叶锦鸡儿三者的亲缘关系,并认为绢毛锦鸡儿是这12种中最原始种,锦鸡儿属可能正象Komapob所说的,是由一个比较原始的祖先种沿着不同的途径衍化而形成目前的许多种。

关键词: 锦鸡儿属, 分布, 分类, 花粉形态

Abstract: In this paper 12 common fixators of genus Caragana Fabr.have been studied comparatively.The study includes their distribution,habitats,and pollen morphology.Study confirmed the sibshisp of three species,D.intermedia Duanget H.C.Fu,C.microphylla Lam.and C.korshinskii Kom.C.hololeuca Bge.ex Kom.is the most original species,while the Caragana Fabr.,as Komarov had said,evolved from one original species.So the study of pollen morphology and distribution of this genus will contribute to sotve such prlblems,as the phylogeny and the centres of origination of the genus.
