【摘要】 对渥丹百合种内10个居群的茎、叶、花、果实、种子的25个性状进行了调查和分析,研究不同居群的形态多样性。结果表明:根据分类学性状可将渥丹分为变种有斑百合、黄花渥丹和大花百合。大花百合比有斑百合的叶宽且短,花瓣长且宽,花粉生活力低,种子有胚率低;黄花渥丹比有斑百合叶长且宽,花瓣长且宽,种子有胚率和发芽率低。有斑百合与黄花渥丹亲缘关系较近,与大花百合亲缘关系较远。更多还原

【Abstract】 More than 20 morphological traits of stems,leaves,flowers,fruits and seeds of Lilium concolor Salisb.had been measured and analyzed.10 populations of L.concolor Salisb.could be classified into three varities: L.concolor var.buschianum Baker.,L.concolor var.megalanthum Wang et Tang and L.concolor var.concolor f.coridion Kitag.in this paper.L.concolor var.megalanthum Wang et Tang had wider and shorter leaves,longer and wider petals,lower vitality of pollens and lower percent of seeds with embryo than L.concolor var.buschianum Baker.;L.concolor var.concolor f.coridion Kitag.had wider and longer leaves,longer and wider petals,lower percent of seeds with embryo and lower percent of germination than L.concolor var.buschianum Baker..There was closer relationship between L.concolor var.buschianum Baker.and L.concolor var.concolor f.coridion Kitag.,further relationship between L.concolor var.buschianum Baker.and L.concolor var.concolor f.coridion Kitag.更多还原
