秦岭北麓大百合属野生植物资源的调查及应用研究

Investigation and Application of Wild Plant Resources of Cardiocrinum in Northern Foot of Qinling Mountains

为探究大百合属(Cardiocrinum)野生植物在秦岭北麓的存在及分布情况,项目组用5 a多的时间,对秦岭北麓24条峪进行了多季节、多次的实地考察,初步探明2种大百合属野生植物在秦岭北麓有居群分布,它们分别是云南大百合(Cardiocrinum giganteum var.Yunnanense(Elwes)Steara)和荞麦叶大百合(Cardiocrinum cathayanum.),其中荞麦叶大百合为首次在秦岭地区被发现,且仅在西安市鄠邑区的太平峪有分布,而云南大百合在秦岭北麓大多峪口有分布。文章对2种大百合的形态特征及应用前景进行了较为详细地描述及探索,以期为大百合属野生植物资源的后续研究提供参考。

This study aimed to investigate the existence and distribution of wild Cardiocrinum plants in the northern foot of the Qinling Mountains.Over a period of five years,we conducted multiple field visits in 24 valleys in the area. We found that two wild Cardiocrinum giganteum plants population distributed in the northern foothills of the Qinling Mountains, including Cardiocrinum giganteum var. Yunnanense ( Elwes ) Steara and Cardiocrinum cathayanum.Cardiocrinum cathayanum was first discovered in the Qinling Mountains, and it was only distributed in Taipingyu, Huyi District of Xi'an, while Cardiocrinum giganteum var. Yunnanense (Elwes) Steara was distributed in most of the valleys at the northern foot of the Qinling Mountains. In this paper, we described the detailed morphological characteristics and application prospects of two species of Cardiocrinum giganteum. This findings provide a reference for the follow-up study of wild plant resources of Cardiocrinum.
