百脉根(Lotus corniculatus L.)是豆科百脉根属的多年生草本植物。原产于欧洲及亚洲的温带地区。现分布于欧洲、北美、印度、澳大利亚及新西兰等地。在美国东北部及西海岸有大面积栽培。我国华南、西南、西北、华北、内蒙古等地均有分布。四川、云南、贵州、湖北等地有野生种,为进行野生牧草驯化工作提供了宝贵的资源。过去国内开展百脉根的种质研究多着重于引进品种,而对探讨和开发利用我国的野生种质资源却尚不多见。本文对川北剑阁地区的野生百脉根作了初步研究,以期能为驯化栽培利用提供一点参考资料。
Lotus corniculatus L. is a leguminous root perennial herb. Native to temperate regions of Europe and Asia. Now distributed in Europe, North America, India, Australia and New Zealand and other places. In the northeastern United States and the West Coast has a large area of cultivation. China’s southern China, southwest, northwest, north China, Inner Mongolia and other places are distributed. There are wild species in Sichuan, Yunnan, Guizhou and Hubei, which provide precious resources for domestication of wild forages. In the past, the research on germplasm development of Lotus japonicus in China focused more on the introduction of varieties, but it was still rare to explore and exploit the wild germplasm resources of our country. In this paper, a preliminary study on the wild Lotus japonicus in Jiange region of northern Sichuan was carried out in order to provide some reference materials for domesticated cultivation and utilization.
