    摘要:

    悬钩子属植物具有很高的经济价值,目前认为中国西南地区是悬钩子属植物的分布中心;然而,尚不清楚该区域悬钩子属野生植物资源的本底。本研究通过野外考察、查阅标本和文献的方法,对中国西南的悬钩子属植物资源进行调查,同时对西南地区悬钩子属植物资源的收集、保存及有药用价值的植物进行初步探讨。结果发现:中国西南地区有悬钩子属植物142种、69变种,其中特有种47种、40变种;据报道有药用价值的有22种、1变种;适合在滇西北高海拔地区作为育种材料或引种驯化的有5种;这些悬钩子属植物资源分布在海拔300-4300 m。本文较为系统的介绍了其分布区、海拔、生活型、生境类型以及植物学特性和遗传多样性,为悬钩子属植物资源的开发和遗传育种提供了基础数据。

    Abstract:

    The genus Rubus have significant economic value, with southwest China considered as a key distribution center for these species. However, the status of wild Rubus resources in this region remains largely unexplored. In this study, the Rubus resources in southwest China were investigated by field studies, specimen examination and literature review. Additionally, the study preliminarily addressed the collection, preservation and medicinal potential of Rubus resources in southwest China. The results showed that there were 142 Rubus species and 69 varieties in southwest China, among which 47 species were endemic and 40 varieties. There were 22 species and one variety with medicinal value, while five species are suitable for use as breeding materials or for introduction and domestication in the high altitude area of northwest Yunnan. These Rubus resources are found across a wide range of altitudes, from 300 to 4300 m.This study systematically presented the distribution, life type, habitat type, botanical characteristics and genetic diversity of Rubus species, which provided foundational data for the future development and genetic breeding of Rubus resources.
