摘要:

本研究通过对红雪茶基源种进行考证,并结合品种鉴定及野外生态调查,结果表明,红雪茶的基源种应为金丝刷(Lethariella cladonioides)和金丝带(L.zahlbruckneri),在这两个种群内,存在化学多态现象。市售的“红雪茶”主要由这两个种的四个化学宗所组成。红雪茶的分布中心主要在藏东南,滇西北及川西地区,目前红雪茶的资源已经受到了极大的破坏,日渐濒危。为加强对野生红雪茶资源的有效保护,提出了开展红雪茶种质资源保护的建议。

关键词: 红雪茶, 基源种, 濒危物种

Abstract:

The textual criticism of original species of Hongxuecha has been made combining species identification and field surveys. The results showed that Hongxuecha had two original species, Lethariella cladonioides and L.zahlbruckneri. There were chemical variability within the two populations. Hongxuecha in the market sales included four chemical races of the two species. The distribution center of Hongxuecha was mainly in the southeastern Tibet, western Sichuan and northwestern Yunnan. Currently, Hongxuecha resources have been greatly damaged and species are facing extinction. To enhance effective protection for wild hongxuecha resources, some proposals were presented.

Key words:  Hongxuecha, Original species, Endangered species
