摘　　要：爪耳木作为国家二级保护珍稀濒危物种,为我国特有植物,目前在IUCN上仍被列为灭绝级(EX)植物。爪耳木在2013年被科研人员再次发现后,科研人员围绕爪耳木的资源调查以及生物学特性、种苗繁育等方面开展了相关研究。爪耳木目前作为一种在野外已灭绝的植物,对其开展相关研究和重新回归野外具有重要价值,对爪耳木属植物系统发育和进化的研究也有重要参考价值。文章对爪耳木开展繁育经验总结发现,爪耳木可以通过种子繁殖、叶和根扦插、根蘖繁殖获得新植株。爪耳木的成功大量繁育将为爪耳木后期的野外回归做好准备,并有助于其野外种群的恢复和保护以及濒危机制探讨等一系列研究的深入开展。Lepisanthes unilocularis,a rare and endangered species protected at the national level with second class,is the Chinese endemic plant.It is still listed as an extinct plant by the International Union for Conservation of Nature.Lepisanthes unilocularis was rediscovered by researchers in 2013.Researchers have carried out relevant research on resource investigations,biological characteristics,seedling propagation,etc.Lepisanthes unilocularis is now an extinct plant in nature.It is of great value to carry out relevant research and reintroduction into the wild.It also has vital reference value for the study of the phylogeny and evolution of Lepisanthes.In this paper,the propagation experience summary of Lepisanthes unilocularis was discussed.The results revealed that new plants could be obtained via seed propagation,leaf and root cuttings,and root sprout propagation.Successful mass propagation will prepare for the later reintroduction of Lepisanthes unilocularis.And facilitate the in-depth development of a series of related studies,including the restoration and protection of the wild population and the mechanism of its endangerment.
