| 摘要: |
| 兰科杓兰属（Cypripedium）植物主要分布于东亚、北美等温带地区和亚热带山地。杓兰不仅具有极高的观赏价值，而且其经济价值和科研价值也越来越受到人们的重视。近年来对杓兰属植物人工繁殖的相关研究不断深入，主要集中于种子的非共生萌发等方面。本文对濒危兰科杓兰属植物进行了简要介绍，并就其种子非共生萌发研究从种子成熟度、预处理和有机添加物的作用、培养基的配置等方面进行综述，为目标杓兰种类的非共生萌发试验方案的制定奠定基础，将有助于温带/高山兰科植物保育研究的发展。 |

| Abstract: |
| Cypripedium plants are mainly distributed in temperate Asia and North America. They not only have very high ornamental value, but also their economic value and scientific research value are more and more concerned by people. In recent years, researches on propagation of Cypripedium have been deepened, mainly focus on asymbiotic germination of the seeds. This paper briefly introduces the endangered orchids of Cypripedium, and summarizes the research progress of seed asymbiotic germination from aspects of seed maturity, pretreatment, the role of organic additives, and the configuration of media. The study lays the foundation for the asymbiotic germination experiment program of the orchid species, and promotes the research and development of orchid plant conservation. |
