摘要:

我国兜兰属种质资源丰富，已知拥有34种原产种，其中云南和广西等西南部地区是我国的主要分布区域。 除带叶兜兰Paphiopedilum hirsutissimum和硬叶兜兰P. micranthum被列为国家二级重点保护植物外，其它兜兰属植物均被列为国家一级重点保护野生植物。兜兰属植物一直受到许多学者的广泛关注，本文综述了近十几年来兜兰属植物在生理生态特性和保护遗传学方面研究进展，指出当前研究中的不足和问题并提出合理的建议与展望，以期为兜兰属植物保护策略的制定和未来相关研究提供科学的参考依据。

Abstract:

Paphiopedilum has rich germplasm resources in China, and 34 Paphiopedilum species are known to be native to China. The southwestern regions such as Yunnan and Guangxi are the main distribution areas in China. It should be noted that Paphiopedilum hirsutissimum and P. micranthum are listed as national second-class key protected plants, while other Paphiopedilum species are classified under the category of national first-class key protected wild plants. The subject of Paphiopedilum plants has been a significant area of interest for many scholars. Therefore, in order to provide a scientific reference for the formulation of Paphiopedilum plant protection strategies and the development of related research in the future, this paper comprehensively explains the research progress and results of Paphiopedilum plants in physiological ecology and conservation genetics such as photosynthetic traits in the past ten years, finds out the shortcomings and problems in the current research, and puts forward reasonable suggestions and prospects.
