兰科地宝兰属植物研究进展

Advances in Studies of Geodorum G.Jacks.(Orchidaceae)

地宝兰属(Geodorum G.Jacks.)植物隶属于兰科(Orchidaceae)兰亚科(Subfam.Orchidoideae)树兰族(Trib.Epidendreae)美冠兰亚族(Subtrib.Eulophiinae)地生兰类群,全属约10种,分布于亚洲热带地区、澳大利亚和太平洋岛屿。我国地宝兰属植物有5种,在广东、海南、广西、贵州、台湾、四川和云南等地有分布记录。本文结合近几十年来地宝兰属植物的研究动态,阐述该属植物的资源概况、濒危原因、保护现状、细胞学、繁殖技术、菌根真菌、传粉生物学及遗传多样性等方面的研究进展,并提出下一步研究建议,以期为制定地宝兰属植物的保护策略和实施相关研究工作提供参考。

Geodorum G.Jacks.is an orchid genus belonging to Cymbidieae of Orchidaceae,with about 10 species in the world,which distributes in tropical Asia,Australia and Pacific islands.In China,there are 5 species,which are recorded in Guangdong,Hainan,Guangxi,Guizhou,Taiwan,Sichuan and Yunnan.In this paper,the research trends of Geodorum G.Jacks.plants in recent decades were reviewed,the research progress on the resources,endangered reasons,protection status,cytology,reproductive technology,mycorrhizal fungi,pollination biology and genetic diversity of the genus Geodorum G.Jacks.were described,and suggestions for further research were put forward to provide reference for the formulation of protection strategies and implementation of related research work of Geodorum G.Jacks..
