Ex Situ Conservation and Landscape Application of Rare and Endangered Plants-A Case of Nanning Botanical Garden
摘要
Abstract
In order to strengthen the ex situ conservation and application of rare and endangered plants in Nanning Botanical Garden,through field investigation and data collection,the species,composition and diver-sity of rare and endangered plants in Nanning Botanical Garden were analyzed and evaluated,and the possibil-ity of garden application was explored.The results showed that:(1)there were 234 species of rare and endan-gered vascular plants belonging to 66 genera and 37 families in Nanning Botanical Garden,all of which were national key protected wild plants.Among them,134 species of 17 genera in 5 families belonged to the Con-vention on International Trade in Endangered Species of Wild Fauna and Flora(CITES).210 species be-longing to 62 genera and 33 families were listed in the IUCN Red List of Threatened Species.There were 10 families,13 genera and 32 species belonging to extremely small populations.There was one species belonging to the key protected plants in Guangxi Zhuang Autonomous Region.(2)Landscape application could be di-vided into three types:growth type(evergreen trees,deciduous trees,evergreen shrubs,perennial herbs),or-namental type(flower,leaf,shape,fruit,stem and aromatic plants)and ecological type(sun,neutral,shade tolerant).(3)Orchidaceae,Cycadaceae and Theaceae had the highest proportion of species,with 126,22 and 12 species,respectively.(4)The flowering period of rare and endangered plants in Nanning Botanical Garden was concentrated from April to August,and the fruit period was concentrated from September to November,which could be well applied to the landscape.In general,the ex situ conservation of plants in Nanning Botani-cal Garden was biased to gymnosperms and threatened plant species.At present,the prominent problem is that the number of rare and endangered plants is still small,and the collection of regional national key protec-tion wild plant germplasm resources is not comprehensive,so the species diversity still needs to be improved.Good adaptability and common species reach 95.30%,which can be further combined with the advantages to make more fine management in the garden application.This study provids a scientific basis and reference for the ex situ protection,later return and garden application of rare and endangered plants in Nanning Botanical Garden.关键词
