Collection and Utilization of Germplasm Resources of Myrtaceae Wild Plants in China

Myrtaceae is an important group of higher plants, the eighth family of angiosperms, with 134 genera, 5500-5900 species, mainly distributed in tropical America, Oceania and Asia. There are 9 genera, 126 species and 8 varieties of wild myrtle in China. South China Botanical Garden of Chinese Academy of Sciences introduced and related studies on the Myrtaceae wild plant germplasm resources since the 1930s. There are 58 species of 9 genera of Myrtaceae wild plants in China, of which there are 1 species of the genus Acmena, 1 species of the genus Baeckea, 2 species of the genus Cleistocalyx, 3 Species of the genus Decaspermum, 2 species of the genus Psidium, 2 species of the genus Pyrenocarp, 1 species of the genus Rhodamnia, 1 species of the genus Rhodomyrtus, and 45 Species of the genus Syzygium were collected. Myrtle plants have an important and far-reaching impact on the world economy in wood resources, volatile aromatic oils, industrial and pharmaceutical materials, edible spices, tropical fruits, and ecological and environmental protection. This paper studies the collection and application of wild plant germplasm resources of myrtle in China, in order to provide strategic support for China's economic development, sustainable utilization of resources and ecological environment protection.
