经１４ａ的收集和引种栽培，已引进了我国热带、南亚热带地区的珍稀濒危树种共３８科６３属８３种，占全国保护树种总数的２３．４％，占广西保护树种总数的６７．４％。对３０个保护树种进行了播种、扦插等试验，已成功地繁殖了一批苗木。进行了３４个树种的物候相、生长量、适应性等观测。并建立了０．４６ｈｍ２的种质资源引种保存区

A Study On the Introduction of Rare Endangered Tree Species in Tropics and southern Subtropics

After 14- year's collection and culture of introduced species,some 83 rare en-dangered species of 63 genera and 38 families in China's tropics and southern subtropics havebeen introduced ,accounting for 23.4% of China's protected species and 67.4%of those inGuangxi Province. Experiments of sowing and cutting etc. on 30 protected species have beenconducted,and large numbers of seedlings have been successfully propagated. Observationson phenology phase,growth increment and adaptability etc.on 34 species have been carriedout. Besides,46 hm2 introduction- reserve of germ-plasm resource has been set up.
