版纳植物园龙脑香科植物迁地保护成效与应用探讨.

Dipterocarpaceae plants are typical lowland tropical trees, and are usually regarded as the flagship species of Asia tropical rainforest. Xishuangbanna Tropical Botanical Garden(XTBG)is one most important botanical garden focus on tropical plant collection, conservation and research since 1959. This paper reviews Dipterocarpaceae collection history, research and utilization of at XTBG based on the phenological observation, mass growth, and adaptability. The results showed that 34 species of Dipterocarpaceae from 7 genera had been collected in the garden, among which 11 species from China and 28 species abroad. All the species have flowers and fruit collected from China, except for Vatica guangxiensis. There are 13 species that have flowers and fruits collected from overseas. Integrated with seed germination traits, cold and disease resistance data, we concluded that XTBG Dipterocarpaceae plants ex-situ conservation is successful, which may afford a better guide for Dipterocarpaceae plants conservation in the future.
