| 摘要: |
| 龙脑香科植物广泛分布于热带亚洲,被认为是亚洲热带雨林的标志性物种。中国科学院西双版纳热带植物园从建园开始就注重龙脑香科植物的研究、收集与保护,并建立了龙脑香科植物专类园。经过几十年收集,现已成为我国龙脑香科植物重要的保育基地。该文结合历年的引种保育、物候及生长量观测等资料,系统整理了版纳植物园在龙脑香科植物引种保育和研究利用的工作。结果表明:自建园以来,版纳植物园共收集了7属34种龙脑香科植物,国内的有11种,国外的有28种。国内引种种类长势良好,除广西青梅外均能开花结果。国外种类开花结果的有13种。此外,版纳植物园部分龙脑香科植物种子生物学特性、植株抗寒及抗病虫能力的分析,也说明版纳植物园的龙脑香科植物的迁地保护是成功的。该文还结合新的研究成果,对龙脑香科植物在造林、生态恢复等方面的应用进行了探讨,以期为进一步加强该科植物的引种、保育及研发等工作提供参考。 |

| Abstract: |
| 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 |
