摘要
对广西热带稀有濒危植物在广西及邻近省份植物园的引种保育进行对比研究。结果表明:大部分树种在热带和南亚热带可以正常生长,通过适当的保护措施,部分树种在中亚热带的桂林可以保存。低温和霜冻是广西热带稀有濒危树种能否成功保存的主要限制因素,因此,在引种保存过程中要注意防寒和树种的选择,以提高迁地保护的有效性。
The paper compares the introduction and preservation of tropical rare and endangered plants of Guangxi and the botanical gardens in adjacent provinces. The results show that most of them can grow well in tropics and southern subtropics under properly protective measures,part of them can be conservated in middle subtropics Guilin. The low temperature and frost are key factors of the survival of tropical rare and endangered plants in Guangxi. Therefore,more attentions must be paid for cold preventing and the choice of plants, in order to raise the efficiency of ex-situ conservation.
