摘　　要： 2002年从泰国和越南引进缠结龙脑香、蛇羯布罗香、小瘤龙脑香、具翼龙脑香、钝叶娑罗双、泰国娑罗双和香坡垒等7种龙脑香科树种,对种子的采集、处理、运输、播种育苗等开展了系列研究。结果表明:不同的树种种子保存条件和时间差别很大,发芽率差异明显,最高的发芽率可达100%,最低的为27%;在广州地区,苗木能在自然条件下正常生长发育,且生长较快,生长量普遍超过用作对照的乡土阔叶树种木荷和香樟,且苗木健壮、生机旺盛,特别能忍受干旱的环境和气候条件,具有良好的开发利用前景。 The study are focused on the seed collection, processing, dispatching, sowing and cultivation of the introduced Dipterocarps from Thailand and Vietnam including D.intricatus, D.obtusifolius, D.tuberculatus, D.alatus, Shorea obtuse, Shorea siamensis and Hopea odorata . The results showed that there were large varience on storage duration, storage requirements and germination rate among the species, with highest germination rate of 100% while the lowest of 27%. In Guangzhou, all the species gorw naturally. The growth performance on seedling stage was better than indigenous broadleaved species such as Schima superba and Cinnamomum camphora, with healthy and vigorous seedling, good resistance to drought site conditions. They are a great promising potential on the application future.
