| 摘要: |
| 交趾油楠是东南亚热带重要的优势珍贵用材树种，本文对交趾油楠的分布、用途、种子特性进行了简要介绍，在引进交趾油楠种子资源的基础上，针对其种皮硬实导致发芽困难的问题，开展了播种催芽处理试验，结果表明，人工破皮或者60～70℃温水浸泡可以加速交趾油楠种子发芽时间，显著提高交趾油楠种子的发芽率，发芽整齐一致。文章对播种方法及其注意事项、苗期管理和造林保存初期表现以及发展前景进行了论述，以促进交趾油楠在我国的研究和发展。 |

| Abstract: |
| Sindora cochinchinensis is an important tropical tree speices of valuable wood in Southeast Asia. It’s distirbution, function, seed characteristics were briefly introduced in this paper. The accelerating germination trial was carried out in order to solve the problem of difficult in seed germination due to it’s hard seed coat. The results showed that artificial rupture on seed or soaked in 60～70℃ warm water can effectively accelerate germination and improve germination rate of Sindora cochinchinensis seeds. The sowing methods and notes, seedling managements, early performances of family test plantations and development prospect were also discussed. |
| Key words: Sindora cochinchinensis, hard seed, accelerating germination treatment, seedling cultural technique, introduction and conservation |
