| 中文摘要: |
| 檀香紫檀是名贵的红木树种，极具历史文化价值与实用价值，国内市场需求高涨，但长期以来
缺乏切实可行的高效繁育技术，产业发展难以为继。从荚果播前机械处理和酸处理两个方面进行研究，探
讨了不同程度机械处理对当年、次年播种荚果发芽率的影响，并使用浓硫酸浸种不同时间，以期找到快速
便捷的檀香紫檀荚果播前处理方法。结果表明，檀香紫檀荚果以随采随播为佳，经过1 年贮藏后种子活力
降低、发芽困难；剪除果翅（至可见种子）即可提高当年播种荚果发芽率至73%，提高次年播种荚果发芽
率至58%；浓硫酸浸种效果未达到预期，浸泡时间以10 min 以内为佳，可提高发芽率至37%，但导致幼苗
叶片可溶性蛋白含量显著升高。 |
| 英文摘要: |
| Pterocarpus santalinus is a rare species of rosewood with great historical and cultural value and
practical value. But for a long time，the development of P. santalinus industry is difficult to sustain because of the
rising domestic market demand and the lack of practical and efficient breeding technology. In this paper，different
mechanical treatments and acid treatments before pod sowing were studied to explore the effects of different degree
of mechanical treatments on the germination rate in current year and next year，and to find a quick and convenient
pod pre-sowing method of P. santalinus through the innovative use of concentrated sulfuric acid for seed soaking with
10 min，20 min，30 min or 40 min. The results showed that P. santalinus pods had better seed vigor with mining
sowing，and after one year of storage，the seed vigor decreased and it was difficult to germinate. Cutting fruit wings
to visible seeds could increase seed germination rate to 73% for sowing in current year and 58% in the next year. The effect of concentrated sulfuric acid for seed soaking did not reach the expectation. And the effect of seed soaking was
better within 10 min，the germination rate could increase to 37%，but the soluble protein content of seedling leaves
increased significantly. |
