目的:针对甘肃传统大宗药材黄芪种子在生产中发芽及育苗成功率低的突出问题,以打破黄芪种皮硬实性和改善其种子发芽情况为目标。方法:通过75%酒精、浓硫酸、温育、研磨处理及温育+轻度研磨+沙培集成处理等对供试陇西黄芪种子进行处理,并通过发芽势、发芽率及发芽指数等3个指标对不同处理方法进行评价。结果:不同处理方式对黄芪种子发芽均有显著提高,且不同处理方式对其种子发芽势、发芽率及发芽指数的影响存在较大差异;温育+轻度研磨+沙培集成处理后的供试黄芪种子发芽效果最好,其种子发芽势达66.04%、发芽率达87.70%、发芽指数达1.34,且均显著高于其他处理方法。结论:温育+轻度研磨+沙培集成处理是最经济有效的处理方法,可操作性相对较好,更接近生产实际。
OBJECTIVE: According to the prominent problems of germination and seedling success rate of Astragalus mongholicus, a traditional Chinese medicine, in Gansu province, the goal is to break the hard solidity and improve the seed germination of Astragalus. Methods: Astragalus membranaceus seeds from Longxi were treated with 75% alcohol, concentrated sulfuric acid, incubation, grinding and incubation + mild grinding + sand culture, and the germination potential, germination rate and germination index Indicators to evaluate different treatment methods. Results: The results showed that the different treatment methods significantly increased the germination of Astragalus membranaceus seeds, and the effects of different treatments on the germination potential, germination rate and germination index of the seeds were quite different. After incubation, Astragalus seed germination best, the seed germination potential reached 66.04%, germination rate of 87.70%, germination index of 1.34, and were significantly higher than other treatments. Conclusion: Incubation + mild grinding + sand culture integrated treatment is the most economical and effective treatment method, the operability is relatively good, closer to the actual production.
