不同产地蒙古黄芪种子质量研究

Study on seed quality of Astragalus mongholicus Bunge from different areas

目的：通过研究9个不同产地蒙古黄芪种子的质量,筛选优质黄芪种子,为黄芪规范化种植提供参考。方法：对9份不同产地蒙古黄芪种子进行质量检测,包括净度分析、水分、发芽率的测定。结果：所收集的9份种子杂质较少,平均净度均可达到90%以上;以甘肃岷县的黄芪种子含水量最高,为10.54%,甘肃张掖的种子水分含量最低;包头市固阳县和渭源县会川镇两个产地的种子硬实程度较低,自然发芽率可达65.3%以上。结论：用98%浓硫酸处理可明显提高黄芪种子发芽率,种子质量的差异受多种因素影响。

Objective：To study the seed quality of Astragalus mongholicus Bunge from 9 different habitats and select the seed of Astragalus membranaceus with high quality,so as to provide reference for the standardized cultivation of Astragalus membranaceus. Methods：The quality of Astragalus mongholicus Bunge seeds in 9 different habitats was tested,including clarity analysis, water content, the germination rate and viability measurement. Results： The seeds were less and the average clarity could reach more than 90%. The water content of Astragalus membranaceus seeds was the highest at10.54% in Minxian County of Gansu Province; the hardness of seed in Guyang County of Baotou City and Weiyuan County was low with a natural germination rate of more than 65.3%. The seed quality of Astragalus mongholicus Bunge in Longxi of Gansu and Chifeng City of Inner Mongolia was relatively poor. Conclusion：The treatment of 98% concentrated sulfuric acid can obviously improve the germination rate of Astragalus seeds. The quality of Astragalus membranaceus seed is affected by many factors.
