摘要： 旨在建立北沙参种子的质量分级标准。通过观察种子的外部形态，测定其净度、饱满度、含水量、千粒重、发芽率及生活力等各项指标，制定北沙参种子的质量分级标准。结果表明：不同处理的北沙参种子质量均分成3个等级：沙藏前的一级、二级和三级种子的净度分别≥95.0%，90.0%，85.0%；饱满度分别≥70.0%，60.0%，50.0%；含水量分别为8.0%~12.0%，8.0%~12.0%，≥12.0%或≤8.0%；千粒重分别≥23.00g，18.00g，15.00g；发芽率分别≥12.0%，10.0%，8.0%；生活力分别≥35.0%，25%，15%。沙藏后的一级、二级和三级种子的发芽率分别≥65.0%，60.0%， 55.0%；生活力分别≥70.0%，65.0%，60.0%，其余指标均与沙藏前的北沙参种子分级标准一致。本研究初步制定了北沙参种子的质量分级标准，可为其在生产和销售过程中的质量评价以及对北沙参药材进行质量标准的建立提供参考。

Abstract: In order to establish the quality grading standard of the seeds of Glehnia littoralis. By observing the external morphology of the seeds and measuring its indicators of purity, plumpness, water content, 1000-grain weight, germination rate and viability, the quality grading standard of the seeds of Glehnia littoralis was established. The results show that: The seed quality of different treatments was divided into three grades: the purity of the first, second and third grade seeds before sand storage was ≥95.0%, 90.0%, 85.0%, respectively; the plumpness was ≥70.0%, 60.0%, 50.0%, respectively; the water content was 8.0%~12.0%, 8.0%~12.0%, ≥12.0% or ≤8.0%, respectively; 1000-grain weight was ≥23.00g, 18.00g, 15.00g, respectively; germination rate was ≥12.0%, 10.0%, 8.0%, respectively; viability was ≥35.0%, 25%, 15%, respectively. The germination rate of the first, second and third grade seeds after sand storage was ≥65.0%, 60.0%, 55.0%, respectively; viability was ≥70.0%, 65.0%, 60.0%, respectively, and the other indicators are consistent with the grading standard of seed before sand storage. In this paper, the quality grading standard of the seeds of Glehnia littoralis has been preliminarily established, which can provide reference for the quality evaluation in the process of production and marketing and the establishment of the quality standard for Glehniae Radix.
