The study is aimed to research the relationship between the seedling grade of Codonopsis pilosula and yield and quality of medicinal materials, so as to provide basis for establishing seedling standard. Thirty seedlings of C. pilosula were collected from the main production areas in Gansu province, such as Weiyuan, Minxian, Zhangxian, Dangchang and Longxi, root length and diameter and weight of all the samples were measured. According to the clustering results, seedlings were divided into 3 levels, and field experiments were conducted with three levels seedling, yield and quality were tested in laboratory. Results have showed that emergence of grades 1 was faster than that of grades 2 and 3. Yield of grades 1 was significantly higher than that of grades 2 and 3 (P<0.05). Propargyl glycoside content of grades 1 was the highest, and significantly higher than that of grades 3. Polysaccharide content of grades 3 was the highest and significantly higher than that of grades 1 and 2 (P<0.05). So considering yield, quality and investment cost of C. pilosula, planting seedlings of C. pilosula should select that root length>15.6 cm, root diameter>2.7 mm, root weight>0.56 g.
本研究旨在探讨党参幼苗等级与药材产量和质量之间的关系，为制定党参幼苗标准提供依据。从甘肃省渭源、岷县、漳县、宕昌和陇西等主要产区采集30株党参幼苗，测量所有样本的根长、根直径和根重。根据聚类结果，将幼苗分为3个等级，并对3个等级的幼苗进行田间试验，在实验室测定产量和质量。结果表明，1级幼苗的出苗速度比2级和3级快。1级幼苗的产量显著高于2级和3级（P<0.05）。1级幼苗的炔苷含量最高，且显著高于3级。3级幼苗的多糖含量最高，且显著高于1级和2级（P<0.05）。因此，综合考虑党参的产量、质量和投资成本，种植党参幼苗应选择根长>15.6 cm、根直径>2.7 mm、根重>0.56 g的幼苗。
