摘要：通过广泛收集产自甘肃省渭源县、漳县、岷县、宕昌县、陇西县等地党参种苗30份,测定其根长、根粗、单根重,然后K聚类分析,依据聚类结果将种苗划分为3个等级,以不同等级为处理进行田间试验,研究不同等级党参种苗与药材产量及质量的关系,为制定党参种苗质量标准提供依据。研究结果显示,一级苗出苗最快,产量最高,且显著的高于二级苗和三级苗(P<0.05);一级苗炔苷含量最高,显著高于三级苗(P<0.05);三级苗多糖含量最高,显著高于二级苗和一级苗(P<0.05)。因此从党参药材产量、质量及投入成本综合分析,党参移栽应选择根长>15.6 cm,根粗>2.7 mm,单根重>0.56 g的种苗为宜。
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 3was 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.
