摘要：目的:研究甘草种苗等级与植株生物量积累、药材产量和质量的关系,为制定种苗标准提供依据。方法:以单根重量为分级指标对甘草种苗进行分级,采用聚类分析方法将种苗聚类分级为3个级别,以级别为处理进行田间试验,连续两年于生长期测定甘草植株鲜重和根干重,实验室测定药材有效成分含量。结果:一级、二级种苗(单根重10.0 g以上)生长期植株的总生物量、根干物质量及产量均大于三级种苗。3年生药材的甘草酸、甘草苷、芹糖基甘草苷和甘草素的含量,一、二级种苗高于三级种苗;不同等级种苗药材甘草酸和甘草苷的含量均高于2010年版中国药典一部标准。结论:种苗等级对甘草药材的质量及产量均有影响,生产上建议选用单根重在10.0g以上的种苗。
Objective：To research the relationship between the seedling grade of Glycyrrhiza uralensis and the biomass accumula- tion, yield and quality of product, so as to provide basis for establishing seedling standard. Methods：The weight of single seedling root was measured and the seedlings were divided into three grades by the clustering analysis. The different grade treatments of seedlings were made to conduct field trials and laboratory experiments. Results ： The weight of the whole plant and dry rout in growth period of grades 1 and 2 （the weight of single root greater than 10. 0 g）were larger than grade 3, and the yield was also the case. The root of Gly- cyrrhiza uralensis, growing for three years, of grades 1 and 2 contained higher contents of active compounds than grade 3, and the content of glycyrrhizin and liquiritin in the root of Glycyrrhiza uralensis of all treatments were higher than the standard of Chinese Pharmacopoeia （2010 edition）. Conclusion：The plant from the grades 1 and 2 seedlings with larger growth increment, higher output and better quality is the best seedling in cultivation.
