摘　　要：在吉林省10个北细辛人工栽培地,采集了2年生和3年生北细辛种苗样本各10份,共计5900株,分别对毎株样本的须根长、须根粗、须根数、单根重等4个质量指标进行了测定,对测定数据进行差异性分析以及相关性分析,并结合生产实际,采用次数分布频率法,将2年生和3年生北细辛种苗分别分为3个等级,并初步制定了北细辛种苗分级标准,为北细辛种苗质量评价及该药材规范化生产提供了参考依据。Abstract. We collected Artificial cultivation ofAsarum heterotropoides Fr.Schmidt var.Mandshuricum seedlings that from Jilin province asarum region as sample, including 2 years A.heterotropoides Fr.Schmidt var.Mandshuricum seedlings, 10 copies of resources and 3 years .4.heterotropoides Fr.Schmidt var.Mandshuricum seedlings, 10 copies of resources.We investigates the main quality index（fibrous root length, fibrous root thick, fibrous root number and root weight）as the feasibility of seedling grading traits.Based on the difference analysis and correlation analysis, and combining the production practice, The seedlings quality grading of biennials A.heterotropoides Fr.Schmidt var.Mandshuricum seedlings and triennialA.heterotropoides Fr.Schmidt var.Mandshuricum seedlings was set as three grades by using the frequency distribution method.The quality classification criteria ofA.heterotropoides Fr.Schmidt var.Mandshuricum seedlings have been initially established.This paper provides a reference for the quality evaluation ofA.heterotropoides Fr.Schmidt var.Mandshuricum seed- lings and the normalization production ofA.heterotropoides Fr.Schmidt var.Mandshuricum.
