【摘要】 目的:研究当归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:广泛收集产自甘肃当归主产区岷县、漳县、宕昌、渭源的当归种苗30份,以单根重为指标对所有样品进行测定,并对测定结果进行聚类分析,依据聚类中心值将种苗划分为3个级别,以级别为处理进行田间试验,实验室检测药材质量。结果:二级种苗(单根重0.74～1.38 g)成药期植株的根干重、地上部干重、全株干重等生长指标均超过其他处理及对照;田间抽薹率低,药材单根重大,产量位居第一;所成药材的外部性状优,阿魏酸含量高于药典(2010年版一部)标准。结论:二级种苗的植株生长量大、产量高、质量优,可作为生产用种苗的首选。更多还原

【Abstract】 Objective:To research the relationship between the seedling grade of angelica and the biomass accumulation,output and quality of product,so as to provide base for establishing seedling standard.Method:Thirty seedlings of Angelica were collected from the main production area in Gansu province,such as Minxian,Zahngxian,Dangchang and Weiyuan county,all the samples were measured with weigh of single seedling and the seedling were divided into three grade by the clustering analysis results,the grade were made to treatment to do field test and laboratory experiment.Result:The weigh of dry root,above ground and the whole plant in growth period of treatment 2(the weigh of single seedling between 0.74-1.38 g) were all superior to other treatments and the ck.The treatment 2 had low bolting percentage,the weigh of single root was higher and the yield was the highest.The characters of product from the treatment 2 was well and the content of ferulic acid was higher than the standard of Chinese pharmacopoeia(2010 year part 1).Conclusion:The plant from the grade 2 seedling with larger growth increment,higher output and better quality,which can be the best seedling in production.更多还原
