目的:比较秦艽栽培品种与野生品种的性状差异,对主要品质性状进行相关性分析,并对不同产地栽培秦艽的品质性状进行筛选。方法:应用SPSS统计软件对123份秦艽主根长度、支根数、主根直径、残留茎数、干重等性状进行分析和评价。结果:秦艽栽培品的主要品质性状均高于野生品,显著性差异排序为:支根数〉干重〉主根长度〉主根直径〉残留茎数;主要品质性状间呈现极显著正相关;栽培秦艽综合品质性状以陕西省凤县南星镇留凤关村玉林蒲的最优。结论:秦艽的栽培品相对于野生品粗大,根下部分枝较多;表面及断面颜色较浅等。本研究结果为药典秦艽性状修订,秦艽优良种质筛选、引种、推广以及资源的合理利用提供参考。
Objective: To investigate the difference of macroscopic characteristics between cultivated Gentiana macrophylla and wild one,analyze the correlation among its main quality traits and preliminary screen cultivated Gentiana macrophylla from different habitats based on quality traits.Methods:Measured and obtained characteristic index,including main root length,lateral root number,taproot diameter,residue stem number and dry weight,and analyzed data by SPSS 12.0 statistical software.Results:The main characteristics of cultivated Gentiana macrophylla were all better than those of the wild one.The characteristics was sequenced as follows:lateral root number dry weight main root lengthy taproot diameter residue stem number in order of difference.There were remarkable positive correlations among main quality traits.The optimal germplasm was located in Yulinpu of Liufengguan Village,Nanxing Town,Feng County in Shaanxi Province.Conclusion:Cultivated Gentiana macrophylla is relatively robust,having more branching roots with light colour of surface and section compared with the wild one.The paper provides suggestions for the revising of macroscopic characteristics of Gentiana macrophylla in the next edition of pharmacopoeia;The data offer scientific reference for screening excellent germplasm,introduction expansion and reasonable utilization of resources as well.
