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 compare the traits of cultivars and wild varieties of Gentiana macrophylla, analyze the correlation of main quality traits, and screen the quality traits of Gentiana macrophylla from different areas. Methods: SPSS statistical software was used to analyze and evaluate the length, branch number, diameter of main roots, residual stalks and dry weight of 123 main parts of Gentiana macrophylla. Results: The main quality traits of cultivars of Gentiana macrophylla were higher than those of wild ones. The order of significant difference was: number of stems> dry weight> length of main roots> diameter of main roots> number of residual stalks; there was a significant positive correlation between main quality traits; Comprehensive quality traits in Fengxian County, Shaanxi Province left Fengguan Village Yulin best. Conclusion: The cultivars of Gentiana macrophylla are larger than the wild ones, with more branches in the root and shallower color of the surface and section. The results of this study provide references for the revision of the characters of Gentiana macrophylla, the screening of fine quality of Gentiana macrophylla, introduction, promotion and rational utilization of resources.
