目的为了筛选川牛膝优质种源,保证川牛膝的品质。方法本实验以川牛膝主要有效成分杯苋甾酮为指标成分,采用灰色关联度分析方法,对3个道地产区的32个居群川牛膝正品及其混淆品指标成分含量与农艺性状、生态环境、根的显微特征进行关联度分析。结果得出对川牛膝杯苋甾酮含量贡献较大的农艺性状为叶、生态环境因素为海拔和降水量、根的显微构造为栓内层厚度。结论本实验筛选出了优质的川牛膝品种,为川牛膝的品种与质量评价提供科学、可靠的依据。
Objective To screen high-quality provenances of Achyranthes bidentata, to ensure the quality of Achyranthes bidentata. Methods In this experiment, the main active ingredient of Achyranthes bidentata Culex pipiensorum was taken as the index component. The gray relational grade analysis method was used to analyze the content of 32 authentic Achyranthes bidentata var. Chinensis and agronomic traits , Ecological environment, the root microscopic characteristics of correlation analysis. The results showed that the agronomic traits which contributed more to the content of the urethane of Achyranthes bidentata were leaves, the ecological environment factors were elevation and precipitation, and the microstructure of the roots was the inner thion thickness. Conclusion This experiment screened high quality Achyranthes bidentata breeds and provided a scientific and reliable basis for the evaluation of breed and quality of Achyranthes bidentata.
