对栽培基质浇灌不同浓度Cd Cl2溶液从而对野菊植株进行镉 (Cd) 胁迫, 测定收获期野菊不同部位和栽培基质中Cd元素含量及野菊花中蒙花苷、总黄酮的含量, 分析野菊植株对Cd元素的吸收特性和Cd元素对药材品质的影响.研究结果表明, 栽培基质Cd元素施加量在0～100 mg·kg-1对野菊生物量影响不显著, 根冠比呈现减小—增大—减小趋势.野菊不同部位Cd元素含量差异显著, 整体上地上部分含量高于地下部分.野菊各部位对Cd元素富集系数变化趋势不同, 地上部分富集系数大于地下部分, 各部位及植株整体呈现先增大后减小趋势, 整体富集系数均大于1.野菊植株地上部分/地下部分转移系数随着栽培基质中Cd元素施加量增加呈现减小—增大—减小—增大的趋势, 并且转移系数均高于1.经过Cd胁迫处理后的野菊花活性成分蒙花苷、总黄酮含量均低于对照, 整体表现为先降低后升高趋势, 但仍显著低于对照, 说明Cd污染会直接导致野菊花药材品质的降低.“,”The Cd stress of Chrysanthemum indicum was treated by different concentrations of Cd Cl2 solution in the culture substrate. The content of Cd in different parts of Ch. indicum and the content of buddleoside and the total flavonoids in Ch. indicum were determined. The absorption characteristics of Cd elements in Ch. indicum were analyzed. And the influence of Cd elements on the quality of the herbs. The results showed that the application of soil Cd in the range of 0-100 mg·kg-1 had no significant effect on the biomass of Ch. indicum, and the root-shoot ratio showed a decreasing-increasing-decreasing trend. The content of Cd in different parts of Ch. indicum was significantly different, and the content of aboveground part was higher than that of underground part. The enrichment factors of Cd elements in different parts of Ch. indicum are different. The enrichment coefficient of aboveground parts is larger than that of underground parts. The whole parts and plants show an increase first and then decrease, and the overall enrichment factor is greater than1. The transfer coefficient of the aerial part/underground part of Ch. indicum showed a decreasing-increasing-decreasing-increasing trend with the increase of the amount of Cd applied in the soil, and the transfer coefficient was higher than 1. The contents of buddleoside and total flavonoids in Ch. indicum after Cd stress treatment were lower than the control, and the overall performance was lower and then increased, but it was still significantly lower than the control, indicating that Cd pollution directly led to the decrease of chemical quality of Ch. indicum.
