摘要:  川芎是著名川产道地药材,由于对镉富集性强,其药用品质安全性及有效性备受关注,如何降低川芎根茎中的镉含量成为目前川芎产业发展的关键之一。阐述了川芎镉污染现状、镉吸收积累规律,进而着重分析了川芎镉污染的影响因素以及降低川芎根茎中镉含量的措施。在土壤修复技术无法短时间内实现川芎安全生产的情况下,提出可通过分子技术和辐射诱变技术相结合选育低富集镉川芎品种的思路,以期为解决川芎重金属污染问题提供参考。

关键词: 川芎, 重金属, 镉污染, 降镉措施, 低富集镉品种

Abstract: Ligusticum chuanxiong Hort.is a famous Dao-di herb in Sichuan,due to its high concentration of cadmium,the safety and effectiveness of its medicinal quality have attracted much attention.How to reduce the cadmium content in the Ligusticum chuanxiong Hort.has became one of the keys to the development of the Ligusticum chuanxiong industry.The paper described the cadmium pollution situation of Ligusticum chuanxiong and the law of cadmium absorption and accumulation,and then emphatically analyzed the influence factors of cadmium pollution of Ligusticum chuanxiong Hort.and the measures to reduce the cadmium content.Under the condition that the soil remediation technology cannt realize the production of Ligusticum chuanxiong safely,in a short time,suggesting that the cultivar of Ligusticum chuanxiong with low concentration of cadmium can be selected through the combination of molecular technology and radiation mutagenesis technology,hoping to provide reference for solving the problem of heavy metal pollution caused by Ligusticum chuanxiong.

Key words: Ligusticum chuanxiong Hort., Heavy metals, Cadmium pollution, Cadmium reduction measures, Low cadmium-enrichment varieties
