摘要：

An in vitro propagation system was developed for Echinacea purpurea L. (purple coneflower), a medicinal plant commonly used in the treatment of colds, flu and related ailments. Root organogenesis from Echinacea purpurea hypocotyl explants was effectively induced by indolebutyric acid. Indoleacetic acid was found to be less effective than indolebutyric acid while treatments with naphthaleneacetic acid were ineffective for induction of root organogenesis. The results of this study have established a micropropagation system for Echinacea purpurea that will provide axenic plant material for further investigations into medicinally active biochemicals and the mass production of high-quality Echinacea purpurea root tissues for the commercial market.
