Morphophysiological in vitro performance of Brazilian ginseng (Pfaffia glomerata (Spreng.) Pedersen) based on culture medium formulations

Pfaffia glomerata has potential pharmacological and medicinal properties due to the production of a secondary metabolite known as the phytoecdysteroid 20-hydroxyecdysone (20E). There have been increasing efforts for massive in vitro propagation of Pfaffia plants due to high extractivism and overharvesting of this species. Research on the species has shown that photoautotrophic cultivation can improve the production of 20E. In addition, other...
