Photoautotrophic propagation of Brazilian ginseng [Pfaffia glomerata (Spreng.) Pedersen]
- Lourdes Iarema, A. C. F. Cruz, +4 authors W. Otoni
- Biology
- Plant Cell, Tissue and Organ Culture (PCTOC)
- 22 March 2012
Pfaffia glomerata (Spreng.) Pedersen is a medicinal species of great interest because it produces the phytoecdysteroid 20-hydroxyecdysone (20E). Generally, because of atypical growing conditions, in… Expand
