Growth, secondary metabolite production and antioxidant enzyme response of Morinda citrifolia adventitious root as affected by auxin and cytokinin (2010, unknown): “The highest dry mass production from adventitious roots of Echinacea aungustifolia was achieved at 2 mg l-1 IBA when compared to NAA (Wu et al. 2006).”
Induction mechanism of adventitious root from leaf explants of Morinda citrifolia as affected by auxin and light quality (2010, methodology): “The contents of total phenolics and flavonoids were analyzed spectrophotometrically from the same root ethanolic extract according to Wu et al. (2006).”
Sucrose-induced osmotic stress affects biomass, metabolite, and antioxidant levels in root suspension cultures of Hypericum perforatum L. (2010, methodology): “For the adventitious root cultures of Echinacea angustifolia, a relatively higher sucrose concentration of 7% (w/v) was found to be more favorable for biomass accumulation, whereas 5% (w/v) sucrose was best for the production of phenols and flavonoids (Wu et al. 2006).”
Application of an airlift bioreactor system for the production of adventitious root biomass and caffeic acid derivatives of Echinacea purpurea (2009, methodology): “The concentration of the total phenolics in the roots was determined spectrophotometrically [ 15 ].”
