Effect of auxin and cytokinin on phenolic content of Baccharis myriocephala DC. (Asteraceae) produced in vitro

A protocol for large-scale in vitro production of Baccharis myriocephala was developed. Total phenolic content was analyzed in plants cultured on MS + 1.0 mg.L-1 of indoleacetic acid (IAA), benzyladenine (BA) or kinetin (KIN). Nodal segments obtained from seeds germinated in vitro on Murashige and Skoog basal medium (MS) were subcultured on MS basal medium, hormone-free or with different growth regulators added: IAA, BA...
