Abstract

Cnidoscolus chayamansa is a plant widely used as food with potential medicinal applications. Plant tissue culture enables the production of secondary metabolites from plants in a sustainable manner. The aim of this work was to establish a callus culture of C. chayamansa using leaf explants, which, in the future, can be used to obtain whole extracts or specific compounds of interest. Different concentrations and combinations of 6-Benzylaminopurine (BAP) and 2,4-Dichlorophenoxyacetic Acid (2,4-D) in Murashige and Skoog (MS) culture medium were evaluated for their ability to support callus induction from immature leaf explants. Highest callus yield (100%) was achieved when leaf explants were incubated in MS medium supplemented with BAP (5.0 mg L-1) and 2,4-D (2.5 or 5.0 mg mL-1). A reduced rate of callus induction (75%) was observed when leaf explants were exposed to lower concentrations (0.5 mg L-1) of BAP or 2,4-D. The calluses obtained in this work can be used as a biotechnological alternative for in vitro propagation of C. chayamansa and for obtaining extracts or compounds with a possible pharmacological application.
