Biosynthesis of antioxidative enzymes and polyphenolics content in calli cultures of L. in response to auxins and cytokinins.

L. is one of the therapeutic herbs containing various polyphenolics, which is used for multiple medicinal purposes. In this study, plant growth regulators (PGRs)-induced calli cultures from seed-derived leaf explants were exploited for the production of stress enzymes and polyphenolics.
