The influence of cytokinins and culture conditions including medium volume, harvest time and elicitation with abiotic elicitors (SA/MeJ) have been studied for the optimal production of biomass and withanolides in the multiple shoot culture of Withania somnifera. Elicitation of shoot inoculum mass (2 g 1-1 FW) with SA at 100 μM in the presence of 0.6 mg 1-1 BA and 20 mg 1-1 spermidine for 4 h exposure time at the 4th week in 20 m1 liquid medium recorded higher withanolides production (withanolides A [8.48 mg g-1 DW], withanolides B [15.47 mg g-1 DW], withaferin A [29.55 mg g-1 DW] and withanone [23.44 mg g-1 DW]), which were 1.14 to 1.18- fold higher than elicitation with MeJ at 100 μM after 5 weeks of culture. SA-elicited cultures did not exhibit much variation in biomass accumulation when compared to control. This cytokinin induces and SA-elicited multiple shoot culture protocol provides a potential alternative for the optimal production of biomass and withanolides utilizing liquid culture.
