The growth of Lavandula vera MM plant cell suspension culture and rosmarinic acid biosynthesis under elicitation with benzothiadiazole and methyl jasmonate were investigated. Upon elicitation with 50 μM methyl jasmonate, the production of rosmarinic acid was enhanced 2.4-fold (3348 mg/l) compared to the non-elicited cells. The influence of benzothiadiazole on rosmarinic acid biosynthesis was weaker and 12 h after its addition the achieved yields were 20–30% higher compared to the control variant at this time. The influence of both elicitors on rosmarinic acid secretion into the culture medium was also discussed.
