[Effect of AgNO3 on the production of flavonoids by the culture of Ononis arvensis L. in vitro].

The study tested the effect of abiotic elicitor, AgNO3, in different concentrations, on the production of flavonoids in the callus culture Ononis arvensis L. The use of this abiotic elicitor proved to be good to increase the production of flavonoids in in vitro culture. The maximal production was achieved after a 24-hour elicitation with AgNO3 in a concentration c1 (0.5 mg/1)--an increase by 934% versus the control (without the elicitor's action).
