Study of callus induction and cell culture to secondary metabolite production in Hyssopus officinalis L.

The Hyssopus officinalis L. is an important medicinal plant. Antimicrobial and antifungal activities of the essential oil of hyssop have been reported. In this article the effects of explants types, plants growth regulators and elicitors on callus induction and cell culture conditions were studied. In this experiment it was found that there were non- significant differences among hypocotyl and leaf H. officinalis explants for callus induction and callus growth rate. There were significant differences among levels of growth regulators and interaction effect between growth regulators and expellant types for callus induction and callus growth rate. There were significant differences among plant growth regulators levels for callus induction and callus growth rate. Results showed that medium supplemented by N 2 B1 and N0.5B1 showed the highest callus induction and callus growth rate respectively. In this paper it was demonstrated the important role of plant growth regulators and explant types on callus induction in H. Officinalis as a medicinal plants. Also the most important secondary metabolites in H. officinalis were increased in cell culture presence of salicylic acid, citric acid and yeast extract elicitors.
