Abstract

Stevia rebaudiana Bertoni is an herbaceous and perennial plant with an important commercial use. In the present study, we investigated effects of various SA and MJ concentration on fresh weight, TFC, TPC, PAL enzyme and antioxidant activity. Leaf explants were placed on Murashige and Skoog (MS) medium and exposed to elicitors (0, 50, 100, 200 and 250 μ M SA and MJ). 2 mg. l BA and 2mg. l NAA used for callus induction. Results showed that, when elicitors applied to cell culture, phenyl propanoid compounds, antioxidant activity and PAL enzyme activity were increased. Application of MeJA and SA at 100 and 200μ M had the highest effect on the production of measured TPC whereas TFC obtained in 100 μ M of both elicitors. Moreover, maximum antioxidant activity was obtained in 200 μ M of SA and MJ. A positive correlation between antioxidant activities, TFC and TPC showed that phenolic compounds might play a key role in antioxidant activity of Stevia. Although it was noteworthy remarkable that accumulation of Phenolic compounds, antioxidant activity and PAL enzyme activity was in positive correlation, that may be sign of key role of PAL on phenolic compounds production. Observed negative correlation of elicitors’ application with callus fresh weight indicated that under real or pseudo stress condition the plant cell tried to balance primary and secondary metabolites. Based on the obtained results, it can be concluded that poly phenolic compounds production, can be strongly changed by application exogenous elicitor compounds.
