Abstract

The effect of different triazole compounds, viz., triadimefon (TDM) and hexaconazole (HEX) treatments on the antioxidant metabolism of Solenostemon rotundifolius Poir., Morton plants was investigated in the present study under pot culture. Plants were treated with TDM at 15 mg l-1 and HEX at 10 mg l-1 separately by soil drenching on 80, 110 and 140 days after planting (DAP). The plants were harvested randomly on 90, 120 and 150 DAP for determining the effect of both the triazoles on non-enzymatic antioxidant contents like ascorbic acid (AA), reduced glutathione (GSH) and α-tocopherol (α-toc), activities of antioxidant enzymes like superoxide dismutase (SOD) and ascorbate peroxidase (APX). All the analyses were made in leaf, stem and tubers of both control and treated plants. It was found that both these triazole compounds have profound effects on the antioxidant metabolism and caused an enhancement in both non-enzymatic and enzymatic antioxidant potentials under treatments. These results suggest that, the application of triazoles may be a useful tool to increase the antioxidant production in S. rotundifolius and thereby make it an economical food crop.
