The effect of Satureja montana L. aqueous extract on soybean seedlings

摘要

The aim of this study was to examine the impact of Satureja montana L. aqueous extract on soybean antioxidant properties so as to assess its possible side effects when applied as biohebicide in soybean organic production. The effects of two concentrations (0.1% and 0.2%) of S. montana aqueous extract on the activity of the antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT) in leaves and roots of soybean ( Glycine max L.) seedlings were examined 24, 72 and 120 h after the treatment. Our results showed that the significant increase in the catalase activity was recorded in roots of soybean treated with both concentrations of the extract used. On the other hand, both concentrations of S. montana aqueous extract stimulated the significant increase of the superoxide dismutase activity in leaves and roots of soybean. Higher activity of the antioxidant enzymes in the roots of soybean compared with activity of the antioxidant enzymes in leaves showed that roots were more affected than leaves.
