SUMMARY
Šucur, J., Popovic, M., Prvulovic, D., Malencic, Ð., Kiprovski, B.: Oxidative stress in soybean seedlings treated with Thymus serpyllum aqueous extract. Biologica Nyssana, 4 (1-2), December 2013: 71-74.The effect of different concentrations (0.05, 0.1 and 0.2%) of Thymus serpyllum L. aqueous extracts on lipid peroxidation process (LP), as well as reduced glutathione content (GSH) in leaves and roots of soybean seedlings were examined 24 and 72 h after the treatment. Our results showed that only highest concentration of the extract used (0.2%) enhanced process of lipid peroxidation, while concentration of 0.1% stimulated GSH accumulation in soybean seedlings.Key words: allelopathy, antioxidants, biopesticides, Glycine max L., Thymus serpyllum L.
