Descrição: The allelopathic potential of two cultivars of Helianthus annuus, Lech and Ogrodowy, was studied. Leaf extracts of sunflower at 2,5, 5, and 10% concentrations were applied to determine their effect on mustard seed germination and seedlings growth under laboratory conditions. Increasing concentration of aqueous extracts of sunflower inhibited seed germination. Almost complete failure of germination was observed in the presence of 10% extract from sunflower cv. Ogrodowy. The decrease in germinability was well correlated with increased membrane deterioration, assayed as electrical conductivity, and enhanced lipid peroxidation, detected as increased malondialdehyde concentration.
