Summary. The aim of the investigation was to study the influence of biological antioxidants on seed germinating capacity of spring wheat (Triticum aestivum) and hull-less barley (Hordeum vulgare.L.) under laboratory conditions. Salicylic acid, paracetamol, and thiophane (stabilizer SO-3) were used as bioantioxidants; distilled water and micellar water were used as controls. Seeds were treated by working fluid with the flow rate of 10 liters of water per 1 ton of seeds. Salicylic acid and paracetamol were dissolved in distilled water, thiophane (it is poorly soluble in water) was dissolved in micellar water (sunflower oil : water – 3: 7). Sodium dodecyl sulfate was used as a surface active agent (surfactant) in the critical micelle concentration (CMC) of 8.3 mol/l. Paracetamol was studied as an active substance and in the form of tablets (auxiliary substances: starch, stearic acid, gelatin). The sowing qualities of seeds were determined: germination energy and laboratory germinating ability. Germinating ability of cereal crops depending on the concentration and effectiveness of bioantioxidant changed in compliance with a complex bimodal dependence. After the treatment by salicylic acid the germination energy and laboratory germinating ability of wheat seeds (laboratory germinating ability was 90 %, germination energy was 80 %) decreased by 4-8 % and 4-14 %, respectively, in comparison with the control variant. The reliable reduction of the values of these indices was noted in the variants with salicylic acid (0.1 %) and paracetamol (0.1 and 1.0 %). Average concentrations (0.5 %) of salicylic acid and paracetamol increased the germinating ability of barley seeds with poor sowing qualities (laboratory germinating ability and germination energy were 72 %), high concentrations (1 %) reduced them. Treatment by thiophane reduced germination energy of wheat seeds by 8-30 %, laboratory germinating ability – by 6-28 %. For barley these decreases were 46-60 % and 8-25 %, respectively.
