INFLU ENCE OF BIOANTIOXIDANTS ON SOWING QUALITIES OF SEEDS OF RED CLOVER AND BASTARD ALFALFA

 The study of influence of biologically active compounds on the germination of seeds of perennial legumes is given great importance in the agricultural sector. The research are undertaken on the seed of long-term leguminous herbares: red clover (Trifolium prаtense) and the alfalfa bastard (Medicago varia), which characterize with seed-hardness. As bioantioxidants used: salicylic acid, paracetamol, thiophane (stabilizer СO-3). For seed treatment the working fluid flow rate took up: 100 g of seeds – 1 ml water. Control was treated with distilled water. Salicylic acid and paracetamol were dissolved in water, thiophane dissolved in micellar water (sunflower oil : water – 3 : 7), sodium dodecyl sulfate used as a surface active agent (surfactant) in the critical micelle concentration (CMC) of 8,3 mol/l. Paracetamol studied as active substance and in the form of tablets (auxiliary substances: starch, stearic acid, gelatin). The qualities of seeds are determined: germination energy and laboratory germination. Application of preparations was brought down by seed-hardness at long-term leguminous herbares on 2–21 %. sowing internalss of seed became better: energy of germination increased on 1–15 %, index of laboratory germination on 2–21 %. Treatment of paracetamol (pill, 1 % solution) and micellar water assisted the increase of laboratory germination the on 19 and 21 % accordingly at the alfalfa bastard. Influence of 1 % solution of paracetamol and micellar water assisted the increase of laboratory germination also at the seed of red clover on 3 and 7 % accordingly. Processing salicylic acid, paracetamol and thiophane leads to abnormal seedlings. Consequently, application of preparations can bring down seed-hardness and promote the sowing internalss of seed at the low-germination seed of long-term herbares. Obtained data can be used as a methodological basis for solving issues relating to the selection of bioantioxidants affecting the early stages of plant growth and development.
