SEEDS AFTER THEIR TREATMENT WITH ELECTROCHEMICALLY ACTIVATED WATER O.A. Pasko Tomsk National Research Polytechnical University, Tomsk 634050, Russia e-mail: oap@sibmail.com Received June 9, 2010 S u m m a r y Numerous data confirm the high effect of electrochemically activated water application in agriculture. <...> The author studied the influence of preplant treatment of amaranth seeds by electrochemically activated water on activity of respiratory enzymes, the substrates content, the germination energy and the growth strength. <...> It was established, that physico-chemical changes of water after electrolysis induce in seeds different metabolic processes. <...> High content of soluble sugars on the background of anaerobiosis in variants with mixture cathodic and anodic liquors and catholyte only promotes to glycolytic process, but accumulated metabolite pool permit to use them in more various chemical conversions. <...> The increased content of hormones accelerates the growth processes, determines enhanced division and cell distension, the intensive course of initial stages of plant development (increase of germination energy and growth strength in seeds). <...> Bioactive properties of electrochemically activated water (EAW) are being studied since 1965 (1). <...> Using EAW for presowing treatment of cucumber seeds, it was found to improve the quality of seedlings, yield and immunity of plants, as well as a product quality. <...> Later, the efficiency of EAW was confirmed on maize, buckwheat, millet, sunflower, oats, wheat, barley, sweet peppers, tomatoes, radish, lettuce, onions, and cabbage (2-4). <...> Seed treatment with EAW has opened great prospects for growing medicinal plants with prolonged innate seed dormancy (5). <...> Anolyte (acidic modification of EAW) is effectively utilized in reclamation of alkaline soil (6), so it makes unnecessary to deliver acids right to the treated area and improves the efficiency of soil treatment (7). <...> There is evidence that discrete alternated watering with catholyte (alkaline modification of EAW) and anolyte reduces water consumption by 10% and mineral depletion by 20% (8). <...> Using anolyte is 500 times cheaper than chemical preservatives of foreign <...>
