The study presents the results obtained from the univariate series of laboratory experiments, conducted in 2009-2010. In the experiments, the effect of water constant magnetic field stimulated and unstimulated water on germination and initial growth of seedlings of pea, maize, yellow lupine and cucumbers were studied. The results confirmed the reaction varied seed plant species assessed on the type of water used. Beneficial effects of the use of magnetized water highlighted to boost growth and germination of seed maize and cucumbers. And in the case of the latter species also increases in the dry weight of the aboveground parts of seedlings. For the adverse effect of magnetized water should be considered to reduce the amount of seedlings of pea and yellow lupine and the dry weight of the underground part of the seedling corn. ...
