The results of studies of antiradical activity by the method of DPPG absorption by extracts of rye, wheat, and oat seedlings enriched with selenium from aqueous solutions of sodium Selenite 0.001, 0.005, 0.01, 0.05% concentrations within 24 hours. Selenium inhibits the rate of reaching the "plateau" of the DPPG absorption reaction, but increases the anti-radical activity of grain seedlings. The total content of phenolic compounds in grain extracts was determined spectrophotometrically. The influence of selenium on the growth processes of wheat, rye, and oats is shown. Concentrations of 0.001 and 0.005% have a stimulat-ing effect on the length of the roots and coleoptile of grain crops. At a concentration of 0.05%, selenium is deposited as granules in the cells of the germ of the grain. Oats are the most sensitive crop to selenium, and wheat and rye are promising as crops that can exhibit antiradical properties and source of organic forms of selenium.
