Chinese cabbage plants, Vesniyanka cultivar, were grown under natural illumination in normal radiation and were placed in condition of periodic y-irradiation produced by the GAMMA-BREEZ source. The irradiation was carried out each 7 days for 4 hours with dose power 5 mSv/h. The summarized dose during all vegetation time was 80 mSv. The root zone of plants was moistened with water containing the different concentrations of deuterium. Radioactive influence on plants did not take effect in yielding abilities and ascorbic acid content in leaves. The reduction of deuterium concentration in water caused the plant productivity was twice as much as before, but otherwise it resulted the active accumulation of nitrates in leaves.
