"In the laboratory conditions the trial on the effect of different nitrogen concentrations in nutritive solution Hoagland No. 3 as affected an energy accumulation and amount of dry matter of roots and above-ground biomass in young plants of winter wheat, the Samanta variety. The trial included the following variants: control variant - 1 N, variant with significant deficit of nitrogen - 0.1 N, the variant with reduced nitrogen content - 0.5 N, the variant with increased nitrogen deficit in solution - 2 N and 4 N. The weight of dry matter of roots and above-ground biomass (stems and leaves) of young plants of winter wheat was studied in selected stages of ontogeny (14.DC, 19.DC, 21.DC, 22.DC, 23.DC, 25.DC, 26.DC, 28.DC and 30.DC). The lowest weight of roots can be found in the variant 2 N when average weight of roots from all samplings was 1.112 g. On the other side, the highest weight of dry matter of above-ground biomass (3.810 g was an average) and thus also total amount of dry matter per one wheat pl" . "P(OC 828.10), Z(MSM 412100002)" .
