- Plants of soybean (Glycine max L.) cv. Augusta grew in the soil with addition of Ni in the concentration of 80 (C-80) or 120 mg∙kg-1 dry mass (C-120) or without Ni (C-0), and they were subjected to UV-B (300 nm – 315 nm) dose of 1.8 kJ m-2 d-1 for 28 days. The addition of nickel into soil in the concentration of 120 mg kg-1 (C-120) caused a decrease of the plant height by 35% compared to the control (C-0), and in the presence of UV-B (U-120) – by 43%. The shoot fresh and dry mass in the C-80 and C-120 plants were lower by 33% and 52% than in the C-0. In the presence of Ni, the intensity of net photosynthesis decreased by 55%. UV-B caused an increase of flavonoid content by 25% compared to the control (C-0), and Ni induced a reduction in the content of these compounds from 20% to 40%.
