The sowing qualities of seeds of Ocimum basilicum “Gvozdichnyi” after their treatment with dielectric-barrier discharge plasma for 5, 10, 15 and 20 s in an argon atmosphere and morphogenesis and productivity of plants grown from them have been studied. It has been shown that the plasma treatment of seeds increases their germination energy and germination by 32–97%, the magnitude of changes being determined by the treatment time. Plants grown from seeds treated for 10 s were characterized by intensive growth and increased productivity relative to control. At the end of the growing season, they had a 40% greater number of leaves, a 28% greater area of the assimilating surface, a 21% greater biomass of the aerial part, and a 3 times greater biomass of the roots.
