Abstract
The results of a study of changes in the sowing qualities of Ocimum basilicum ‘Gvozdichny’ seeds after their treatment with barrier discharge plasma in air for 5, 10, 15 and 20 s are presented, the growth, development, and productivity of the plants grown from them. Plasma treatment has been established to lead to an improvement in the sowing quality from 20% to 83%. With increasing time for seed treatment with plasma, the positive effect on germination energy decreases and on germination increases. Treatment of seeds with plasma for 5, 10 and 15 s does not lead to changes in the productivity of plants grown from them. When plants from seeds treated with plasma for 20 s, activation of growth processes, accelerated development, and increased productivity was observed. Compared to control plants, they had 25% more leaf surface area, 54% more number of leaves, 19% and 71% more wet and dry biomass from the upper vegetative parts of plants, and 33% and 74% more wet and dry root biomass. The increase in the assimilating surface occurred both as a result of a larger number of leaf blades and as a result of an increase in their size, which is not associated with changes in the content of photosynthetic pigments in the leaves of plants. The technology of seed treatment with barrier discharge plasma in air can be used to improve the sowing qualities of seeds and increase the productivity of Ocimum basilicum ‘Gvozdichny’ plants.
