The influence of pre-sowing seed treatment with a use of microelements and barrier discharge plasma on productivity of Cucumis sativus

The influence of pre-sowing seed treatment of Cucumis sativus L. F1 ‘Kurazh’ seeds, treated with microelements (control) and barrier discharge plasma on the laboratory germination and germination energy, morphogenesis and productivity of plants grown from them was studied. The active power of the discharge was ∼7 W at the amplitude of high voltage pulses of voltage of 9 kV and the frequency of their repetition of 2 kHz, the time of seed plasma treatment estimated to 10, 30 and 60 s. Compared to the control group, all the experimental seeds were characterized by improved seeding qualities as well as by activation of growth processes in seedlings. There were no significant changes in the formation and development of reproductive organs at the beginning of vegetation (up to 50 days). Subsequently, in all the experimental plants, part of the ovaries was destructed, taking into account that the less time the seeds were treated with plasma, the more and sooner ovaries were destructed in the plants which were grown from them. The productivity of the experimental plants compared to the plants grown from seeds treated with microelements estimated to 60, 66 and 67%, respectively, which is possibly due to the depression of the immune system of plants during the double pre-sowing treatment of seeds.The influence of pre-sowing seed treatment of Cucumis sativus L.
