Improving the conditioned qualities of sunflower seeds by pre-sowing treatment with a pulsed electric field

The article reflects the results of scientific studies of responsiveness to germination and germination energy of sunflower hybrid seeds to the electrophysical effect of a pulsed electric field with different intensity and exposure time. Seeds of sunflower hybrids NK Neoma and ES Petunia were taken for research. During the experiments, pulse field intensity of 2, 4, 8, 10 kV/cm, pulse duration of 40 microseconds, electric field exposure time of 15, 30, 60, 90, 105 seconds were taken. Optimal modes for processing sunflower seeds with a pulsed electric field have been experimentally established to increase the conditioned qualities – seed treatment for 90 seconds at a field intensity of 6 kV/cm or treatment at a field intensity of 8 kV/cm for 60 seconds
