The purpose of this study was to accelerate germination of plant seeds with application of a high frequency alternating electric field. In the present study we show that low-intensity (0.05–1 Vpp/cm) and high frequency (10–100 MHz) alternating electric fields accelerate seed germination. We found that 1 Vpp/cm (peak to peak voltage/cm), 100 MHz alternating electric field application for 10 h significantly shortened germination time of arugula, Japanese mustard spinach, and pea seeds, respectively. In arugula and Japanese mustard spinach seeds at 24 h incubation and pea seeds at 32 h incubation after beginning of the application, the germination rates of the electric field applied plant seeds were enhanced 1.5–2.2 times compared to the untreated seeds, respectively. After 72 h of the incubation, the 1 Vpp/cm, 100 MHz alternating electric field for 10 h significantly increased 1.4 folds of culm lengths in the arugula, the Japanese mustard spinach, and the pea seeds compared with those of the untreated seeds.
