Abstract
This paper investigates the effects of dielectric barrier corona discharges on the growth of red cabbage sprouts. A custom plasma generator was designed to treat red cabbage seeds with plasma for different durations (15, 30, 45, and 60 seconds) at peak electrical discharge voltage and current across plasma at $12~kV_{peak}$ and $5-14~mA_{peak}$ respectively. The experimental results revealed that plasma-treated seeds exhibited enhanced water absorption capacity and elongated stems compared to the control group, with minor variations in the germination rate. Notably, the 15-second plasma treatment produced the most remarkable growth response, leading to an average stem length of 4.35 cm-1.12 times longer than the control group and a 1.36 times higher water-holding capacity. 15
