Low-plasma has been recently investigated in the field of agricultural science as an alternative to
the traditional pre-sowing seed treatment such as physical scratching, heat treatment and
chemical treatment. The influence of low-plasma treatment on barley seeds(Hordeum vulgare L.)
has been investigated by using a surface dielectric barrier discharge at atmospheric pressure and
room temperature. Naked barley cultivars were Saessal and Saechal, covered barley cultivars
were Hyeyang and Quenal1. We investigated the seed germination, surface morphology and
functional material changes. Plasma treatment induced significant changes in the seed surface
which was related to water permeability into the seeds. Seed surface was cracked and eroded
after plasma treatment. Germination ratio was not significantly different according to plasma
treatment. Hypocotyl and root length of barley that was treated for 3 minute with plasma
increased. But they did not show the any tendency. GABA content of Saessal and Heyang did not
show a big difference by plasma treatment, while in Saechal and Quenal showed an increasing
tendency. After 3 germination days, GABA content increased approximately five times. DPPH
was slightly decreased as plasma treatment time increased in seed and germination. However, the
amount was different according to crops.
