Figure 3

The growth parameters of 3-day-old seedlings of barley (a,b) and pea (c), watered with tap water (control: B/P-C), plasma-activated water (PAW) of glow discharge with water cathode and treatment time 1 and 2 min (B/P-GD1 and B/P-GD2), PAW of transient spark discharge with electrospray (B/P-TS) and 2-mM nitric acid (B/P-N). Values are expressed as a mean ± SD from five repeated experimental rounds (one run represents 10 seedlings per variant, n = 50). Different letters represent statistically significant difference at p < 0.05 according to LSD test.
