From: Extending shelf life: cold plasma as a tool to preserve long-term germination potential of pea seeds
Seed vitality indices of pea seeds achieved in different plasma exposure times. Seed vitality index of (a) poor germinating (50% germ.) and (b) well germinating (90% germ.) plasma-treated (plasma exposure times 10, 20 and 30 s) and reference pea seeds (REF). Bars represent mean values from five independent experiments (each with 50 seeds per variant) ± standard deviation (SD). Different letters indicate statistically significant differences (P < 0.05) based on the LSD test.
