Level of DNA damage in 3-day-old maize seedlings detected by the neutral comet assay and its modification with enzyme formamidopyrimidine glycosylase (Fpg) after the treatment of maize grains with Cold Atmospheric Pressure Plasma (CAPP) generated in ambient air (A), oxygen (B) or nitrogen (C). 0 s—negative control (NC; no treatment); 30, 60, 90 and 120 s—treatment of grains with CAPP for 30–120 s; at least 100 nuclei were analyzed per slide. The data were analyzed using the statistical method LSD ANOVA and comparisons between the mean values were considered significant at p 0.05. Different letters indicate significant difference at p-value < 0.05, bars are the means of three experimental runs ± SD.
