The activity of protease (A) and glucanase (B) in 3-day-old maize seedlings after Cold Atmospheric Pressure Plasma (CAPP) treatment of grains. Variants: C–control/untreated maize grains; O30–O300: maize grains treated with plasma generated in an oxygen atmosphere for 30, 60, 90, 120, 180 or 300 s; A30‒A300: maize grains treated with plasma generated in ambient air for 30, 60, 90, 120, 180 or 300 s; N30–N300: maize grains treated with plasma generated in a nitrogen atmosphere for 30, 60, 90, 120, 180 or 300 s. In the case of N90 variant seedlings lagged significantly in development and in N120–300 variants, the maize grains did not germinate, so they are not shown in the graph. Different letters indicate significant difference at p-value < 0.05, bars are means of ten experimental runs (one run represents 50 grains per variant; three 1.5 g mixed samples were analyzed per one experimental run and each variant for protease and glucanase activities) ± SD according to LSD ANOVA test.
