The content of metabolites with antioxidant power (total phenolic compounds (A) and flavonoids (B), WS-AOM (C) and LS-AOM (D)) and antioxidant potential (DPPH (E), FRAP (F)) in S. rebaudiana plantlets in vitro propagated on MS medium, on MS medium with BAP, and on MS medium supplemented with various concentrations (1, 10, 50, 100 mg L⁻¹) of aminoacid nanofibers enriched with 1% and 2% colloidal Ag (NF-1%Ag, NF-2%Ag). Values are means ± SE, n = 20; different letters indicate significant differences assessed by the Fisher LSD test (p ≤ 0.05) after performing ANOVA one-way analysis. We used the letter ‘a’ or “A” for the lowest data value and ascending to the next letters for higher-data values. The statistical analysis of NF-1%Ag (uppercase) and NF-2%Ag (lowercase) was performed separately.
