Mean leaf area of one plant (cm²) measured on the 11th day of cultivation for four biological replicates (up to 20 plants per replicate). “Control” represents plants from untreated seeds of accessions Bab-0 (Background), Masa-0 (Chronic LD), VS-0 (Chronic LD). “Irradiation“ represents plants grown from seeds exposed to acute γ-irradiation at a dose of 150 Gy (Acute HD). Significant difference with exact p-values (Mann–Whitney U-test) are denoted by asterisk. The graphs were created using RStudio v1.4 (R-Tools Technology, Richmond Hill, ON, Canada).
