ANOVA
Values are averages ± SD (n = 3). Letters a–e denote statistical differences between assessed genotypes using Duncan’s multirange mean comparison test (α = 0.05). One-way ANOVA results revealing significant differences between genotypes are presented according to P values as follows: 0.01 ≤ P < 0.05; 0.001 ≤ P < 0.01; and .
