Direct and indirect evaluation of leaves chlorophyll content and chlorophyll fluorescence. (A) Iron deficiency chlorosis visual symptoms with both rootstocks and all treatments (N1A0/+Fe; N1A0/-Fe; N1A1/+Fe; N1A1/-Fe), (B) total chlorophyll concentration in young leaves, (C) non-destructive assessment of chlorophyll content by measuring the SPAD index, and (D) maximum photochemical rate of photosynthesis (FvFm). Values shown are means ± standard error and significant differences between treatments for each rootstock are indicated with different letters. (α < 0.05, Welch-ANOVA and Tukey or Games-Howell post hoc test, N = 5 per treatment and rootstock)
