Salt tolerance assessment of NS and 35S-OsGGP plants during the vegetative growth phase. Foliar ascorbate concentrations of (A) control and (B) salt-stressed T₄ homozygous NS-1 and 35S-OsGGP-1 plants and T₃ homozygous NS-2 and 35S-OsGGP-2 plants at DAP 40. Bars represent mean ± SEM of six biological replicates. Asterisks indicate statistically significant differences between NS and 35S-OsGGP plants (two-sample t-test; ^**p ≤ 0.01; ^***p ≤ 0.001). The smoothed projected shoot area (sPSA) relative growth rate (RGR) of (C) control and (D) salt-stressed T₄ homozygous NS-1 and 35S-OsGGP-1 plants and of (E) control and (F) salt-stressed T₃ homozygous NS-2 and 35S-OsGGP-2 plants. Salt was applied at DAP 20 and 23. Values represent mean ± half least significant (5%) pairwise difference of six biological replicates. Non-overlapping error bars indicate significant differences at α = 0.05.
