Thirty-day-old plants grown in hydroponic culture were subjected to moderate salinity (75 mM NaCl). Photosynthesis determinations were performed after 24 days. Photosynthetic rate (A_N), stomatal conductance (g_s), mesophyll conductance (g_m), substomatal CO₂ concentration (C_i), photorespiration rate (PR), effective (PhiPS2) and maximum (F_v/F_m) quantum yield of chlorophyll fluorescence of PSII, maximum carboxylation rate of Rubisco (V_{c max}), maximum electron rate (J_max) and triose phosphate utilization rate (TPU) values in 35S::AtCDF3 (L 2.3) plants are presented. Each measure is the mean of ten independent measurements in different plants. Six different plants were used to perform A-Cc curves to obtain V_{c max}, J_max and TPU.

For each genotype and parameter, different letters indicate significant differences (P < 0.05). Significant differences among genotypes at a given condition are indicated by an asterisk.
