Analysis of water losses and gas exchange parameters in WT and spd25. (a) Contrast of water loss rate in leaves between WT and spd25. (b) Contrast of relative water content in leaves between WT and spd25. Shown are the mean ± SD from three biological replicates each containing ten plants. * and ** indicate P < 0.05 and P < 0.01, Student’s t-test. (c) Water use efficiency (WUE), (d) Transpiration rate (E), (e) Stomatal conductance (g_s), (f) intercellular CO₂ concentration (Ci), (g) carboxylation efficiency (CE) and (h) net assimilation rate (An) of WT and spd25 at a PPFD of 1200 µmol•m^− 2•s^− 1. Shown are the mean ± SD from three biological replicates each containing ten plants. * and ** indicate P < 0.05 and P < 0.01, Student’s t-test
