Fig. 4. — Net photosynthetic rate, A (A, D), stomatal conductance, G_s (B, E), and intercellular CO₂ concentration, C_i (C, F),in randomly selected, fully expanded penultimate leaves of Spartina densiflora in response to treatment (A–C) or pre-treatment with a range of Zn concentrations (recovery; D–F) at 0, 1, and 3% NaCl over 90 d. Values represent the mean ±SE, n=10. Different letters indicate means that are significantly different from each other (two-way ANOVA, Zn×salinity; LSD test, P <0.05). Zn, NaCl, or Zn×NaCl in the corner of the panels indicate when the main effects and interaction term are significant.
