Figure 6.

Gas exchange measurements in leaves of purple basil cv. Red Rubin at 0 and 7 days after bacterial treatment (0 DAT and 7 DAT, respectively) and at 1, 3, and 6 days after water stress (1 DAS, 3 DAS, and 6 DAS, respectively): (a) steady state photosynthetic CO₂ assimilation rate (A); (b) stomatal conductance (g_s); (c) intercellular CO₂ concentration (Ci); (d) transpiration rate (E). Values are means ± SE (n = 10). Different letters indicate significant differences among bacterial treatments and control (one-way ANOVA with Fisher’s LSD test, p ≤ 0.05).
