Figure 2.

Effect of M1 (10⁹ cells/mL) and M2 (10⁹ cells/mL) and their combinations on photosynthetic pigments (A) total chlorophyll content, (B) total carotenoid content, and (C) total xanthophyll content in 45-day-old L. esculentum under Cd metal stress. Data is presented as means of 3 replicates ± S.D (standard deviation) and HSD values. F ratio values, * indicates significance at p ≤ 0.05 and ** indicates significance at p ≤ 0.01). Different letters on the table indicate that mean values of treatments are significantly different at p < 0.5 according to Tukey’s multiple comparison test (CN—control, Cd—cadmium, M1—P. aeruginosa, M2—B. gladioli, T—treatment, D—Dose, H.S.D—honestly significant difference).
