Figure 8: Short term (6 h, 24 h) and long term (3 days, 7 days) salt pre-treatment does not prime plants for an increased induced response in terms of A. PPO and B. TPI levels to H. zeaherbivory. Bars represent mean (± SEM) (n = 8-11, mixed-effects analysis, * P < 0.05, ** P < 0.01, ***P < 0.001, **** P < 0.0001).
