Total ascorbate levels and reduction states of ascorbate in LTC- (top) and STC-primed (bottom) plants immediately and 2 days after priming and triggering. The data were analyzed by Student’s t-test and by ANOVA (Tukey’s test; p < 0.05, n = 10). Significant differences to naïve plants are labeled with an asterisk. No significant differences were observed after triggering. For C, P, T and PT plants the same color scheme as in Fig. 1 was applied
