Figure 3. The appropriate time lag for priming induced accumulation of JA in receiver plants.

Endogenous JA levels were determined in leaves of HIPV-receiver and CV-receiver plants. They were then either treated by the addition of four M. separata larvae for an additional day or maintained for an additional day without a larva. Data represent the mean + standard errors (n = 4–5). There were no significant differences between HIPV-receivers and CV-receivers based on a Tukey-Kramer HSD test (P > 0.05).
