Models examined the effect of Norway spruce (P. abies) clone, MeJA treatment (MJ: 0, 50 mM) and their interaction, on absolute terpene amounts when plants had not been (No fungus exposure) or had been exposed to E. polonica (Exposed to fungus) following MeJA treatment. Significant effects are in bold (P < 0.05).
