Theoretical model for studying the effect of the JA–SA interaction on induced tea plant volatiles. Compounds in the JNF and JPF groups were only induced by JA pathway elicitors; their emitted amount was respectively negatively and positively correlated with the concentration of JA pathway elicitors. Compounds in the SNF and SPF groups were only induced by SA pathway elicitors; their emitted amount was respectively negatively and positively correlated with the concentration of SA pathway elicitors.
