Time course of selected VOC emissions measured online using PTR-ToF-MS. Emission data from all chemotypes was averaged according to treatment. Plants that did not receive aphid treatment are represented by the blue lines. Plants that received aphid treatment are represented by the red lines. Where applicable, aphids were applied on day 1; caterpillars were applied on day 4. Leaf biomass was harvested on days 4 and 7. N: no aphid, no caterpillar, A: aphid, no caterpillar, C: no aphid, caterpillar, B: both aphid and caterpillar. a m/z 135.116, representing monoterpenoids such as p-cymene; b m/z 137.133, representing monoterpenes such as limonene; c m/z 151.112, representing terpenoids such as carvone; d m/z 151.149, representing volatile compounds such as (E)-4,8-dimethyl-1,3,7-nonatriene (DMNT); e m/z 153.128, representing oxygenated monoterpenoids such as L-camphor; f m/z 155.144, representing oxygenated monoterpenoids such as eucalyptol; g m/z 205.196, representing sesquiterpenoids such as germacrene D; h m/z 99.081, representing hexenals, also known as green leaf volatiles (GLVs)
