| description | The largest global source of volatile organic compounds (VOCs) in the
atmosphere is from biogenic emissions. Plant stressors associated with a
changing environment can alter both the quantity and composition of the
compounds that are emitted. This study investigated the effects of one
global change stressor, increased herbivory, on plant emissions from five
different coniferous species: bristlecone pine (<i>Pinus aristata</i>), blue spruce
(<i>Picea pungens</i>), western redcedar (<i>Thuja plicata</i>), grand fir (<i>Abies
grandis</i>), and Douglas-fir (<i>Pseudotsuga menziesii</i>). Herbivory was simulated
in the laboratory via exogenous application of methyl jasmonate (MeJA), a
herbivory proxy. Gas-phase species were measured continuously with a gas
chromatograph coupled to a mass spectrometer and flame ionization detector
(GC–MS–FID). Stress responses varied between the different plant types and
even between experiments using the same set of saplings. The compounds most
frequently impacted by the stress treatment were alpha-pinene, beta-pinene,
1,8-cineol, beta-myrcene, terpinolene, limonene, and the cymene isomers.
Individual compounds within a single experiment often exhibited a different
response to the treatment from one another. |
