Abstract: | We aimed to assess the potential effects of fumigation by methyl salicylate (MeSA) on plant monoterpene production and emissions.
We evaluated monoterpene production and emissions both by chromatographic and proton transfer reaction mass spectrometry at
the whole plant-and leaf-scales, in MeSa-fumigated (ca. 60 mm3 m−3 in air) and control (without MeSa fumigation) holm oak (Quercus ilex L.) plants exposed to temperatures ranging from 25 to 50 °C. The MeSa-fumigated plants showed ca. 3–4-fold greater leaf monoterpene concentrations and emission rates than the control plants between the temperatures of 25
to 45 °C. |
