    Abstract

    The effect of elevated atmospheric CO₂ mixing ratios on Biogenic Volatile Organic Compound emissions from Corymbia citriodora (Lemon Scented Gum, Spotted Gum) and Tristaniopsis laurina (Water Gum or Kanooka) was determined for the first time through the combination of Solid-Phase Microextraction (SPME), Gas Chromatography-Flame Ionisation Detection (GC-FID) and an environment chamber. For C. citriodora, elevated atmospheric CO₂ led to a decrease in the emission rate of α-pinene, β-pinene, eucalyptol, citronellal and β-caryophyllene. Elevated CO₂ had no effect on the emission rate of citronellol. For T. laurina, elevated CO₂ led to a decrease in the emission rate of α-pinene but the emission rates of β-pinene, limonene, eucalyptol and citronellol were unaffected. The results obtained in this work confirm that the effect of elevated atmospheric CO₂ on plant BVOC emissions is species-specific.
