英文摘要: We measured monoterpene emissions from needles of hybrid larch F1 (Larix gmelinii var. japonica × Larix kaempferi) to evaluate the response of monoterpene emission rates and their composition to elevated CO2 (600 μmol mol−1) and O3 (60 nmol mol−1) conditions. The dominant monoterpenes were α-pinene and β-pinene. The emission rate of total monoterpenes significantly decreased under elevated CO2 conditions (P < 0.05). The ratio of carbon emission in the form of monoterpenes to photosynthetically fixed carbon also significantly decreased under elevated CO2 conditions. By contrast, elevated O3 did not significantly affect the emission rate of total monoterpenes. The ratios of α-pinene/β-pinene, limonene/β-pinene, and myrcene/β-pinene were all significantly decreased by O3 exposure (P < 0.05). High reactivity of α-pinene, limonene, and myrcene when combining with O3 may be able to mitigate oxidative damage inside the larch needles. No significant combined effects of elevated CO2 and O3 on individual or total monoterpene emissions were detected. © 2016 Elsevier Ltd Citation statistics:
