Comparisons of steady-state isoprene emission temperature dependencies at current ambient CO2 concentration of 390 μmol mol−1 and at high CO2 concentration of 800 μmol mol−1. Error bars give sd of five replicate experiments. The isoprene emission rate is significantly larger under ambient than under high CO2 at 22°C and 30°C, but no significant CO2 effect is observed at 35°C and 40°C (P > 0.05, ANOVA).
