Decreases in Pn indicated O3 stress. O3-induced monoterpene emissions from aboveground were the main volatile defense response. Elevated O3 had little effect on BVOC emissions from belowground parts of either species in spring or summer. In spring, elevated O3 decreased the proportion of carbon emitted as BVOCs relative to that assimilated by photosynthesis (the proportion of BVOC-C loss) at the soil-plant system levels in both species. In summer, elevated O3 resulted in a net CO2-C loss at the soil-plant system level of Scots pine. D
