e0“Early leaves were, however, more sensitive to increased O 3 concentrations, with enhanced emission of green leaf volatiles (GLV) and tendencies of both induced leaf senescence as well as poor recovery in the photosynthetic rate between exposures”

Other claims from this paper (4)
- Intervention effect Both early and late summer birch leaves induced sesquiterpene emission after 120 ppb ozone.
- Intervention effect Early leaves showed enhanced green leaf volatile emission at increased ozone concentrations.
- Intervention effect Early leaves tended to recover poorly in photosynthetic rate between ozone exposures.
- Observation Late leaves had more stable photosynthetic rates and responded less to differing ozone levels.
