- Association Ozone injuries to Pinus strobus were more frequent and severe in 1967 than in 1966
- Intervention effect Ozone at 7 ± 1 pphm for four hours induced characteristic symptoms on pine foliage
- Intervention effect Ozone at 3 ± 1 pphm for 48 hours induced characteristic symptoms on pine foliage
- Intervention effect Fumigation with water mist increased ozone sensitivity of pine needle tissue
- Intervention effect High ozone concentrations caused general foliar injury in both susceptible and resistant trees
- Observation Symptoms from high ozone doses were unlike field symptoms or those from low-dose fumigation
