Other claims from this paper (7)
- Intervention effect A 3-hour pH 2.5 fog reduced primary-leaf CO2 assimilation by at least one-third after 24 hours versus pH 6.3 fog.
- Intervention effect A 3-hour fog at pH 3.0 reduced CO2 assimilation at least 20%.
- Intervention effect pH 2.5 acidic fog increased primary-leaf stomatal resistance by more than 37% relative to pH 6.3 fog.
- Intervention effect Stomatal resistance under pH 3.0 fog increased at least 27%.
- Intervention effect Internal CO2 concentrations did not differ significantly between control and acid-fogged plants at any pH.
- Method / resource Standardizing by similar CO2 assimilation rates enabled statistical separation of photosynthetic variables relative to unstandardized designs.
- Observation Lesion damage after pH 2.0 fog usually progressed from upper to lower epidermis.
