Other claims from this paper (8)
- Intervention effect Chronic ozone exposure reduced photosynthesis in Coffea arabica.
- Intervention effect Chronic ozone exposure impaired redox balance in Coffea arabica.
- Observation Coffea arabica showed increased antioxidants under ozone exposure.
- Observation Coffea arabica showed accumulation of amino acids under ozone exposure.
- Observation Coffea arabica showed elevated fatty acids under ozone exposure.
- Mechanism The compensatory adjustments partially reduced oxidative damage in Coffea arabica.
- Observation The leaf adjustments did not prevent leaf injury in Coffea arabica.
- Mechanism Chronic ozone is likely to weaken leaf cell walls in Coffea arabica by reducing lignin, cellulose and pectin.
