Title
Photosynthesis of birch (Betula pendula) is sensitive to springtime frost and ozone

Other claims from this paper (6)
- Intervention effect Frost reduced birch net photosynthesis and stomatal conductance by 60% to 77%.
- Observation Birch net photosynthesis did not fully recover during the following 14 days after frost.
- Mechanism The incomplete recovery was attributed mainly to pigment loss and structural injuries impairing light capture.
- Intervention effect Ozone enrichment worsened frost damage to birch pigments and stomatal conductance.
- Intervention effect Both frost and ozone caused nutrient imbalance and increased soluble leaf proteins.
- Observation Birch genotypes varied greatly in responses to ozone and frost.
