Title
Effect of fertilization on ozone‐induced changes in the metabolism of birch (Betula pendula) leaves
W. LANDOLT; M. S. GÜNTHARDT‐GOERG; I. PFENNINGER; et al. New Phytologist 1997. doi:10.1046/j.1469-8137.1997.00843.x
Other claims from this paper (13)
- Intervention effect High fertilization enhanced PEPC and Rubisco activities about threefold.
- Intervention effect Significant ozone effects generally occurred only in older leaves under low fertilization.
- Intervention effect Ozone enhanced sucrose, glucose and fructose in older low-fertilization leaves.
- Intervention effect Ozone increased starch-granule numbers along minor veins in both fertilizer regimes.
- Mechanism Ozone effects suggest decreased or inhibited phloem loading.
- Intervention effect Ozone-exposed plants showed increased PEPC activity and malate levels.
- Intervention effect Ozone-exposed plants had enhanced malate levels.
- Mechanism Metabolic changes may reflect carbon redirection towards anaplerotic detoxification and repair, with enhanced respiration.
- Intervention effect Ozone enhanced respiration.
- Intervention effect Ozone markedly reduced the root:shoot biomass ratio under low fertilization.
- Intervention effect High-fertilization plants had no significant ozone response in root:shoot biomass ratio.
- Intervention effect Ozone decreased inositol in both fertilizer treatments.
- Observation Well-fertilized plants appear better able to cope with ozone effects on metabolism.
