Other claims from this paper (7)
- Intervention effect Elevated O3 increased stomatal conductance and O3 uptake in birch.
- Association Higher apoplastic ascorbate concentrations levelled off ozone fluxes to the plasmalemma.
- Intervention effect CO2 enrichment had a minor effect on ascorbate concentrations under elevated ozone.
- Observation Under ambient ozone, ascorbate use ranked from peroxidases through ozone scavenging and oxidases to coniferyl alcohol re-reduction.
- Observation Under elevated ozone, ascorbate use in ozone scavenging exceeded use by oxidases.
- Intervention effect Ozone did not depress ascorbate redox state.
- Mechanism The birch cell wall, plasmalemma and cytosol system maintained apoplastic ascorbate redox status without restricting ozone uptake through stomatal closure.
