Other claims from this paper (12)
- Intervention effect Stomatal conductances of abaxial and adaxial epidermes under optimal conditions were not significantly affected by growth under elevated CO2.
- Intervention effect Stomatal regulation of gas exchange was better under elevated CO2.
- Intervention effect Leaf photosynthetic rate of elevated CO2 plants was similar to control plants when both were measured under normal CO2.
- Intervention effect Leaf photosynthetic rate of elevated CO2 plants was higher than control plants when both were measured under elevated CO2.
- Intervention effect Photosynthetic rate of elevated CO2 plants was much higher than that of control plants when measured at their respective growth CO2 concentration.
- Intervention effect The higher photosynthetic rate resulted in a higher growth rate of elevated CO2 plants.
- Intervention effect Chlorophyll a and b contents and activities of the whole electron transport chain and of photosystem II were not markedly affected by growth under elevated CO2.
- Intervention effect Maximum efficiency of PSII (Fv/Fm) was even slightly increased under elevated CO2.
- Observation No down-regulation of photosynthesis occurred in transplanted plants grown for 4 weeks under elevated CO2.
- Intervention effect Contents of beta-carotene and xanthophyll cycle pigments were lower in elevated CO2 plants.
- Intervention effect The degree of de-epoxidation of xanthophyll cycle pigments was not changed or was even lower after transfer to ex vitro conditions.
- Observation No photoinhibition occurred in the elevated CO2 plants.
