Other claims from this paper (14)
- Intervention effect Elevated CO2 resulted in a sustained increase in the rate of CO2 assimilation in wheat compared with ambient CO2.
- Intervention effect After roughly 6 weeks of elevated CO2, photosynthetic rate declined slightly, most markedly in winter cultivars.
- Intervention effect Elevated CO2 decreased stomatal conductance in wheat.
- Intervention effect Elevated CO2 improved the instantaneous water use efficiency of individual wheat leaves.
- Intervention effect CO2 enrichment stimulated shoot and root growth of wheat to an equivalent extent.
- Intervention effect CO2 enrichment increased tillering and yield components of wheat.
- Intervention effect Long-term exposure to O3 decreased the CO2 assimilation rate of wheat.
- Intervention effect O3 caused partial stomatal closure in wheat.
- Intervention effect O3 increased accumulation of fructan and starch in wheat leaves.
- Intervention effect O3 decreased shoot and root growth of wheat.
- Intervention effect O3 affected root growth more severely than shoot growth in wheat.
- Intervention effect Elevated CO2 enhanced the growth of O3-treated wheat.
- Intervention effect Elevated CO2 gave little additional protection of wheat against O3 damage.
- Association CO2 enrichment may make wheat more susceptible to O3 damage at the cellular level.
