CO2 enrichment and
increasing light intensity
till a threshold level,
enhance growth and
water use efficiency
of lettuce plants in
controlled environment.
Climate Dynamics 44:
3469-3479.
"It has long been recognized that rising atmospheric CO2 concentrations are enhancing plant growth across the world.
... much remains to be learned about the interaction of elevated CO2 and other key factors contributing to plant growth.
"Elevated level of CO2 and increased light intensity also positively impacted lettuce leaf area and plant water use efficiency (WUE) ... it was "two times higher" at the two highest CO2 concentrations (1200 and 1600 ppm) compared to ambient (400 ppm)
... Esmaili et al. conclude "increasing light intensity and CO2 concentration resulted in better growth performance in lettuce plants."
... within each light intensity treatment, elevated CO2 raised the lettuce dry weight from 25% to 148%."
