e0“The effects on photosynthesis caused by altered CO2 diffusion can be distinguished from those caused at the chloroplast level by evaluating the CO2 concentration inside the leaf.”

Other claims from this paper (4)
- Method / resource CO2 fixation rate can assess the effects of toxic chemicals on photosynthesis.
- Mechanism Stable or rising internal CO2 during declining photosynthesis indicates chloroplast inhibition.
- Mechanism Declining internal CO2 with declining photosynthesis may indicate slower diffusion into the leaf.
- Mechanism Stomatal closure is suggested as the probable cause of diffusion-related photosynthesis decline.
