Abstract
Carbon dioxide is an important raw material for the process of photosynthesis.
Therefore, it is logical to assume that CO2-effects upon crop productivity are primarily caused through enhanced rates of photosynthesis.
In the first paragraph are discussed some photosynthetic properties of leaves at a range of horticulturally interesting light intensities.
In the second paragraph the CO2-transport in and near the plant is compared with the transport in the glasshouse atmosphere.
The potential photosynthetic rate of a crop is approximated for various values of the physiological and external transport resistance.
Finally, the probable importance of non-photosynthetic CO2-effects upon crop growth and development is briefly indicated.
