SOME PHYSIOLOGICAL ASPECTS OF CO2-APPLICATION IN GLASSHOUSE CULTURE |
| Author: | P. Gaastra |
| 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. Effect of CO/SB2/BS upon photosynthesis of single eaves. | |
