Optimization model of the stomatal regulation in C{sub 3} plants: 2. Stomatal response to ambient CO{sub 2} concentration
- Timiryazev Institute of Plant Physiology, Moscow (Russian Federation)
The optimization model of photosynthesis predicts CO{sub 2} concentration in the intercellular spaces (c{sub i}) to be dependent on environmental factors, including ambient CO{sub 2} concentration (c{sub a}). The predicted linear c{sub i} dependency on c{sub a}, which was inferred from a more general optimization statement, can be confirmed by literature data. In most cases, the model specifies well-known phenomenological dependency, i.e., the constancy of the c{sub i}/c{sub a} ratio. Upon simultaneous changes in other environmental factors, the model also predicts the changes in the c{sub i}(c{sub a}) dependency. The optimization statement was fulfilled to the same or higher extent, in which the basic input assumption was satisfied. It is concluded that the optimization approach is able to explain all data available on the stomatal responses to changes in ambient CO{sub 2} concentration. 22 refs., 4 figs., 2 tabs.
