Possible Predisposition to Injury. Stomatal behavior may be an important determinant of the amount of suppression of photosynthesis and resultant visible damage. Measurements of temperature, vapor pressure gradient, and total oxidant continuously during July and August in the conifer forest indicate that the maximum oxidant concentration occurs between 1600 and 1900 PST when both vapor pressure gradient and temperature are decreasing rapidly (7) in other words, the oxidant arrives with the cool, moist, marine air. 

As we have indicated, stomatal conductance has a greater influence on transpiration (Section 8.2G) than on photosynthesis (Section 8.4E), for which both gas-phase and liquid-phase conductances must be considered. For instance, transpiration increases more rapidly than photosynthesis with increases in gj so WUE then decreases (Eq. 8-39). Thus we need specific criteria to predict optimal stomatal behavior. Specifically, to maximize WUE, stomatal opening must be synchronized with the capability for CO2 fixation. As indicated above (Section 8.IB), stomatal opening can be regulated by the CO2 level in the intercellular air spaces, a decrease in caused by photosynthesis leading to an increase in, which then lets more...

By far the most interesting and significant feature of CAM plant stomatal behavior is that they may open at night and close during the day. 

Similar to the CO2 exchange pattern (see Chap. 5.1.2), any given plant may show variations in the basic pattern of stomatal behavior mainly in response to environmental factors (see Chap. 5.3.4). 

The question of CAM plant physiology in situ in natural habitats has recently been studied and increasingly attracts attention. Typical features of CAM plants, such as gas exchange, acid fluctuation, and stomatal behavior, have been measured continuously in the field during day/night cycles and seasonally. Also, isotope composition (5 C value) (see Chap. 3.3) has been determined in samples... 

What is the optimal behavior of stomata over the course of a day WUE (Eq. 8.39) is maximized by minimal stomatal opening because transpiration is decreased more than photosynthesis by partial stomatal closure that is, changes proportionally more than does 7c02 as changes (Fig. 8-23 also Section 8.4E). However, minimal stomatal opening can lead to very little net CO2 uptake. Thus a more pertinent consideration might be the maximal amount of CO2 that can be taken up for a certain amount of water transpired. The amount of water lost depends on the plant condition and environmental factors and should be considered over the course of a whole day.
