Transpiration - Water Movement through Plants
Respiration and Transpiration - The Plant Cycle
Leaf photosynthesis was measured using the LI-6200 portablephotosynthesis system (LI-COR, Lincoln, Nebraska 68504, USA) on attachedleaves in the field between 10:00 a.m. and 2:00 p.m. (Beijing time) on sunnydays. Air temperature (Ta), leaf temperature (Tf), relative humidity (Rh), netphotosynthesis (Pn), stomatal conductance (Gs), intercellular CO2concentration (Ci), stomatal resistance (Rs), and stomatal conductance (Cs)were measured or calculated. Leaf gas exchange readings were taken byquadrants (i.e., readings were taken from the eastern, southern, western, andnorthern quadrants of each tree) to minimize any potential environmentalimpacts.

(However, plants generate daily variations in concentrations of oxygen and carbon dioxide through their photosynthetic and respiratory activities.) Thermal profiles at midday in corn fields at various stages of growth are shown in Figure 4.4, demonstrating the marked reduction in ground temperature due especially to shading.

were used, while just the middle layer of herbaceous leaves at the flowering stage was used in experiments.
A GFS 3000 high precision portable gas measuring system was used to measure the photosynthetic CO2 exchange and leaf transpiration under optimal photosynthesis conditions.
Chlorophyll content was measured spectrophotometrically
The undetached leaves were placed into a clip chamber with an artificial light source at constant temperature and humidity, and measured for 25-35 minutes.

The photosynthesis/transpiration compromise revisited
Although it seems as thoughwater loss is a serious, intractable problem for a plant, it is NOT.
