Area of Science:

• Plant Physiology
• Biochemistry
• Mathematical Modeling

Background:

• Coupled leaf photosynthesis and stomatal conductance equations can produce complex, unpredictable iterative solutions.
• Analytical solutions offer greater certainty and facilitate in-depth sensitivity analyses.

Purpose of the Study:
