Incorporation of water into the model

PPT Slide

Affected processes and intermediate variables

Application of information:Amount of light captured affects rose production

For any crop: The canopy’s rate of capturing light is a function of the amount of leaf material per unit ground area (Leaf Area Index)

What is Leaf Area Index (LAI)?

Application of the model to decision-making

Fraction of PAR at top

How to make the calculation:

Canopy psyn at various temperatures and LAI

Canopy Photosynthesis vs LAI at 3 temperatures
