The canopy’s rate of capture and use of light is related to the amount of leaf material per unit ground area (=Leaf Area Index) So what is this optimum LAI level? What happens to light in rose canopies? Light in Rose canopies Light in Rose canopies Fraction of PAR at top Fraction of PAR at top Rose Canopy Photosynthesis Analysis in relation to leaf area index How to make the calculation: How to make the calculation: How to make the calculation: Canopy psyn at various temperatures and LAI Canopy Photosynthesis vs LAI at 3 temperatures We don’t yet know the optimal LAI. LAI=1.7 LAI=2.8 LAI=3.1 LAI=4.2 Conclusions Conclusions PPT Slide |
