Am |
is the gross photosynthetic rate |
Rd |
dark respiration rate |
alpha |
is quantum yield at low light intensity |
theta |
is the convexity |
x |
is the PAR intensity of the leaf |
use ggplot2 geom_smooth to fit the calculate data, generally the fit method is loess, but it does not matter, as we just want to see these data overlap with the measured ones as much as possible.
