f.Aci: Photosynthesis model

In TESTgroup-BNL/LeafGasExchange: A package containing functions for fitting photosynthetic response curves, simulat leaf and canopy photosynthesis

Photosynthesis model

Description

Calculate the assimilation according to Farquhar equations. Contrary to f.A, this function uses inter-cellular CO2 and not ambient air CO2

Usage

f.Aci(PFD, ci, Tleaf, param = f.make.param())

Arguments

PFD	Photosynthetic light at the leaf surface in micro mol m-2 s-1.
ci	Intercellular CO2 concentration in ppm
Tleaf	Leaf temperature in Kelvin.
param	List of parameters, see f.make.param for details

Value

List of different variables: - A: Raw assimilation of the leaf in micromol.m-2.s-1. - Ac: Rubisco limitation assimilation of the leaf in micromol.m-2.s-1. - Aj: Electron transport rate assimilation of the leaf in micromol.m-2.s-1. - Ap: TPU rate of the leaf in micromol.m-2.s-1. - Ag: Gross assimilation in micromol.m-2.s-1.

Examples

ci=seq(40,1500,10)
plot(x=ci,y=f.Aci(PFD=2000,ci=ci,Tleaf=300,param=f.make.param())$A)
