lightresponse: Non-rectangular hyperbola

In YplantQMC: Plant architectural analysis with Yplant and QuasiMC.

Description

A simple light response function that predicts leaf photosynthesis from absorbed PAR.

Usage

lightresponse(PAR, Amax, phi, theta, Rd, ...)

Arguments

PAR	Photosynthetically active radiation (mu mol m-2 s-1)
Amax	Maximum assimilation rate (the asymptote) (mu mol m-2 s-1)
phi	Quantum yield (slope at PAR = 0) (mol mol-1)
theta	Shape of light response curve (0 = rectangular hyperbola, 1 = 'Blackman' response).
Rd	Dark respiration (**positive** value).
...	Further arguments are ignored.

Value

Returns a dataframe with :

A

Net assimilation rate (mu mol m-2 s-1)
