jmax_temperature_param_flat {PhotoGEA} | R Documentation |
Jmax-related temperature response parameters from Bernacchi et al.
Description
Parameters that describe a flat temperature response (in other words,
no dependence on temperature) for Jmax-related photosynthetic
parameters, intended to be passed to the
calculate_temperature_response
function.
Usage
jmax_temperature_param_flat
Format
List with 2 named elements that each represent a variable whose temperature-dependent value can be calculated using a polynomial equation:
-
alpha_j_norm
: The apparent quantum efficiency of electron transport (alpha_j
) normalized to its value at 25 degrees C. -
theta_j_norm
: The empirical curvature parameter normalized to its value at 25 degrees C.
In turn, each of these elements is a list with 3 named elements:
-
type
: the type of temperature response. -
coef
: the polynomial coefficients. -
units
: the units of the corresponding variable.
Source
Here, the polynomial coefficients (coef
) are all set to 1, speciying a
zeroth-order polynomial equal to 1, which means that the values will not
depend on temperature.
