jmax_temperature_param_flat: Jmax-related temperature response parameters from Bernacchi...

In PhotoGEA: Photosynthetic Gas Exchange Analysis

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.
