Jmax-related temperature response parameters from Bernacchi et al.
jmax_temperature_param_bernacchi.RdParameters describing the temperature response of Jmax-related photosynthetic
parameters, intended to be passed to the
calculate_temperature_response function.
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
Polynomial coefficients were obtained from Bernacchi et al. (2003).
Here, we use the values determined from plants grown at 25 degrees C
(Table 2). The coefficients given in the paper are used to calculate the
values of alpha_j and theta_j at leaf temperature. Here we
normalize by the values of alpha_j and theta_j at 25 degrees C,
which are 0.6895 and 0.97875, respectively.
