GreenLab Functional aspects
-
GreenLab function modelling aspects are greattly inspired from process-based approaches.
However, GreenLab function modelling differs in terms of organ compartment definition, making use of structural temporal positions.
It also differs in the definition of organ sink strength.
It adapts crop biomass production modelling formalism to the single plant scale.
This section presents GreenLab's functional modelling principles.
-
The growth cycle is the unit thermal time period for which biomass production and allocation are evaluated
Biomass production follows the classic PbM Beer Lambert law, applied to the individual plant
Biomass is allocated to cohorts of organs defined by their appearance date and physiological age
Organs compete for a common biomass pool according their sink strength function, characterizing their phenology
The expression of biomass production, biomass allocation and plant and organ scales are mathematically explicit, leading to a set of equations describing the plant as a dynamic system.
Course Objectives
-
The aim of this course is to enable students to:
- Revisit the eco-physiological concepts involved in plant crop models
- Learn about GreenLab's functional simplification and assumptions
- Learn about the biomass production and biomass partitioning approach
- Understand the model's equations with its mean full parameters
