====== Introduction to growth modelling: sink-source coupling ======

**Time**      : 11:45 - 12:30\\
**Presenter** : Gerhard Buck-Sorlin\\

Coupling of source (photosynthesis) and sink (growth, respiration,...) functions
===== =====

At the example of a sunflower model developed as a teaching tool at the Bachelor level, this session will briefly introduce the coupling of the previously introduced photosynthesis model with a simple allocation model based on the central pool concept and redistribution of assimilates according to the relative sink strength method introduced by Leo Marcelis. 
You can find the presentation {{:workshops:summer_school_25:03_tuesday:sourcesink.pdf|here}}, the sunflower model is available for download {{:workshops:summer_school_25:03_tuesday:sunflower.gsz|here}}, and the standalone photosynthesis model by Kim and Lieth is available {{:workshops:summer_school_25:03_tuesday:klps.gsz|here}}

Note that this is a preliminary version in which the actual growth rate is not yet fully functional. A more stable version will be provided soon (...hopefully!).
