Compartmentalization of decay in trees
Compartmentalization of decay in trees (CODIT) is a model developed by plant pathologist Alex Shigo to describe how after a tree is wounded, the resulting defects are compartmentalized. == Theoretical background == In keeping with the theory of spontaneous generation, in which living things can develop from non-living things, scientists traditionally believed that tree decay led to fungal growth.
