In this applied mathematics sub-chapter, two different sections are presented: Notions in probabilities and Parameter estimation (for dynamic systems).

The objectives of these sections are practical and oriented to the development of plant growth models and their application in confrontation with experimental data.

Notions in probabilities are introduced in order to be able to build a stochastic growth model of the plant organogenesis.

Parameter functions are more related to plant functioning, such as organ sink functions and modelling of photosynthesis.

Parameter estimation is oriented to the identification of some hidden parameters of the model.
