Abstract
A method for dynamically simulating plant growth using cosine and sine functions is presented.
The functions are described both in the derivative and integrated form.
In the study, the integrated model was fitted to growth data from previously published studies.
The model gave a good fit to data of leaf unfolding in Codiaeum grown in climate chambers, while the fit was not as good for shoot elongation in Quercus. This may partly be due to the fact that the oak plants were not grown under controlled climate conditions.
The advantages and disadvantages with using this type of model are discussed, together with the mathematical linkage between growth and development.
