Abstract: The need for a year round supply of fruits with minimal loss of quality attributes calls for optimal handling and storage conditions. Fruit tissues are very heterogeneous at the microscale and the cellular architecture determines to a large extent the behaviour and development of the fruit. Therefore, understanding of the development and the changes of the microstructure of fruits will be an important step to help explain and optimize fruit quality during production and storage.

A tissue growth algorithm is being developed using the biomechanics of plant cells in tissues. From mechanical point of view, the cell can be seen as a closed thin walled structure, maintained in tension by turgor pressure. The cell walls of adjacent cells are modeled as parallel and linearly elastic elements (springs). The mechanism of cell expansion is then generally believed to result from the driving force, turgor pressure, acting on a yielding cell wall material, where both of these factors are ultimately controlled by the plant metabolic activity. The model is implemented in the Matlab programming environment combing Voronoi tessellation and mechanics and will be used to generate realistic fruit tissue structures composed of cells of random shapes and sizes, cell walls and intercellular spaces. Such virtual tissues can then be applied to study tissue mechanics and exchange processes of important metabolites.
