Abstract: Abstract: A cell-growth-based algorithm is presented based
on the biomechanics of plant cells in tissues to help explain the
typical differences in cellular architecture found between dif-
ferent pome fruit species, cultivars and tissues. The cell was
considered as a closed thin-walled structure, maintained in
tension by turgor pressure. The cell walls of adjacent cells
were modelled as parallel and linearly elastic elements, which
obeyed Hooke’s law. A Voronoi tessellation was used to
generate the initial topology of the cells. Cell expansion then
resulted from turgor pressure acting on the yielding cell wall
material. To find the sequence positions of each vertex of the
cell walls, and thus, the shape of the cells with time, a system
of differential equations for the positions and velocities of
each vertex were established and solved using a Runge–Kutta
fourth and fifth order (ODE45) method. The model was used
to generate realistic 2D fruit tissue structures composed of
cells of random shapes and sizes, cell walls and intercellular
spaces. Comparison was made with fruit tissue micrographs.
The virtual tissues can be used for numerical simulation of
heat and mass transfer phenomena or mechanical deformation
during controlled atmosphere storage of fresh pome fruit.
