Abstract
Cell number and size contribute leaf shape. It would enable us to answer the diverse of leaf shape if we could estimate spacio-temporal activities of cell division and growth through leaf development. However, they have not because of their difficulty of quantifications. Instead of this approach, we have been attempting to develop a simulation model.
Volonoi-diagrams deduced from distribution of palisade cells were same as real cell shape in the early stage of development. This result indicates that pushing force is balanced among cells. We designed a model that cell mobility is derived from growth of itself and surrounding cells and that cell shape is determined by distribution of neighbors. In the last meeting, we presented a behavior of cell objects that divided, expanded, relocated, and changed their shape. This simulator has been improved to regulate two dimensionally. In this presentation, parameter effects on leaf shape will be introduced.
