Abstract

Our developing systems are growing plant organs, Plant organs grow symplastically, i.e., in a co- ordinated way. In our approach we treat the symplastic growth of a plant organ as an example of irreversible deformation (plastic strain). Specificity of the organ in comparison to elasto-plastic or elasto-viscous solids is expressed mainly in cell divisions. Symplastic growth leads to the concept of a growth tensor. Cell divisions occur in the principal planes of this tensor.
