Other claims from this paper (5)
- Association Fibre direction in a growing organ can be correlated with the maximal stress direction and with the direction orthogonal to the maximal strain direction.
- Method / resource The orthogonal-to-maximal-strain model led to an unstable situation where fibres reorient longitudinally.
- Method / resource A stress-based feedback on fibre directions reproduced the main features of in vivo cellulose fibre directions, deformations and material properties in the shoot.
- Method / resource The finite element shell model and the simpler triangular biquadratic springs approach gave equally adequate descriptions of epidermal cell mechanics.
- Observation The model created radially distinct regions in the shoot, with slow isotropic expansion in the central zone and faster radial expansion at the periphery.
