Mechanical Stress Induces Remodeling of Vascular Networks in Growing Leaves
Fig 6
Veins in experiments undergo non-affine deformations.
(A) Colormap of the non-affinity index q of each areole, after 15 days of external stretching; in the case of an affine deformation q would be equal to one for all areoles; q > 1 (resp. q < 1) means that the areole grew more (resp. less) than its neighbors. (B) Histogram of the orientation of veins before and after stretching showing that veins reorient in the stretching direction. (C) Histogram of q in the stretched and unstretched regions.
