Figure 6.

Growth-induced longitudinal tissue tension in a stalk of rhubarb. The stalk is modeled as a cylindrical tube with elastic volume elements and growing surface elements. With decreasing surface-to-volume growth ratios from ϑ^=1.000, to ϑ^=0.967, ϑ^=0.933, ϑ^=0.900, and ϑ^=0.867, from left to right, the tissue tension increases and induces a higher curvature when the stalk is cut in fourths. Red colors indicate compression, green and blue colors indicate tension.
