The rigidity of a turgescent shoot is dependent on (among other factors) the resistance of the cortical tissues; if, by overstretching, these are permanently lengthened, the rigidity of the system is Fig. 24, Exp. 161.

A straight turgescent shoot is fixed firmly by means of a bored and split cork in a test-tube of water, T, figure 24, and at a point which should be marked by a streak of Indian ink, it is further supported oh a prism of wood, F, resting on a support /S. At the free end, the shoot bears a needle acting as an index /, and a loop of wire L, to.
