Fig. 5. — Time courses of sap flow velocity of taller stem (height 63 cm) and shorter stem (height 19 cm) plants as the wind speed suddenly increases from 0 m s⁻¹ to 6.0 m s⁻¹. The symbols are measured data and the solid and dashed lines are the predictions of Eqn (5). The time constant for the taller plant is T_c=28.8 min, and for the shorter plant is T_c=9.1 min.
