Fig. 7.

The effect of light intensity on the kinetics of water movement on the same vessel in the leaf used in Fig. 6, which experienced repeated refilling cycles in the dark and had achieved a constant rate of movement of the meniscus. Light intensities of 0, 30, 60 and 140 µmol m⁻² s⁻¹ were applied during each rehydration cycle. The light intensity was reduced again to 0 µmol m⁻² s⁻¹ in the final cycle of refilling. Numbers 1–5 indicate the order of the refilling cycles.
