Figure 3
De-epoxidation index of V-cycle and Fv/Fm variations during dark-dehydration after light or darkness pre-treatment. In (a) it is shown a fluorescence imaging of thalli before (left) and after dehydration (right). Before dehydration, the right branch of each thallus had been exposed to sun, and the left one had been maintained in darkness. The de-epoxidation index of the V-cycle (b) and Fv/Fm (c) are shown before (t0) and after dark-dehydration (Dh) of pre-darkened (closed bars) and pre-illuminated samples (open bars). Each bar represents the mean ± SE (n = 5). Letters above bars indicate significant differences among treatments (P < 0.05).
