Figure 4
De-epoxidation index of V-cycle (a) and Fv/Fm variations (b) during incubation at 32°C in darkness. Control samples incubated in darkness at 17°C are represented with closed symbols. Treated samples are shown as open symbols. Each symbol represents the mean ± SE (n = 5). Asterisks show significant differences between control and treatment (P < 0.05).
