Color parameters in broccoli florets stored at 20 °C. (A) Luminosity (L*) and (B) Hue angle of broccoli florets treated with 50, 100, 200 and 500 µM of melatonin and stored in the dark at 20 °C for 0 and 7 days. Each bar represents the mean value ± standard error (n = 3) obtained for each concentration used. Asterisks indicate significant differences with the control of that day based on a Tukey HSD test with a significance level of p < 0.05. In (B), the Hue angle scale has been incorporated as a color guide.
