The effects of different concentrations of CTS treatment on the color changes of the peel of postharvest longan. L* (lightness) value (A), a* (greenness) (positive values) (B), b* (yellowness) (C), h (hue angle) (positive values) (D), color index (positive values) (E), and browning index (F). Error bars represent SD (n = 4). Bars with a different letter within a sampling date are significantly different (P < 0.05).
