Fig. 2

Non-climacteric melon fruit of a ‘Yellow’ commercial genotype of four development stages and its colour characteristics. From left to right there are 10 DAP, 20 DAP, 30 DAP and 40 DAP (a). In (b) L* (brightness) of peel fruit increases from 10 to 20 DAP and declines in 30 DAP and remains constant until 40 DAP. In (c) the coordinates on the a* axis increase during the maturation process in peel and pulp colour, representing the trend change from green to red. In (d) coordinates on the b * axis increase during maturation for peel colour, demonstrating the shift from blue to yellow coloration, the opposite profile was found for pulp colour. In (e) Hue angle (H°) decreased throughout ripening, corroborating with Kasim and Kasim (2014)
