skin colour (20 fruit per replicate) was also recorded from the four
positions along the equatorial regions of each fruit in Commission
Internationale deL’Eclariage units using a HunterLab ColourFlex
45◦/0◦ Spectrophotometer (HunterLab ColorFlex, Hunter Associates
Inc, Reston, VA). The CIE L* a* b* (L*, lightness coordinate;
a*, red/green coordinate; b*, yellow/blue coordinate) were determined,
