Abstract : Detached fruits of mango cv. Bangalora were collected from the experimental orchard in Tamil Nadu, India. The fruit had 2 sides, i.e. sunny and shady sides. One side of the fruit, usually the base, which was nearer to the stalk, was exposed to the sunlight and that part of the fruit alone was yellowish orange. This was called the sunny side, while the rest of the fruit was greenish and it was called the shady side. Pigment studies were conducted using the epicarp of the tissues the determine the chlorophyll, carotenoid, xanthophyll and anthocyanin contents. The chlorophyll content was higher on the shady side of the fruit when compared to the sunny side. The content of carotenes, xanthophylls and anthocyanins increased both on the sunny and shady sides of the epicarp during the course of ripening. The sunny side had more carotenes, xanthophylls and anthocyanins than the shady side. Among the 3, the carotene content was always higher than the others.
