Abstract
To study the quality of litchi (litchi chinensis. Sonn) fruit as effected by exposure to sunlight on the tree, five cultivars viz; Purbi, Bedana, Bombai, Serai and Gola were collected from the orchard of Fruit and Vegetable Developernent Board (FVDB),D.I.Khan. Fruits of each cultivar were picked from exposed and unexposed portions of the trees and were subjected to physio-chernical analysis. All the parameters studied were significantly different at p = 0.05. The results indicated that exposed fruits were less acidic. rich in Vitamin C, total sugars and reducing sugars as well as soluble solids. The unexposed fruits were found heavier in weight. stone, peel and pulp along with more total acidity (%) and non-reducing sugars. Keywords: Litchi. litchi chinensis, sunlight, epicarp, pulp, total sugars.
