Abstract : A study was conducted to evaluate the physical and biochemical changes occurring during the various stages of fruit growth and development of 12-year-old mango (cv. Safdar Pasand) trees. Fruit samples were collected at 10 days interval from 20 days after fruit set until harvest maturity. The physical parameters and chemical composition of fruits were measured. The mango fruit had a growth pattern of simple sigmoid type. The changes in fruit weight and volume were almost similar to that of fruit length or diameter. Initially, fruit volume was more than that of fruit weight. The difference of fruit volume and weight was narrow up to 70 days after fruit set. Afterwards, the fruit weight was greater than that of the volume. The fruit weight increased with the advancement of maturity. The specific gravity of fruit showed a decreasing trend during the early stages and increased continuously until full fruit maturity. The moisture content of fruit decreased during the growth and development. The number of lenticels decreased with the advancement of maturity. The mango seed also showed a sigmoid growth. The rapid increase in length and diameter of seed was recorded up to 60 days after fruit set. A gradual increase in total soluble solids, total sugar and reducing sugar was observed, while acidity declined with the advancement of maturity. Maximum quality parameters were obtained in ripened fruits of 80 days after fruit set.
