A study was conducted to evaluate the physical and chemical changes occurring during the various stages of fruit growth and development of 12-year-old Ber (cv. Gola and Chhuhara) trees. The ber fruit had a growth pattern of double sigmoid type. Fruit size rapidly increased from fruit set to 30^th Nov. and comparatively slow from 30^th Nov. to 30^th Dec., there after it was increased upto 20^th March. The fruit size remained unchanged after 20th March. Shape index was higher in initial stage and decreased continuously during the growth. The changes in fruit weight were almost similar to that of fruit length or diameter. 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. Pulp stone ratio was a slow and gradually increased after fruit set, followed by a sharp increase. The total soluble solids were low in early stage and it increased very much during later stages of fruit development. The per cent acidity was gradually increased up to 15th Feb. in cultivar Gola and upto 1^st March in Chhuhara, respectively, and it declined thereafter. Ascorbic acid content gradually increased from fruit set to maturity.
