Chemical changes occuITed during growth and development of ber fruit cultivars Urman and Kathaphal were. studied at Post-harvest Laboratory, Department of Horticulture at CCSHAU, Hisar. Starch content decreased progressively during the. initial stages of fruit development, but. thereafter no remarkable reduc.tion in starch content was found in both the cultIvars. Total phenols and total protems decreased progressIvely wIth the subsequent development of fruits of botlp the cultivars. Protein banding pattern at different stages of fruit development i. e. after fi-uit set, before ripening an4 ripening did not show any specific differences in polypeptide pattern in both the cultivars Urman and Kathaphal except band D having high intensity. The activity of enzymes amylase and protease increased progressively with the advip1cement of ripening in both the cuItivars except at last stage of maturity. However, polyphenol oxidase activity increased upto 5th of April after fruit set and then decreased at later stage of ripening in ber.
