The changes in the carbohydrate content during the period of fruit bud differentiation (FBD) were stuoied diurnalry in buds which were expected to produce vegetative growth, reproductive growth and those which were expected to remain dorment The results indicated that the starch content old not vary during the different stages of FBD in the buds which were expected to flower. Decreased contents of reducing and non-reduc­ing sugars were observed in the buds during FBD but were high before the onset of FBD. The differentiated buds (post-FBD) had higher content of reducing and non-reducing sugars, when compared to scar buds (buds which were expected to produce vegetative growth). The changes in the carbohydrate levels in scar buds and buds clearly indicate that the processes of vegetative growth and flowering are associated with biochemical activity.
