The present study endeavours to describe as to how far outward manifestations of vegetative malformation are supported by internal metabolic process in the shoots of two varieties of mango viz. Bombay Green (highly susceptible) and Bhadauran (free from malformation). Observed data indicated that like healthy shoots malformed shoots also showed high C/N ratio which is conducive to the synthesis of floral stimulus, resulting in initiation and further development of flowers and fruits. Malformed shoots although had differentiated fruiting buds like healthy ones they never gave normal flowers and fruits. It was concluded that metabolites translocated from the leaves to the stem were, somehow, blocked up in the malformed shoots and were not utilized for the further development of flowers and fruits. Two important possibilities have been suggested to explain this peculiar behaviour of malformed shoots.
