Developmental stages of mango fruit have not been quite studied. The purpose of this research is to characterise the early development of the exocarp and the endocarp of mango fruit taking into account morphohistological changes. Mango's flowers and fruits were collected in different developmental stages for optical and SEM microscopy observations. After fertilisation the palisade cells of the ovary multiply in on anticline pattern. When fruit grows to about 4–5 cm in length fundamental changes occur; in the endocarp, the anticline multiplication and cell expansion occurs in the daughter cells whose size and form with tendencies towards an isodiametric shape, the result is an undulating pattern where crests correspond to the largest cells and the valleys to the smallest cells. SEM images show a characteristic cuticle deposition present in all subsequent stages of development until fruit ripening. Endocarp cells divide and daughter isodiametric cells become a meristematic inner epidermal tissue. Mesocarp expansion of parechymatous cells begins to accelerate and cells of the middle pulp double in size, cells near de endocarp multiply intensively in a complex pattern apparently like a patch of circular divisions. Further research is required to describe mango fruit development until maturity
