Abstract : The early development of the exocarp and the endocarp of mango fruits were characterized, taking into account morphohistological changes. After fertilization the palisade cells of the ovary multiply in an anticlinal pattern. When the fruit grows to about 4-5 cm in length fundamental changes occur; in the endocarp, the anticlinal multiplication and cell expansion occurs in the daughter cells which tend 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 deposit 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 parenchymatous cells begins to accelerate and cells of the middle pulp double in size, cells near the endocarp multiply intensively in a complex pattern apparently like a patch of circular divisions.
