This work had been done as a contribution to the study the processes of growth and development of Badea fruit (Passiflora quadrangularis L.). Fruit samples of different sizes were taken and treated by histological techniques and analyzed under microscope. Eight stage of development of diameter fruits were evaluated: 6; 10; 18; 22; 30; 40; 60 y 80 mm. Continues divisions in the external epidermis cells and parenchima on the three first stages were observed. Aditionally, the fruit originated from a triangular ovary, progresively pets a circular from. From the fourth stage, fruit ripenning initiates and the placenta starts to fill the locules and sarround the seed. At the eight stage the aril, which is originated from thickening of funiculus apical zone is observed. all the proeesses, which take place during the fruits growth produce their final form and establish the organoleptic caracteristics.
