Abstract : Abscisic acid at 10-6 M concentration enhanced ripening of mangoes. The cells in the pulp of the fruit were large and parenchymatous and lost their integrity due to cell wall hydrolysis at the ripe stage. They contained abundant polysaccharides, consisting mainly of starch, which was degraded during ripening. The chloroplasts were transformed to chromoplasts containing red or yellow carotenoid pigment. Abscisic acid treatment enhanced all of these processes. Mitochondria, on the other hand, retained their structural integrity throughout the ripening process in untreated and abscisic acid-treated mangoes.
