Postharvest fruits are still alive, and they will soften gradually duri ng storage. Fruit ripening and softening is highly regulated by a complicated de velopmental course, during which a series of physiological and biochemical chang es occur, including the degradation of cell wall, the change of the inclusion, t he velocity of respiration and other metabolic change. Research advances on frui t ripening and softening are reviewed in the article. The change of the content of enzymes and auxins that related to the fruit ripening and softening and their functions were introduced and the mechanism of fruit ripening and softening wa s discussed. The results show that the course of fruit ripening and softening a re influenced by many factors such as very kinds of enzymes and auxins. The acti vity of the enzymes and the function of the auxins were different in different k inds of fruits. The discussion on the mechanism of fruit ripening and softening will provide the theoretical foundations for the storage and freshness and proce ssing of fruit.
