The role of reactive oxygen in harvested fruits and vegetables during maturation and senescence and the influences which handled by several gas treatments

After harvest, the body's own active oxygen equilibrium system will gradually be destroyed of fruits and vegetables so that there will be a huge accumulation of O-2·, H2O2, and MDA, which eventually leading to peroxidation of cell membranes, damage of protein structure and DNA. Thus, in recent years, researchers have been working on the research of the reactive oxygen metabolism of postharvest fruits and vegetables.This paper reviewed the role of reactive oxygen in harvested fruits and vegetables during maturation and senescence and the influences which handled by NO, H2 S, O3and MAP after the harvest, in order to provide references for the future research.
