|a Seed deterioration is a partially elucidated phenomenon that happen during the life of the seed. This review describes the processes that lead to seed deterioration, including loss of seed protection capacity against reactive oxygen species (ROS), damage to the plasma membrane, consumption of reserves, and damage to genetic material. A hypothesis of how seed deterioration occurs was also addressed; in this hypothesis, seed deterioration was divided into three phases. The first is the beginning of deterioration, with a slight reduction of vigor caused by the reactions of reducing sugars with antioxidant enzymes and genetic material. In the second, the cell shows oxidative damages, causing lipid peroxidation, which leads to the leaching of solutes, the formation of malondialdehyde, and, consequently, an increase in damages to genetic material. In the third phase, there is cell collapse with mitochondrial membrane deconstruction and a high accumulation of reactive oxygen species, malondialdehyde, and reducing sugars
