Abstract: Plant seed aging is a complex process, it’s a series of biochemical, physical and chemical reactions. It has been proven by several international groups that cytoplasm in seed is in state of Glass, and the Glass Transition Temperature is closely associated with seed aging, being influenced by biomolecules in seed. I has also been found that non-enzymatic Maillard and Amadori reactions can occur in very low dry seeds, and the accumulation of products of these reactions has been thought as the reason for seed aging. The reason for Maillard reaction causing seed aging probably are the products of Maillard reaction could reduce activities of antioxidant enzymes, modify structures and functions of protein and nucleic acid, and induce sugar hydrolysis.
