Mung bean seeds has been exposed to accelerated ageing(A.A) conditions( 45± 100% R.H.) for 2, 4, 8 and 14 days. Evaluation of biochemical changes were obtained by comparing accelerated aged seeds to un-aged seeds (control).The results were revealed many biochemical changes that have been occurred during accelerated ageing of seeds and leaves of field plants, such as: 1. A significant increase in malondialdehyde (MDA), as a result of membrane damage due to lipid peroxidation. 2. A significant increase in proline content of seeds exposed to A.A conditions compared to un-aged seeds. 3. A significant decrease in protein, catalase enzyme (CAT), glutathione (GSH) and ascorbate (AsA) in seed were exposed to A.A conditions. 4. No significant change of glutathione, ascorbate, proline, protein and chlorophyll content in leaves of filed plants of their seeds that already expposed to A.A conditions.
