Enhancement of chilling tolerance has been observed in fruits treated with oxalic acid (OA). To learn how OA may play a role in modulating chilling injury in apricot, the fruit were treated with OA (5 mM) and stored at 2 ± 1 °C for five weeks. OA treatment significantly inhibited chilling injury, electrolyte leakage and accumulation of hydrogen peroxide and malondialdehyde in apricot fruit. Sorbitol, sucrose, fructose and glucose were the major soluble sugars in the fruit.
