Abstract Low-temperature storage is convenient for postharvest preservation of peach fruit, but peach fruit is sensitive to cold damage, which lowers its quality. Nitric oxide (NO) has the potential to improve the bitter resistance of peach fruit. In this work, peach fruit was treated with 15 μmol L−1 NO and 5 μmol L−1 c-PTIO [2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxo-3-oxide], to study changes in mitochondrial fatty acids and expression of the C-repeat binding factor (CBF). The results showed that 15 μmol L−1 exogenous NO significantly maintained fruit quality, reduced peroxidation of mitochondrial fatty acids, increased the activities of the antioxidants superoxide dismutase (SOD), peroxidase (POD), catalase… More >
