摘　　要：以"富士"苹果为试材,研究了常温贮藏条件下NO(一氧化氮)减压(0.5个大气压,50.662 5 kPa)处理对果实采后生理的影响。结果表明:NO减压处理可延缓果实可溶性固形物的降低;显著抑制果实乙烯释放量,显著降低呼吸强度;减缓果肉硬度下降;显著延缓丙二醛(MDA)含量的升高,从而降低膜脂过氧化程度;提高了POD的活性,减少H2O2的积累。结果表明:适宜浓度NO处理可明显改善其贮藏品质,延缓衰老。Experiments were conducted to study effects of a decompression of nitric oxide （0.5 atmosphere, 50.662 5 kPa） for Fuji apple postharvest physiology of during the storage in normal temperature conditions. The results showed that the application of NO decreased the reduction of fruit soluble solids and firmness significantly; inhibit fruit ethylene production, decreased the respiratory intensity; slowed down the increase of MDA, there- by reducing the extent of lipid peroxidation; increased POD activity, educed the accumulation of H2O2.The results suggested that： the application of NO could significantly improve the storage quality and aging.
