摘　　要：以番茄为试材,通过50 cm跌落处理对其造成机械损伤后,随机分为两组分别用蒸馏水、8 mmol/L腐胺溶液(Putrescine,Put)浸泡处理,研究腐胺处理对机械伤果实感官品质、营养成分及抗氧化酶活性的影响。结果表明:与对照组相比,腐胺能保持机械伤番茄的感官品质、色度、硬度和VC含量,提升过氧化物酶(POD)和抗坏血酸过氧化物酶(APX)活性,并有效抑制可溶性固形物的降解和丙二醛(MDA)积累,延缓果实衰老。Mechanically damaged tomatoes by dropping from 50 cm height were randomly divided into two groups and immersed by distilled water and 8 mmol/L putrescine(Put) respectively to investigate the effect of Put treatment on sensory quality, nutrients and antioxidant enzyme activity. The results showed that, compared with the control group, Put treatment could maintain the sensory quality, chromaticity, firmness and VC content of mechanically damaged tomatoes, and enhance the activities of antioxidant enzymes such as peroxidase(POD) and aseorbateperoxidase(APX), and effectively inhibited the degradation of soluble solids and the accumulation of malondialdehyde(MDA), which suggested that Put treatment delay the tomato fruit senescence.
