The effects of low temperature conditioning (LTC) on the storage quality and postharvest physiology of the fruits of wampee ‘Wuhe’ (Clausena lansium L.) were studied. The fruits were treated with LTC I (12 ℃, 4 d), LTC II (8 ℃, 4 d) and LTC III (12 ℃, 2 d to 8 ℃, 2 d) and then stored at (3.0±0.5)℃ to investigate the effects on storage quality and postharvest physiology. Compared with the control, low temperature conditioning treatment delayed the browning of the fruits, improved total soluble solids (TSS) and vitamin C content, and inhibited the accumulation of malondialdehyde (MDA) content, maintained higher activities of superoxide dismutase (SOD) and phenylalanine ammonia lyase (PAL) activity, and lower activities of peroxidase (POD) and polyphenol oxidase (PPO) activity. Moreover, high total phenol content and antioxidat activity, high total phenolic and flavonoid content were maintained. Thereby the senescence of the fruits was delayed, and it is beneficial to reduce the browning of the fruits and improve the storage quality. In conclusion, LTC II treatment exhibited the best effect.
