Abstract

To explore the effect of different treatments on the cold damage of nectarine fruit, this experiment took ‘Shuguang’ nectarine as the test material, using methyl jasmonate (MeJA) ethylene absorber (EA) and MeJA + EA were used, and stored under temperature maintenance (0±1) ℃ and humidity of 90%-95% for 49 days.The relevant physiological indicators of the fruit were determined every 7 day.The results showed that compared with the control group, all three treatments could effectively delay the softening process of nectarine, delay the occurrence of respiratory peak, reduce the occurrence of cold damage, and increase the content of soluble solids, among which the MeJA + EA treatment had the best effect.MeJA + EA treatment significantly enhanced the phenylalanine ammonia lyase, a key enzyme in the phenylpropane pathway in peach fruit (PAL), cassia bark-acid-4-hydroxylase (C4H), and 4-coumarate Coenzyme A ligase (4CL) (P<0.05), and effectively inhibited the polyphenol oxidase (PPO) activity, promoted the accumulation of flavonoids and total phenols in fruits, and delayed the increase of lignin content, the cold hazard index was only 5.98% at day 49, The ability to resist cold damage was significantly higher than that of EA and MeJA treatment alone.The results can provided technical reference and theoretical basis for improving the storage and preservation effect of cold-sensitive fruit.

Key words： nectarine; cold damage; methyl jasmonate; ethylene absorbent; storage quality
