: "" Kyoho grape berry (Vitis vinifera, L. × V. labrusca L. cv. 'Kyoho') as test materials, (investigate) 10μmol / L (Methyl jasmonate, MeJA), methyl jasmonate treatment (MeJAtreatment) on post-harvest (postharvet, harvested) grape fruit during storage at 1 ℃ (storage) acid (phenol from acid,) content and antioxidant activity of antioxidant the activity, and from the perspective of phenylpropanoid metabolism (metabolism) analysisrelated mechanism (mechanism). results show, 10μmol / L of MeJA was processing can significantly inhibit the grape fruit storage period (inhibit) decay rate and drop-grain rate (berry abscission rate) of the rise, induced (induce) benzene, propane class metabolism (phenylaprapanoid metabolism)the key enzyme phenylalanine ammonia lyase (PAL), cinnamic acid hydroxylase (C4H) and chalcone synthase (CHS) activity rise and delay (delay) coumaric acyl-CoA ligase (4-CL) decline in activity, while a significant increase (promote) the fruits of the main phenolic acids (gallic acid, caffeic acid, protocatechuic acid, syringic acid and p-coumaric acid) and total phenol content and maintain (maintain) the DPPH radical scavengingrate (DPPH radicals, scavenge rate) and reducing power (reducing power). these results indicate that (suggest), can be through the regulation of grape berry phenylpropanoid metabolism enzymes activity, MeJA was effective (remarkably, markedly, effectively) induced fruitof phenolic acid synthesis and to maintain the antioxidant activity of fruit during storage, and ultimately improve the postharvest quality of food and nutrition (edible and nutritional quality).
