摘要： Nitrous oxide (N2O) was investigated for the potential use on inhibiting the postharvest decay of the grape. In this study, 50 mu L L-1 N2O gas was used for fumigating the 'Manage' grape which was used as the test material at room temperature for 6 h. Results indicated that N2O had no direct effect on the Botrytis cinerea inhibition. But N2O can promote the accumulation of total phenolic, flavonoids and lignin, as well as increase the activities of phenylalanine ammonia-lyase (PAL), cinnamate-4-hydroxylase (C4H), and 4-coumarate CoA ligase (4CL), which were the key enzymes in the metabolism of phenylpropanol. N2O also induced PAL family genes expression in a short time at the molecular level. Thereby the N2O significantly reduced the lesion diameter and incidence of the grape fruit inoculated with Botrytis cinerea. These results suggested that N2O participated in enhancement of disease resistance by improving the phenylpropanoid pathway metabolism of the grape fruit and it could be a promising strategy to suppress postharvest disease.
