Abstract: The study aims to investigate the impact of the new fungicide dimethyl fumarate (DMF) on fruit storage quality of postharvest Hanzhong citrus, and determine the antisepsis effect of DMF on citrus. The author analyzed and measured the weightlessness rate, respiration intensity, the change of soluble total sugar and Vc content of citrus fruits in normal temperature storage treated by DMF. The results showed that the respiration intensity and weightlessness rate of citrus fruit treated by DMF within 156 days of storage were significantly lower than that of the control group; soluble sugar content and Vc content were greater than that of the control group. In conclusion, DMF treatment was effective in citrus preservation, it could delay the decline of the total soluble sugar and Vc content of the fruit, effectively restrain the respiration intensity rise and improve the storage quality of citrus.
