The present paper is an investigation of the impacts of hexanal and Pelargonium. essential oil (PEO)-Cucurbita pepo oil (CPO) on the quality and storability of grape cv. Bidaneh Sefid, conducted in Bu-Ali Sina University. The treatments include 1) dry controls (untreated fruits), 2) wet controls (treated fruits with 0.02% of Ethanol as solvent, used for preparation of the other treatments, 3) hexanal, 4) EFF, and 5) combination of PEO and CPO. After the treatments, the fruits have been stored at 0±1°C and 65-60% RH. At the beginning of the storage, and every 15 days, some parameters have been evaluated, with the results showing that none of the treatments have had any significant effect on titratable acidity, pH, total phenol content, and fruit quality. Also, it is found that the lowest increase in soluble solids (35.59%) has belonged to EFF treatment, differing significantly from control untreated fruits. Control fruits with the highest rate of rot (3.5 score), weight loss (9.3%), and the lowest firmness (201.3 N mm -2 ) are lower in terms of quality than other treated fruits. Hexanal treatment has been more successful to maintain color indices a* and L* in comparison with other treatments. In general, the most effective treatment for preservation of postharvest attributes of grape has been EFF treatment, having considerable effects on reduction of weight loss, activity of the polyphenol oxidase enzyme, fruit rot, and color change of rakis, which seems that good synergistic effects of hexanal treatment, PEO, and CPO has maintained quality of grapevine fruits cv. Bidaneh Sefid during the two months of storage. [ABSTRACT FROM AUTHOR]
