Abstract

The effects of hexanal and Pelargonium. essential oil (PEO)-Cucurbita pepo oil (CPO) on the quality and storability of grape cv. Bidaneh Sefid during cold storage was investigated. The treatments included 1) controls as untreated fruuits, 2) Wet controls (treated fruits with solvent (0.02% 0f Ethanol) that was used in preparation of treatments), 3) hexanal, 4) EFF and 5) combination of PEO and CPO. After treatments, the fruits were stored at 0 ± 1° C and 65-60% RH. At the beginning of the storage, and every 15 days, some parameters were evaluated. The results showed that none of treatments had not significant effect on titratable acidity, pH, total phenol content and fruit quality. The lowest increase in soluble solids (35.59 %) was observed in EFF treatment, which had a significant difference with control untreated fruits. Control fruits with the highest rate of rot (3.5 score) and weight loss (9.3 %) and the lowest firmness (201.3 N mm-2) had less quality than other treated fruits. Hexanal treatment was more successful in maintaining color indices a* and L* in comparison with other treatments. In general, the most effective treatment in preservation postharvest attributes of grape was EFF treatment with significant effects in reducing weight loss, activity of the polyphenol oxidase enzyme, fruits 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 2 months of storage.
