FARKLI HASAT SONRASI BAZI UYGULAMALARIN ORGANİK YETİŞTİRİLEN NAR MEYVELERİNİN DEPOLANABİLİRLİĞİNE ETKİLERİNİN ARAŞTIRILMASI

Abstract

The most effective way to increase the consumption of pomegranate fruits both in export and in the domestic market is to extend the storage period. In this regard, it is necessary to preserve the quality and prevent losses during storage. In this study, the effects of post-harvest Siega Fresh® Finish (SFF) and Siega Fresh® Citrus (SFC) treatments on organically grown 'Hicaznar' pomegranate fruits on fruit quality and losses during storage were determined. SFF applications of organically produced pomegranate fruits were applied with the ULV device, while SFC application was applied by spraying on the fruits with a hand sprayer at three different doses, 2, 3 and 6 liters/ton. Only water-treated fruits were accepted as control. After the application, the pomegranate fruits were pre-cooled with air, the modified atmosphere packages were closed, and stored at 6°C and 90% relative humidity for 120 days. Some measurements and analyzes were made after a 3-day shelf life of the samples removed from the warehouse at 30-day intervals. Siega Fresh® Finish and Siega Fresh® Citrus application at a dose of 6 l/ton limited the development of rot during the storage process of organically grown pomegranate fruits. However, the effects of the applications on the fruit quality parameters were limited. Siega Fresh® Finish preparation is recommended because of its ease of application and partially more effective in preventing caries development than Siega Fresh® Citrus preparation. The results showed that with the post-harvest Siega Fresh® Finish application, organically produced pomegranate fruits can be successfully stored for 90 days (until the first week of February).
