| Abstract | ||
| This research was carried out for two successive seasons (2022 and 2023) in a private orchard located at Assiut Governorate, Egypt, to evaluate the effectiveness of propolis extract and sodium thiosulfate in maintaining the quality attributes of Saidy date palm fruits during storage. The date palms were 17 years old, grown in a sandy soil, spaced at 8 * 8 meters apart, and irrigated by the drip system. At the end of August, five pre-harvest treatments of date bunches were sprayed as follows: two concentrations of propolis (3% and 5%) and two concentrations of sodium thiosulfate (0.5% and 1%), in addition to the control treatment (spraying with water). Date bunches were stored at ambient conditions (21 ± 7°C and 60 – 70% RH) for 75 days, and the fruit quality was evaluated every 15 days. The results demonstrated that all quality analyses showed that all applied treatments outperformed the control. Sodium thiosulfate at 1% and propolis extract at 5% were more effective than various treatments Saidy date fruits last longer by lowering the number of fungi, slowing down physiological and weight loss as well as decay. It is delaying changes in total soluble solids, total acidity, as well as total sugars during 75 days of storage at room temperature (21 ± 7°C and 60 – 70% RH) in both seasons. | ||
