Abstract :
Purpose: Quality loss is high in pomegranate due to physiological disorders occurred during growth and developmental stages of fruit in main production areas in Iran. Research method: we evaluated the effects of preharvest fruit bagging time (July and August), and bag color (white and brown) on sunburn, cracking, anthocyanin content, and quality of pomegranate fruit. This experiment was carried out on eightyearold pomegranate trees cv. Shishe-Kab in an orchard located in Ferdows, South Khorasan province, Iran. Main findings: The results showed that the maximum (90%) and minimum (25%) sunburn percentage was observed in control (non-bagged fruits) and whitebagged fruits at August (WBA), respectively. Similarly, the highest percentage of cracking (65%) and the lowest (5%) was obtained in control and WBA, respectively. Nonbagged fruits showed the highest (23.61 mg^-1) anthocyanin, and the lowest rate (13.55 mg^-1) observed in brown-bagged fruit in July (BBJ). The brightness (L) of the peel color of brown-bagged fruit in August (BBA) was the highest while the lowest L value obtained in control and white-bagged fruits in July (WBJ). Bagging did not change the weight, volume, and pH of pomegranate juice. Interestingly, bagging in both white and brown bag effectively reduced fruit sunburn and cracking and decreased the total damaged fruits, particularly when fruits were bagged in August, as compared with non-bagged control. Research limitations: No limitations were founded. Originality/Value: The results suggest that proper pre-harvest bagging to improve the quality and reduce losses of pomegranate fruit cv. Shishe-Kab.
