| Abstract | ||
| Peach is a climacteric fruit suffering from rapid over-ripening and softening as well as quality deterioration after harvesting as a result having short storage period and shelf life. Therefore, the objective of this study was to investigate the effectiveness of preharvest spray applications of 5 mM oxalic acid (OA) and 2% calcium nitrate (CaNi) on quality attributes of peach fruit cv. Swelling during 30 days of cold storage at 0±1ºC and 90-95% RH. The results showed that preharvest treatments of fruit with 5 mM OA recorded the significantly highest marketable percentage and visual appearance score, restricted the increase in total soluble solids/titratable acidity ratio and was more effective in maintaining the maximum content of ascorbic acid followed by 2% CaNi as compared to control. Therefore, it could be recommended to use OA at 5 mM and CaNi at 2% as safe preharvest treatments to maintain quality attributes of 'Swelling' peach fruits during cold storage. | ||
