| Abstract | ||||
| Table grapes are facing postharvest problems such as weight loss, shattering, decay, stem browning, etc and they are major factors that restrict of the storage period and to distant markets. Therefore, this study aimed to find out suitable methods to solve the postharvest problems and improve the storage life of "Ruby seedless" grapes whether during cold storage or in marketing condition. This experiment was conducted during two successive seasons (2014-2015) to study the effect of dipping in salicylic acid at 4mM/l, paraffin oil and wrapping with polyethylene stretch on some physical and chemical properties of clusters and berries during storage life under cold storage at 5 °C in refrigerator with 85-90% R.H for 30 days or at 20+ 5°C to estimate as marketing condition for 10 days. Results proved that all treatments gave positive effect on storage life and maintain the quality of cluster for the longest period possible under different storage conditions compared with untreated fruits (control), by reduced both of shattering %, weight loss % and retention the juice content of berries as long as possible, increased TSS, prevent the reduction of acidity, enhanced the total anthocyanin in berry skin. As for the total phenol, of treated clusters with salicylic acid had the highest significant effect on increasing the total phenol in berries compared with the other treatments and control. | ||||
