Evaluation the effect of rootstocks on postharvest berries quality of 'Flame Seedless' grapes

'Flame Seedless' (Vitis vinifera L.) is one of the most valuable grape cultivars in Egypt. Also, it is one of the earliest ripening red seedless cultivars which appeared in the Egyptian market. The current investigation was conducted during the two season 2013 and 2014 on 8 years old vines in the commercial orchard when soil was sandy. Vines were grafted on four rootstocks Freedom, Ruggeri, Paulson and Flame Seedless. Therefore, this study was conducted to evaluate the effects of different rootstocks on fruit quality attributes during shelf-life. The Paulson rootstock presented highly marketable under Egyptian conditions compared with other rootstocks as to physical and chemical quality characteristics. As the main conclusion, graft Flame Seedless vines onto Paulson rootstock to improved fruit quality and also to enhance economic crop in Egyptian market
