| Abstract | ||||
| This study was conducted during two seasons (2013 and 2014) to assess three rootstocks effect on growth, yield and fruit quality in table grape (Vitisvinifera L.) cv. Red Globe. Six years old vines of Red Globe grape grafted on three commercially available rootstocks namely Freedom, Richter and Salt Creek plus a control treatment (own-rooted vines) were evaluated under Ismailiaregion conditions of eastern Egypt.Vegetative measurements (shoot growth, number of leaves /shoot and leaf area), yield /vine and berry characteristics (weight, size, TSS, total acidity, TSS/acid ratio and anthocyanins content) were recorded.The results revealed thatthe highest values of shoot growth were recorded when Red Globe was grafted on Freedom rootstock while the lowest values were recorded by Richter rootstock. Salt Creek rootstock recorded the highest valuesof leaf area compared to the other rootstocks which were statistically equal. The results showed also that the studied rootstocks had no impact on leaves number per shoot, vine yield andberry acidity. Freedom and Salt Creek rootstocks increased berry weight and size compared to Richter rootstock and control vines. Freedom and Richter rootstocksenhanced the contents of TSS and anthocyanins compared to Salt Creek rootstock and own-rooted vines. The results suggested that Freedom and Richter rootstocks are appropriate to improve coloring and sugars in Red Globe grapes while all rootstocks and own-rooted vines were equal in regard to leaves number per shoot, vine yield and berry acidity | ||||
