Gil et al. (1996) reported that for the ‘Mollar’ cultivar grown in Spain, arils constituted 57–66%, while aril contentof ‘Jabal 1’, ‘Jabal 2’, Jabal 3’ and a wild cultivar grown in Omanranged from 50 to 67% (Al-Said et al., 2009). In six cultivars grown in Morocco, aril yield ranged between 53 and 61% (Martínez et al.,2012). High variability in aril yield between different cultivars andfruit of the same cultivar has prompted the need for the indus-try to develop techniques that can non-destructively visualize and quantify internal structures of the fruit.
