This experiment was carried out during the years 2009-2012 to investigate the effect of the interstock on growth ‘Kiet’ scion also their effect on ‘sukkary’ rootstock. The rootstock plants were grafted with scion ‘Hindi’, ‘Ewais’, ‘Seddik’ and ‘Kiet’ as the first grafting , after one year the second graft were done by ‘Kiet’ scion on the different interstock. The vegetative growth parameters as length cm, thickness mm, leaves number, leaf area cm2, fresh dry weight of shoots (g) and grafting success percentage were recorded. The results cleared that the rootstock length of ‘sukkary’ had the highest value (43.95 and 43.80 cm) with ‘Kiet’ and ‘Seddik’ scion respectively. The scion length was insignificant differences among ‘Hindi’, ‘Ewais’ and ‘Seddik’ where the lowest scion length was ‘Kiet’ 57.25cm. The rootstock and scion thickness were insignificant among all of them. The leaves number were ranged from 31.10 to 47.80 of ‘Hindi’ and ‘Kiet’ respectively and the leaf area was the highest of ‘Hindi’ 113.4 cm2 and the lowest one of ‘Kiet’ 45.04 cm2 .The data of second grafting, where the ‘Kiet’ scion length was the highest value of ‘Kiet’ scion 79.50 cm., also the ‘Kiet’ interstock and the ‘Kiet’ scion thickness were the highest values of ‘Kiet’ 1.20 and 1.12 cm respectively but it were insignificant values of ‘Hindi’ interstock 1.14 and 1.01 cm respectively. The ‘Kiet’ leaves number ranged from 23.8 to 44.30 of ‘Ewais’ and ‘Kiet’ interstock respectively. The ‘Kiet’ scion of ‘Hindi’ interstock had the highest significant values of shoots fresh and dry weight 214.4 and 102.1 g. respectively, while ‘Kiet’ interstock was the lowest significant values of shoots fresh and dry weight (67.90 and 30.27 g.) respectively. These results revealed that the ‘Kiet’ interstock had dwarf effect while ‘Hindi’ had activator followed by ‘Seddik’ then ‘Ewais’.
