- Performance of Different Grape Cultivars for Rooting and Grafting
- Published at:An-Najah Univ. J. Res., Vol. 13 (1999) 1-8
Four local grape cultivars (Halawani, Beiruiti Zaini and Beituni) were bench grafted on four different grape rootstocks (B41, Paulsen, Rugerri and Richter). Two grafting methods were used: whip tongue and wedge grafting. The experiment was conducted for two successive seasons (1997 and 1998). All rootstock basis were treated with Indolebutyric- acid (IBA) at 8000 ppm in the form of powder. The results showed a great variability in the rooting ability of the different rootstocks with Paulsen rootstock which resulted in the higher rooting ability, while Rugerri and B41 resulted significantly in the lower rooting percentage in both seasons. The scion as well as the grafting method did not affect the rooting ability of the rootstocks. The rootstock scion combination showed high healing ability with a significant interaction between both graft partners. Rugerri and Richter resulted in the highest healing of grafts. The vegetative bud growth of the graft varied among the different scion cultivars but without any significant effect of grafting method or rootstocks in both seasons. Both Halawani and Beiruiti resulted in the higher vegetative growth during propagation.
