The Effects Of Two Different Grafting Methods On Some Graft Properties Of The Graft Combinations Consisted Of The Cuttings Of Sultani Seedless Grape Variety And Different American Rootstocks

Scions of Sultani Seedless (S.S.) grapevine variety and cuttings of three vine rootstocks (1103P, 41B and Ramsey) were used in the study. The cuttings were grafted with two different grafting methods (omega and chip-budding). Graft successes of grafting methods and rootstocks in fusion (callusing room) and adaptation rooms were evaluated. In respect of callus level, 1103P rootstock and 1103P rootstock omega grafted cuttings are successful. The 1103P omega grafted cuttings had the highest amount in respect of callus on rootsto ck side and total callus; as the highest amount callus on scion side were weighed at 41B chip-budding grafted cuttings. 1103P/S.S. omega grafted cuttings had the highest percentage of sprouted grafted cuttings (42nd day, 100%), average of shoot length (42nd day, 19.5 cm), percentage of rooted grafted cuttings (42nd day, 23%), average of root number (42nd day, 35 roots), average of root length (42nd day, 3.8 cm) and the lowest percentage of grafted cuttings having decay on their bottom (10%). Also, chip-budding grafted cuttings of the same scion/rootstock graft combination were second about percentage of sprouted grafted cuttings (42ndday, 46 %), average of shoot length (42ndday, 11 cm), percentage of rooted grafted cuttings (42ndday, 17%), average of root numbers (42ndday, 21 roots) and average of root length (42ndday, 1.9 cm). One-week adaptation phase after four-week fusion phase is considered appropriate, because there were regression in general for the evaluated criteria of 35 days after grafting. Moreover, omega graft method for 1103P and 41B and chip-budding graft method for Ramsey with Sultani Seedless grafting combination were suggestible.
