Abstract
Research on Determination of Best Grafting Method and Best Graftage Time for Raising Grafted Young Walnut Trees During Summer Period in Tokat City Center
In this study, the purpose was the to determine best graft method and best graft time for grafted young walnut trees during summer period in Tokat city center. Walnut seeds were planted to field in november, 2002. At the vegetation period of year 2003, young walnuts trees, ready to graftage between july and september were grafted. Using Patch budding, Cleft grafting, T budding and Whip grafting methods. The best grafttage method was obtained by using Patch budding (%72,08). Beside Patch budding, T budding was also found succesful (%64,87). Because of unmature of shoots and budding, the success of Cleft graftting was (%48,50) and Whip grafting was %39,87. It s found that, the best time for late summer grafts was between June 20 and 30, and between August 1 and 10. It is concluded that, irrigation, one week before the graftage, made graftage easear. Avarege temperature 20,6 ºC in July and 21,9 ºC in August affected the ratio of bud-take direckly. The best result of proteching grafted young walnut trees from cold was obtained using izocam procetion method (%63,78). Highest survival ratio was found using Patch budding method (%84,78). Lowest survival ratio was cacluded for , Cleft graftting (% 33,5).
