Abstract

The study determines the graft take of walnut in Ordu province located in the East Black Sea Region. Grafting studies were carried out in nursery conditions in late August from 1993 to 2000. During these years, a total of 87 264 applied grafts were evaluated by using patch-grafting method. The graft take varied from 29% to 64 % depending on years. Relations between the graft take and climate conditions were also considered. Graft take under nursery conditions was affected by especially relative moisture (%) in addition to the mean and maximum temperature (°C) in August and September months.
