The aim of this study was to determine the graft performance and to follow the graft compatibility of Bornova Misketi, Trakya Ilkeren and Sultan 1 grape cultivars grafted on 5BB and 1103P rootstocks. Grafts were made by using omega technique. Following waxing, grafts were packed in plastic boxes filled up with fungicide humidified sawdust and chips (3:1) and were placed in callusing room (25°C, 85% relative humidity) for three weeks. Post callusing, grafts were evaluated for their callusing rate at graft union (0–4 scale), sprouting rate (%), rooting rate (%) and sapling yield (%). According to obtained data statistically significant differences were determined in all parameters except sprouting rate. Graft samples were taken each month for histological analysis during six months following callusing. No significant differences were observed among combinations in respect to histological development of graft unions. Callusing rate (3.73/5 BB–3.70/1103 P) and potted sapling yield (86.66/5 BB%–90.00/1103 P%) were the highest in Bornova Misketi among all combinations for two rootstocks.

This research was conducted to determine the effects of three different grafting periods (March 1, April 1 and May 1) and six grafting methods (tongue, splice, cleft grafting by hand and cleft, wedge, omega grafting by three different manual grafting tools) on graft success and plant growth in persimmon sapling production. The experiment was carried out in a randomized complete block design with three replications in Rize, Turkey during 2012–2013. The ‘Hachiya’ persimmon (Diospyros kaki L.) were used for grafting scions. Two-year old Diospyros lotus L. seedling were used for rootstocks. In conclusion, graft take percentages varied from 21.7 to 81.7% in 2012, from 10.0 to 73.3% in 2013. Sprouting percentages varied from 11.7 to 73.3% in 2012, from 5.0 to 68.3% in 2013. These parameters, tongue and wedge grafting (with tool) performed on April 1 gave the highest results in both years. Graft shoot lengths varied from 38.6 to 65.7 cm in 2012, from 38.3 to 61.5 cm in 2013. Graft shoot diameters varied from 5.3 to 8.3 mm in 2012, from 5.5 to 7.8 mm in 2013. These parameters, splice grafting performed on April 1 gave the highest results in both years. In generally among all parameters the best type of grafting was tongue and wedge (with tool) grafting. The omega grafting with manual grafting tool gave the lowest results in all parameters. Grafting period on April 1 gave the highest results, May 1 gave the lowest results in all parameters.
