Studies on the Compatibility of Grafting on Pistachio Variety of Ashouri with its Rootstocks P. Vera, P. Atlantica and P. Khinjuk

The research studied the compatibility of grafting on the pistachio variety of Ashouri with three rootstocks (P. vera, P. Atlantica and P. Khinjuk). This research was implemented in the nursery of the agricultural department in Hama. The seedling rootstocks were budded in plastic bags at the beginning of June by T-budding. The results demonstrated that the variety of Ashouri which budded on the Ashouri and P. Khinjuk rootstocks excelled at the p. Atlantica rootstocks, The best average of succeeded graft of Ashouri variety budded on the Ashouri and P. Khinjuk rootstocks reached (73, 69.5 %). While the growth of p. Atlantica and P. Khinjuk rootstocks were stronger than Ashouri rootstocks. The length of Ashouri variety which budded on P. Atlantica and P. Khinjuk rootstocks was (47.36, 49.88 cm), and the diameter was (5.59, 5.67 mm).
