For removing some restrictions of producing apricot in Iran, a project was conducted based on factorial statistical design with 3 replicates at Sahand Horticultural Research Station. At this project, the effects of 2 rootstocks including: seedling apricot (as control) and seedling Myrobalan and also 2 inter-stocks including: Saint Julian A grafted on seedling Myrobalan and a natural almond ¡Á peach hybrid grafted on seedling almond, were studied on 7 native apricot cultivars including: Ordubad, Dorosht-e-malayer, Haftbaradaran, Asgar-abad, Germez-shahroud, Gara-tabarze and Shastomi-yek. Myrobalan was used for its ability in toleration of heavy soils, St. Julian A for decreasing tree height and finally almond ¡Á peach hybrid was used for compatibility between almond and apricot cultivars. The results showed that Myrobalan had perfect compatibility with used apricot cultivars except Shastomi-yek. Also, apricot cultivars showed acceptable compatibility with St. Julian A and vegetative growth traits were decreased by using this inter-stock significantly (p¡Ü1%). The combinations of apricot cultivars and almond ¡Á peach hybrid did not supply our expectation and local incompatibility symptoms such as diametric difference between scion and inter-stock, earlier fall date, formation of necrotic tissue in graft point and exudation of sap were observed obviously in many of them. Furthermore, average survival rate of them was less than 52%. Considering quiddity and short performance time of this project and also for each strongly suggestion, it seems that the project must be continued for at least 5 years.
