ABSTRACT
During 2008-2010, the RIFG Pitesti-Maracineni and nursery Aiud have conducted research on organic product "Ceraltin®", developed by Bios-Cluj-Napoca, in order to increase the percentage of graft attachment to some cherry varieties that have a lower degree of compatibility with native vegetative rootstocks. The biological material consisted of cherry varieties: Daria, Superb, Van and Maria -first self-fertil variety created in our country and the vegetative rootstocks IP-C 4 and IP- C7. As methods of grafting were experienced the cleft grafting and chip budding". "Ceraltin® product was applied in two bindings, before and after grafting. They followed the process of callusing, vascular connection and welding at the point of grafting. The subsequent increases of the grafted scions were monitored from early May until late October, by determining the grafting percentage of attachment and growth potential, and morphological and physiological indices of the thickness in grafting zone. Data revealed that in the product "Ceraltin® "variant, the thickening ratio in the grafting area between the symbionts was closer by unit, the vascular connections were made quickly to chip budding . Instead, in the cleft grafting, the callusing and welding processes were developed slowly over a period of two years, and were dependent on the thickness of the rootstock at the point of grafting, at all studied variants.
