Olive is a leading Mediterranean specie with over 1000 species described. Over 60% of olives in Croatia is the variety of Oblica, which in some circumstances does not give satisfactory yield and there is a need to introduce new olive varieties. Under these conditions, the best way is to graft the existing trees. The field research experiment was set up in 2016 using the rootstock of the Oblica on which was graft the four prospective varieties: Krvavica, Levantinka, Lastovka, Istrian bjelica. In this experiment there were used scions that were kept in the refrigerator and scions of the same varieties harvested on the day of grafting, with the purpose of determining whether there was a difference in the reception between the new scions and those which had been kept in the refrigerator. The aim was also to determine whether there was a difference in the reception between the olives cultivated on the Oblica rootstock. The purpose of the work was to collect expert information related to grafting. The research results show that the compatibility of the variety that was the rootstock and the varieties that were used for the scions is good. There was also a difference between newer scions and those from refrigerators but different for each species.
