This study was carried out on grafting plum rootstock (Marianna) (P. Cerasifera x P.munsoniana) at El-Kanater Horticultural Research Station  “Kalubia Governorate", during two successive seasons 1997 /1998 and 1998/1999 Two grafting methods were used for hardwood cuttings of Beauty cultivar (Prunus triflora, L.) on Marianna hardwood cuttings treated with 3000ppm IBA for 10seconds Results revealed the following: 1-     The best success percentage was during December for treated Marianna hardwood cuttings grafted with two methods varied between 70.67 to 79.00%. 2-     Tongue grafting gave the best success percentage comparing with top grafting during the three months (December, January, February). 3-     High length per plant was for Marianna hardwood cuttings treated with IBA at 3000ppm grafted with tunge method during December. 4-     The high values of total number and length of roots < 0.1cm were always for Mariana hardwood cuttings treated with IBA as a rootstock for Beauty plum cultivar, grafted with tunge method during December. 5-     The high dry weight of roots per plant was for Marianna hardwood cuttings treated with IBA during December and January. 6-     Suitable plum grafts could be obtained for planting after one year only.
