The objective of this study was to test the viability of the technique of green grafting in natives Myrtaceae. The experiment was conducted in greenhouse conditions of the Departamento de Horticultura e Silvicultura / UFRGS, in Porto Alegre. Two species of Myrtaceae were used, as well as rootstock and as graft, Eugenia uniflora (Surinam cherry) and E. involucrata (Rio-grande-cherry or Cherry of the woods), totaling four combinations. The adopted grafting method consisted to cleft the graft on herbaceous branches, with an average diameter of the rootstock of 0.1 cm, while the branches of the grafts had an average diameter between 0.08 to 0.1 cm for both species. The observations were carried out every two weeks, and after 70 days were statiscally analyzed. The experimental design was completely randomized with four replications, each experimental unit consisting of five grafts. The results indicated 60% of sucess in the combination Surinam cherry-Surinam cherry (rootstock-graft). When Surinam-cherry was grafted on Rio-grande-cherry the low union obtained indicates the possibility of interspecific grafting.
