Abstract

This work aimed to evaluate the top cleft grafting, grafting under peel and budding and the position of collection influence of the propagules inside of the main plant on the survival of the grafts accomplished directly to field in Ilex paraguariensis. The experiment was carried out in the Ãurea municipal district, State of Rio Grande do Sul, with propagules originated from a main tree with more than 80 years old. Three separate material types composed the treatments: sprouts of the base, of the medium part and of the apical part of the main tree. In a general way, the grafting technique at the field was shown viable, although the survival results of the grafts at the 300 days showed low (from 0 to 30%). Grafts that died after the 65 days already presented sprouted, indicating damages by excess of heat. The grafting method in full rift was shown as the most appropriate, given the union largest resistance of the graft with the rootstocks. The propagules position in the main plant did not influence the grafts survival.
