The jabuticabeiras are well known trees, mainly in the South, Southeast and Midwest regions of Brazil, because fresh consumption of its fruit, and in the form of jam and liqueur. Despite the potential that has the jabuticabeira it is still kind with few commercial orchards planted. Most of the jabuticabas production is intended for fairs and sold by street. For the jabuticabeira be more cultivated, should be expanded research for the advancement in the domestication through selection, breeding and propagation of genotypes with potential use. The objective of this study was to determine the playback mode (autogamy, outcrossing or mixed system) of two species of jabuticabeira (Plinia cauliflora and P. trunciflora) and check the grafting of interspecific and intergeneric compatibility and the efficiency of two grafting methods. To determine the playback mode of jabuticabeira were made two treatments (T1: unprotected branches; T2: protection of branches with foil). They were marked four branches (repetitions) containing flowers on balloon stage, for each treatment in a jabuticabeira of each species (P. cauliflora and P. trunciflora), located in Itapejara West, Paraná. Initially they were told the balloon stage in flowers and proceeded or not to branch protection with foil and after 35-40 days, were counted ripe fruit in the same lines, accounting for the percentage of fruit set. It tested the feasibility of interspecific grafting P. trunciflora on P. cauliflora rootstocks and intergeneric grafting P. cauliflora on rootstock Psidium guajava (guava), compared to the specific grafting P. cauliflora on rootstocks P. cauliflora. In addition, they compared two grafting techniques: (1) top cleft; and (2) grafting the omega type using equipment (manual). Thus, it is concluded that trunciflora Plinia and Plinia cauliflora are self compatible, but pollinators increase fruiting, This makes the species is of mixed mating system, predominantly crossings. And it is necessary to test grafts that have apical dominance, since the experiment was conducted from subenxertos. |
