METHODOLOGY OF MINIGRAFTING ON PASSION FRUITS

The objective was to evaluate the graft methodology based on cleft grafting on the top of the hypocotyls, using adult minicuttings of apical segments of P. edulis f. flavicarpa, P. edulis, P. alata, P. mucronata and P. foetida, and intermodal of P. mucronata. The experiments were carried out under greenhouse conditions, equipped with intermittent mist irrigation, at Centro Universitario Norte do Espirito Santo (CEUNES), Universidade Federal do Espirito Santo (UFES). The rates of grafting success in combinations of P. edulis f. flavicarpa/P. edulis f. flavicarpa, P. edulis/P. edulis f. flavicarpa, P. alata/P. edulis f. flavicarpa, P. mucronata/P. edulis f. flavicarpa, P. foetida/P. edulis f. flavicarpa were 90, 90, 68, 80 and 90, respectively. The proposed methodology is a novel grafting option for those species of the genus Passiflora.
