Conteúdo: 	tThe grafting of the yellow passion fruit onto wild species tolerant to Fusarium spp. is an alternativepractice for this disease control. High vigor and tissue compatibility between the scion and the rootstockare critical for the production of grafted passiflora nursery trees. The initial plant growth and histologicalaspects of the graft union were evaluated on two Passiflora edulis genotypes grafted onto P. edulis, P.gibertii, P. alata, P. nitida and backcross BC1 [(P. edulis x P. cincinnata) x P. edulis]. Plant survival washigh (?90%) up to 60 days after grafting, regardless of the scion neither the rootstock, and in relation tothe respective non-grafted seedlings. P. gibertii resulted in higher plant emergence after P. edulis, highergrowth of seedling rootstocks and induced higher length of the P. edulis graft. The complete union betweentissues was observed in P. edulis grafted onto P. edulis, P. gibertii and BC1 60 days after grafting. On theother hand, a discrete structural disorganization with incomplete adhesion and phenolic compoundsaccumulation was verified in the connection of P. edulis onto P. nitida and P. alata, suggesting partial graftincompatibility, even though grafted plants growth was restored. All evaluated genotypes have potentialof use as rootstock of the yellow passion fruit. The graft connection may be enhanced on hybrid rootstocksof P. edulis with wild species.
