The top-cleft grafting was evaluated in native species Piper arboreum Aubl., P. aduncum, and P. tuberculatum with Balankotta pepper cultivar as graft using black pepper cv. Bragantina (Experiment 2). Black pepper cv. Bragantina autograft was considered as control. The rootstock P. tuberculatum showed initial incompatibility with the cv. Bragantina, with survival of about 34.8% (side) and 62.5% (top) and total inhibition of graft shooting. The side and top graft on P. aduncum resulted in 84.0 and 47.5% of survival, respectively. The JIP-test parameters indicated better photochemical efficiency in the species grafted using the method of side-cleft grafting. Finally, the initial compatibility was associated with greater survival, shooting, and better energy flow through the electron transport chain.  aPiper aduncum  aPiper hispidum  aPimenta  aPimenta do Reino  aPorta Enxerto  aPropagação Vegetativa  aBRS Kottanadan1 aCERRI NETO, B.1 aPINTO, M.L.P.B.1 aFERREIRA, T.R.1 aARANTES, L. de O.1 aMACHADO FILHO, J.
