The aim of this study was to investigate the influence of different methods of grafting the fig tree 'Roxo de Valinhos' in unrooted cuttings of different fig cultivars. Hardwood cuttings of the middle area of the branches were collected of 15 fig cultivars (Brunswick, Calabacita, Negro de Bursa, Mini Figo, Lampa Preta, Lemon, Troiano, Nazaré, Três num Prato, Princesa, Colo de Dama, Montes, Bêbara Branca, Pingo de Mel e Roxo de Valinhos) with four years of age, in the first week of June 2014. The cuttings were standardized with 20 cm, about 15 mm of diameter and four nodes, was made a cut on a bias in base cuttings and another right at the apex. Also were collected cutting from the apical branches from the fig tree 'Roxo de Valinhos' to take out the buds and forks for the grafting. The cuttings were kept humid to favor the grafting operation. Grafts were performed by the methods of budding and grafting. In grafting by budding, we used grafting by the plate type (square cuts of 10 mm between two nodes from the cutting, putting in this spot a bud of the same size) and in the grafting by forks, was made a cut by "T" normal between two nodes from the cutting, putting in this spot forks with three buds and about five cm long (cut beveled at the bottom and straight at the apex), the forks were tied with transparent plastic and protected with transparent plastic bags (18 x 3 cm for 60 days). Then all grafted cuttings were treated in solution of 2,000 mg L-1 IBA for 10 seconds. The cuttings were buried to 2/3 of its length in sand bed of fine granules, under the nursery conditions with 50% brightness. During the experimental, the rooting bed was moistened daily with 20 L of water. The design was completely randomized in a factorial 2 x 15 (2 grafting methods and 15 cultivars ). In 120 days after grafting, was measured the percentage of rooting, percentage of buds and forks alives, percentage of buds and forks alives in rootstocks rooted, percentage of budding of the buds and forks and average length of the budding. It is concluded that the grafting method influences the rooting, survival and budding from the grafts and the fig cultivars used by the graft can influence the growth of the grafts, for the budding method the cultivar Colo de Dama can be used for a rootstock and for the forks method the cultivars Bêbara Branca, Colo de Dama, Nazaré and Troiano can be used for rootstock.
