The yellow passion fruit tree (Passiflora edulis Sims.) main Passifloracea cultivated in Brazil, has been registering reduction in the longevity of the orchards throughout the years, due to the incidence of illnesses that attack its radicular system. The challenge is to search for mechanisms that make possible to extend the cycle of this culture. The objective of this work was to compare the index of establishment and precocity in the emission of tendril of the grafting variety 'FB200' in the rootstocks: P. edulis, P. quadrangularis, P. giberti, P. coccinea, P. alata, P. clear and in the variety 'FB200' (yellow passion fruit tree). The experiment was carried out in a nursery under fabric (50% of shade), in the Experimental Farm of the FAMEV/UFMT. The rootstock and grafting had been deriving of seeds, from Flora Brazil Nursery (Araguari-MG), UNESP/Jaboticabal-SP and collected in the region. The grafting method was of full cleft grafting using rootstock with three leafs and height of 15 the 30 cm until the grafting point. The seedlings presented at the moment of the grafting, about 30 to 90 days. The experimental delineation was entirely randomized, with seven treatments and three repetitions, where each repetition was formed by 15 grafting seedlings. The index of establishment and the emission of tendril had been evaluated in biweekly intervals, until the 60 and 120 days respectively. Grafting seedlings of the passion fruit tree 'FB200' in Passiflora edulis, P. quadrangularis and in 'FB200', presents optimum index of establishment of the grafting and precocity in the emission of tendril, been apt to be led to the field after 30 to 120 days of grafting.
