The objective of this work was to evaluate the seedlings development of yellow passion fruit tree ' FB200' grafted in six species and in the plant itself as a rootstock. the work was developed on the experimental Farm of the FAMEV/UFMT between February and June /2006. the used method of grafting was the type full cleft grafting, carried out above the third leaf and to a changeable height depending on the species (from 15 to 30 cm of height). the species used as a rootstock were: Passiflora edulis, P. quadrangularis,P. giberti,P. alata,P. coccinea, P. nitida and the variety FB 200; and as grafting `FB200'. the following characteristics had been evaluated to measure the development of the plants: height, diameter, number of leaves and internodes, in a period of 60, 75, 90,105 and 120 days after the grafting. the seedlings of variety FB200 produced through the method of grafting for full cleft grafting presented a satisfactory development in the conditions of the cuiabana-Mt Depression, when grafted in the rootstock Passiflora edulis and `FB200'. A great difficulty for the production of passion fruit tree seedlings by using the species P. giberti, P. coccinea and P. nitida as a rootstock is the small and slow development of the stalk diameter of these species.
