Abstract

The vegetative propagation of passion fruit can provide to obtain uniform seedlings and orchards, with the use of rootstocks with good characteristics such as tolerance to soil-borne diseases. The objective was to study methods of grafting at different ages of passion fruit plants after emergence. The experiment was conducted at the Horticulture Sector, of the Federal University of Lavras (UFLA), in MG, on mesh with 50% shading. The experimental design was randomized blocks in a 2x4 factorial design, two methods of grafting (cleft grafting, splice grafting) and four times in budding (15, 25, 35 and 45 days after emergence). It was evaluated: percentage of grafting success, leaf number, plant height and diameter. It is concluded that the grafting of sour passion fruit on the sweet, both in cleft grafting and splice grafting, the best time to perform is 15 days after emergence, showing an index of grafting success of 98% in both methods.
