Abstract

The use of rootstock in the cultivation of passion fruit aims to solve problems related to diseases caused by soil-borne pathogens. The seedling production by this method may provide greater longevity for plants and smaller losses for the producer of passion fruit. The objective of this study was to evaluate the grafting of different canopy / rootstock, using Passiflora alata and Passiflora cincinnata as rootstocks for yellow, sweet and purple passion fruit plants. The experimental design was completely randomized in a factorial 2 x 3 scheme (two rootstocks and three types of scions), with four replications and ten plants per plot. The Passiflora cincinnata when used as rootstock for yellow, purple, and sweet passion fruit showed lower grafting success rate and seedling development. The formation of seedlings by grafting of yellow and purple passion fruit on Passiflora alata proved to be feasible for the majority of those characteristics.
