Vegetative growth of passiflora edulis' brs gigante amarelo 'is influenced significantly by grafting
Although Brazil is the largest producer of passion fruit, the mean fruit yield is only 13 t ha-1 and may be attributed to susceptibility to pests and diseases. An attractive solution to the problem would be to improve traits by grafting onto a rootstock presenting enhanced vegetative vigor. To this end, the commercial cultivar Passiflora edulis 'BRS Gigante Amarelo' was grafted onto rootstocks that included three native species of Passiflora and four passion fruit hybrids that are still under development.
