The use of tolerant rootstocks has shown good results in the control of Fusarium wilt in yellow passion fruit, which is considered one of the main problems in the crop as it affects the plant’s root system and has no chemical control. The present study aimed to evaluate the survival rates, the agronomic performance of the plants and the physical characteristics of the yellow passion fruit (Passiflora edulis Sims) grafted on different rootstocks in area with Fusarium wilt. The experiment was carried in Pracinha, in the State of São Paulo, Brazil, from August 2014 to May 2015, and a randomized block design was adopted, with five treatments, five replications and four plants per plot. The treatments were constituted by the following rootstocks: Passiflora alata Dryand, Passiflora gibertii N.E. Brown, Passiflora caerulea Linnaeus, double grafting P. gibertii x P. edulis and plants without grafting. The stem diameter of rootstock and the graft, the lenght of secondary branches, the number of tertiary branches, the number of surviving plants, the longitudinal and transversal diameters of the fruits, the number and mass of fruits and the productivity were evaluated. The largest diameter of the rootstock was observed in Passiflora alata while in the graft it was in plants of Passiflora edulis. The length of the secondarty branches and the number of tertiary branches were affected by the type of grafting and the rootstock used. The highest survival rates were observed in Passiflora alata (90%) and Passiflora gibertii (100%). The highest number of fruits per plant and productivity occurred in plants grafted on Passiflora gibertii. The adoption of double grafting using Passiflora gibertii x Passiflora edulis and simple grafting with Passiflora caerulea were not effective in the control of this disease. The species Passiflora gibertii and Passiflora alata showed the potential to be used as a rootstock for yellow passion fruit.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
