ABSTRACT
Tropical and subtropical fruit production plays an important role in the country’s economic scenario and has been affected by root-knot nematode. The jaboticaba tree is a plant widely cultivated in Brazil, and among the problems of the crop is the root-knot nematode of the genus Meloidogyne. This study aimed to evaluate the hostability of jaboticaba tree cv. ‘Sabará’, in different inoculum concentrations of Meloidogyne incognita and Meloidogyne javanica. The inoculum used in the experiment was obtained from the roots of tomato cv. ‘Santa Cruz’. Jaboticaba trees were subjected to inoculation with concentrations of 0, 2000, 4000, and 8000 eggs + juvenile plant-1, for both species of nematodes. The plants of jaboticaba cv. ‘Sabará’ showed resistance concerning the development of M. incognita and M. javanica root-knot nematode with Reproduction Factor (RF) <1.
