Abstract:
This study was conducted to evaluate the effect of interstocks on three mango cultivars (‘Tommy Atkins’, ‘Van Dyke’ and ‘Rosa’). The experiment was carried out in a mango orchard of Frutan, at José de Freitas district, Piaui State, Brazil. The trees were 5 years old, grown at 9 m x 7 m plant spacing and irrigated by a microirrigation system. ‘Fiapo’ was used as rootstock and ‘Mallika’, known as a dwarfing cultivar, was used as the interstock. The experimental design was a complete randomized block, with four replications and three plants per plot. The characteristics evaluated were: plant height, canopy diameter, and stem diameters of the rootstock, interstock and graft. The results showed that the interstock did not reduce mango tree growth. However, significant differences were observed among cultivars, where ‘Rosa’ showed the lowest values for all characteristics evaluated.
