A field study was carried out to determine the effects of two types of interstock incision (15 and 30cm lenght) using three Mango varieties (Coquinho, Carlota and Imperial). The effects were also determined using two grafting heights (25 and 55cm) with the var. Tommy Atkins grafted on var. Espada. The results indicated that the treatments did not show any impact on the vegetative growth, rootstock and interstock perimeters, height and diameter of the tree crown, measured six years after incision. The fruit production analised after four harvest seasons, showed certain variation among treatments; they were, however, not statistically significant.
