The interstock is a practice used when to merge two plants that are known to be incompatible or when it is intended to low vigor of the scion. In this study we evaluated an alternative method for the production of Pêra sweet orange nursery trees interstocked, using the technique as inarching assist in forming a interstock of Rangpur Lime (RL). The treatments were: T1 - rootstock trifoliate Flying Dragon (FD) and interstock of sweet orange Bahia, T2 - rootstock Citrumelo Swingle (CS) and interstock of sweet orange Bahia, T3 - rootstock Rangpur Lime (RL); T4 - rootstock FD and interstock RL; T5 - rootstock CS and interstock RL. The sweet orange nursery trees produced in treatment 4 (Pêra / RL / FD) had vigor nearest sweet orange nursery trees produced with interstock (Pêra / RL). The production Pera sweet orange nursery trees interstocked for traditional system, with the rootstock CS or FD and interstock sweet orange Bahia was not possible because of the low viability and vigor of the shoots.
