Conteúdo: | Cultivation of citrus fruits is important for the development of the Northeast region of Brazil due to some competitive advantages such as land availability, adequate ecological conditions, and geographic localization in relation to internal and external markets. However, these crops present a great vulnerability resulting from low diversification of scion and rootstock cultivars. The objective of this work was to verify the initial development of three orange cultivars in different rootstocks in the semiarid region of the State of Ceará. A completely randomized design was used, with three cultivars (Pera D-6, Valencia Tuxpan and Rubi) and three rootstocks (Santa Cruz Rangpur lime, Citrandarin Indio and Citrandarin Riverside), thus totaling nine treatments with four repetitions per treatment. The soil of the area is Typical Hydromorphic Orthic Vertisol (SiBCS), and the spacing used was 5.0 m x 2.0 m. The parameters evaluated were height (H), diameter between trees (Dl) and between rows (Dr), canopy volume (V3) and stem diameter 5cm above and below the grafting line. Biometric measurements were performed 18, 24 and 30 months after transplantation. The treatments, T1S1-Pera D-6 x Santa Cruz Rangpur lime and T2S2-Valencia Tuxpan x Citrandarin Indio, had significantly different height (H) and canopy volume (V3) at the 18th and 30th month, respectively: Height: T1S1 = 1.20 m and 1.75 m, T2S2 = 1.29 m and 1.84 m; canopy volume: T1S1 = 0.90 m3 and 2.56 m3, T2S2 = 0.87 m3 and 2.77 m3. The combinations Pera D-6 x Santa Cruz Rangpur lime and Valencia Tuxpan x Citrandarin Indio presented better adaptation and vegetative development in the semiarid conditions studied, allowing their indication for use in this region.
