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.

Abstract: Knowledge of thermoregulatory responses in taurine cattle contribute to identification of animals most adapted to heat and productive when raised under Brazilian climate. The objectives were to verify the morphological and physiological responses related to adaptation to heat of taurine breeds raised under in Brazilian meteorological conditions in different seasons of the year and day periods, and to detect differences within and between breeds to know breed is most adapted. Measurements were made of 74 young bulls (n=31 Angus; n=43 Simmental) for the morphological traits: hair length (HL), number of hairs (NH), and coat thickness (CT); and for the physiological traits: respiratory rate (RR) and hair coat surface temperature (ST). The temperature-humidity index (THI) was calculated. The data were subjected to analyses of variance, cluster analysis, and principal component analysis (PCA). The THI (< 74) indicates thermal comfort. In the winter, the HL and CT higher than in the spring season (P < 0.0001) in both breeds. Angus exhibited higher HL and CT (P < 0.0001). Within each breed, the animals differed from one another for HL (P < 0.0005). In the spring, CT was similar between the breeds, differing only in the winter season. Angus had higher values (P < 0.0005) of RR and lower values (P < 0.0001) of ST. Both breeds had higher (P < 0.0001) RR and ST in the afternoon. PCA showed that NH and HL better explained variation in adaptation. In general, the breeds have similar morphological responses in the hottest months, but have different physiological responses; Simmental proves to be more physiologically resistant. The afternoon was more stressful than the morning, even though the animals were in a thermal comfort zone. Measuring traits related to hair coat is sufficient for effective evaluation of adaptation, and the season affects the morphological and physiological traits of taurine cattle raised.
