abstract = {Pera sweet orange (Citrus sinensis L. Osbeck) is the most important mid-season sweet orange cultivar in Brazil, not only because of its desirable fruit quality for both juice processing and the fresh fruit market, but also because there is a lack of adequate mid-season alternative sweet orange cultivars. This study aimed to evaluate the horticultural performance of other sweet oranges in an attempt to identify similar or superior selections to the standard cultivar, Pera IAC sweet orange. Seventeen sweet oranges selections, including the standard Pera IAC, were budded on Sunki mandarin [C. sunki (Hayata) hort. ex Tanaka]. The experiment was planted in 2007, using 12-month-old nursery trees, with 6.5 × 2.5 m spacing in the Southern region of São Paulo state, Brazil. The experimental orchard was maintained with standard commercial management practices, and without supplementary irrigation. Data collection started three years after planting and was carried out until seven years after the experiment had been installed. Vegetative growth, plant yield, fruit drop, fruit quality, and fruit maturation regressions were assessed. Averages of the alternative selections were compared with those of the standard cultivar by Dunnett test. Performance indexes were calculated in order to identify potential superior selections for the fresh fruit market and for juice processing. Results indicated significant differences among the selections evaluated when compared with the standard cultivar, suggesting better alternatives to be exploited. Five selections (Biondo, Finike, Pera Alexandre Maróstica, Seleta Rio, and Vaccaro Blood) offered superior performance in terms of attributes required for the fresh fruit market, while one selection (Pera Alexandre Maróstica) was superior for juice processing traits. These alternatives to Pera IAC represent an opportunity for more efficient and productive scions with higher fruit quality, and with a slight shift within the mid-season harvest time of sweet oranges in Brazil.},

abstract = {The management of soil cover plants (intercropping) in orchards can contribute to increase productivity of citrus trees. Thus, the present research aimed to evaluate different planting systems for Tahiti acid lime grafted onto Flying Dragon trifoliate orange, a dwarfing rootstock, at high planting density (1,157 trees ha–1). The study was set up in four tillage systems, using Urochloa ruziziensis as an intercrop species in the orchard, and conducted for 5 years: no-tillage (NT), no-tillage and no-herbicide (NT-NH), minimum tillage (MT) and conventional tillage (CT; without intercropping). Dry matter (DM) production of biomass in the row and interrow of the orchard was evaluated yearly, as well as weed density, soil physical and chemical characteristics, plant water and nutritional status, and fruit yield of trees. Greater deposition of DM of biomass was observed in the row of citrus planting for treatments NT and NT-NH compared to CT and MT treatments, which led to reduced undesirable weed populations. The NT treatment also provided increases of 79% in potassium (K) nutrient concentrations in the leaves of trees and 60% in exchangeable K in the soil surface layer, in the first 2 years evaluated. The maintenance of the Urochloa ruziziensis mulch in the NT system also provided higher soil volumetric moisture content and consequently lower soil resistance penetration and water stress on trees, evidenced by the predawn plant leaf water potential (<1 MPa). Moreover, the NT treatment provided an average increase of 56% of fruit yield from trees compared to the CT treatment during three harvests. This long-term study demonstrated the contribution of the no-tillage system using a favorable cover crop to increase the yield of Tahiti acid lime fruits and maintain the soil quality most required for the sustainability of citrus production.},

abstract = {Naturally occurring subsoil horizon restricting root development and a narrow genetic base of scion-rootstock combinations make the citriculture in Brazilian Northeast prone to biotic and abiotic stresses. The diversification of citrus orchards through the introduction of new scion-rootstocks combinations is an important strategy to reduce the risks associated with these constraints. Three experiments aiming at identifying appropriate scion-rootstock combinations for enhancing genetic diversification in citrus orchards under rainfed conditions in tropical hardsetting soils were established in Sergipe state in 2008. In each one, a different sweet orange (‘Sincora’ ‘Valencia Tuxpan’ and ‘Pineapple’) was grafted on six rootstocks (‘Santa Cruz’ Rangpur lime, ‘Red Rough’ lemon, ‘Orlando’ tangelo, ‘Sunki Tropical’ mandarin, HTR–051 and VKLxRPL–010 hybrids). After eight years the experiments were evaluated for plant development, yield performance and fruit quality. In general, all sweet oranges grafted on ‘Red Rough’ lemon showed great development and cumulative yield as does with ‘Santa Cruz’ Rangpur lime, with the later showing better fruit quality as an advantage. Inversely, HTR-051 hybrid displayed low yields despite high yield efficiency, for this rootstock induces dwarfism. ‘Sunki Tropical’ mandarin brought high yields of medium quality fruits, while the VKLxRPL-010 hybrid induced productive precocity, especially for ‘Sincora’ sweet oranges. Based upon these results, all tested scions grafted on ‘Red Rough’ lemon and ‘Santa Cruz’ Rangpur lime, followed by ‘Sunki Tropical’ mandarin are indicated for genetic diversification of groves, when planted at conventional density. On the other hand, the hybrid HTR-051 seems to have great potential for high density orchards, since it shows high yield efficiency and good quality of fruit.},

abstract = {Abstract: The objective of this work was to evaluate the effect of nine rootstocks on 'Jaffa' sweet orange (Citrus sinensis) for its vegetative, productive, and qualitative traits, and for its susceptibility to three pest mites (Eutetranychus banksi, Tetranychus mexicanus and Phyllocoptruta oleivora). The following parameters were evaluated: vegetative growth, yield, physiochemical characteristics of fruit, and density of pest mites. 'Sunki Tropical' mandarin conferred high cumulative yields whereas 'Orlando' tangelo and 'Rugoso Vermelho' lemon imparted bigger fruit with low brix, and less acidity to 'Jaffa'. Indio and 'Riverside' citrandarins induced more acid fruit of smaller sizes, as well as low-cumulated yields and canopy volumes. Also, the 'Cravo Santa Cruz' lime, 'San Diego' citrandarin, and the hybrids HTR-051 and LVK x LCR-010 conferred lower-cumulated yields to 'Jaffa'. The rootstocks did not influence the population levels of the evaluated mites. 'Sunki Tropical' mandarin, 'Cravo Santa Cruz' lime and 'Rugoso Vermelho' lemon stand up as excellent rootstock options for 'Jaffa' sweet orange in the Northeastern Brazil.},
