“…Orange production is directly related to tree growth development [7,10,30,31]. In our trial, trees on F.80-3 and F.80-5 citrumelos, IPEACS-256 and IPEACS-239 citrandarins and 'US-802' pummelo hybrid had low yield, mainly due to their dwarfing potential.…”

The low diversification of rootstock genotypes in orchards limits the expansion of the citrus industry, restricting increases in productivity and cost-saving via phytosanitary treatments and other horticultural practices. Therefore, the aim of this study was to assess the impact of rootstock genotypes on tree development and industrial properties of ‘Valencia’ sweet orange juice (Citrus sinensis). Twenty rootstock genotypes were evaluated by measuring tree growth and industrial properties of orange juices, including ‘Trifoliata’ hybrids with tangerine (citrandarins) and grapefruit (citrumelos), as well ‘Rangpur’ lime and other potential rootstocks. The experimental orchard was planted in Rancho Alegre, PR, Brazil, under clay soil and subtropical rainfed conditions. A randomized block design with four replicates was used. Trees grown on IPEACS–239 and IPEACS–256 citrandarins, and on ‘US–802’ pummelo hybrid had low vigor, high production efficiency and high industrial properties of orange juice, and are therefore potential alternatives for high-density plantings. The F.80–3 and F.80–5 citrumelos also had good dwarfing potential and high production efficiency, but lower industrial properties of juice compared to the other ‘Trifoliata’ hybrid rootstocks. Trees grown on ‘US–812’ citrandarin rootstock had low vigor, good productive performance, accumulated production and production efficiency similar to ‘Rangpur’ lime, and high industrial properties of juices. Although the ‘Rangpur’ lime and the ‘Florida’ rough lemon allowed high yields, the trees are very vigorous, with low-quality fruits. A Quick Reference Chart was created to provide practical and objective identification of the best rootstock alternatives for ‘Valencia’ orange trees in terms of tree development and industrial properties of juices.

“…In other words, without rootstocks, own-rooted orange trees may have a poor development or even die in a short period of time. However, only few rootstock varieties are used in citrus cultivation in many countries, and this poses a health-risk for trees, and often limits the performance of scion varieties and orchard yield [5][6][7].…”

“…The average productivity of these three rootstocks in the evaluated period was around 18.4 t..ha -1 , being higher than the Bahia (12.3 t•ha -1 ) and Sergipe (11.6 t•ha -1 ) averages for sweet orange fruit yield, yet lower than the Brazilian average (28.95 t•ha -1 ) in 2020 (IBGE 2020). The 'Tropical Sunki' mandarin induced high productivity to other sweet orange varieties, such as 'Tuxpan Valencia' , 'Jaffa' , 'Pineapple' and 'Sincorá' , compared to drought-tolerant 'Rangpur' lime and 'Rough' lime rootstocks in similar rainfed conditions in northeastern Brazil (França et al 2016;Teodoro et al 2020;Carvalho et al 2019). Costa et al (2020) observed similar productivity of 'Valencia' sweet orange grafted on the 'Rangpur' lime and 'Tropical Sunki' mandarin without irrigation under tropical savannah climate, thus, taken together, these results reinforce the potential of the later rootstock for the citrus industry, including the most important Brazilian scion variety, the 'Pera' sweet orange (Cunha Sobrinho et al 2013;Fundecitrus 2020).…”

‘Tropical Sunki’ mandarin and hybrid citrus rootstocks under ‘Pera’ sweet orange in cohesive soil and As climate without irrigation

The search for alternative rootstocks to the 'Rangpur' lime tree is a challenge to the sustainability of citrus in the Tabuleiros Costeiros (Coastal Tablelands) of Northeastern Brazil. New varieties should meet high drought tolerance with water deficit, cohesive soils, resistance to citrus diseases and inducing high production of fruit. In this work, the performance of 'Pera' sweet orange was evaluated on 'Tropical Sunki' mandarin and 27 hybrid citrus rootstocks in Umbaúba, Sergipe. A local selection of the 'Rangpur' lime was the control. Planting was in 2013 at tree spacing of 6.0 × 3.0 m, without irrigation. Tree size, fruit yield and quality, tree survival rate and graft-compatibility were assessed until 2019. Experimental design was completely randomized blocks with 29 treatments, three replicates and four plants in the plot.Two selection indices were applied to the data to assist in decision making. The 'Tropical Sunki' mandarin induced similar cumulative fruit yield in relation to the 'Rangpur' lime, suggesting a good drought tolerance of the former rootstock. The TSKC × (LCR × TR) -073 induced slightly lower productivity, compensated by higher productive efficiency and higher concentration of soluble solids, whereas LCR × TR -001 and HTR -166 were highly efficient dwarfing rootstocks. The multiplicative and the rank sum indices showed high correlation, both classifying 'Tropical Sunki' mandarin, 'Santa Cruz Rangpur' lime, LVK × LCR -010 and -038, HTR -127, in addition to the three aforementioned hybrids, as superior to the local selection of 'Rangpur' lime.

“…Entretanto, o porta-enxerto 'Sunki' favoreceu a indução da produtividade a outras variedades de laranja doce, como 'Tuxpan Valencia', 'Jaffa', 'Abacaxi' e 'Sincorá', levando-se em consideração os porta-enxertos de limão 'Cravo' e limão 'Rough' que são resistentes à seca (França et al 2016;Teodoro et al 2020;Carvalho et al 2019). Para Passos e Silva (2018), o portaenxerto 'Sunki Tropical' apresentou um bom desenvolvimento nos parâmetros de altura de planta e diâmetro do caule, bem como são os melhores incrementos em mudas de laranjeira 'Pêra', no município de Capitão Poço-PA.…”

Na citricultura, a diversificação da combinação de copas e porta-enxertos é uma necessidade para obter sucesso no pegamento do enxerto, diminuir o tempo de estabelecimento da planta no campo e melhorar o potencial produtivo. Dessa forma, esse trabalho tem como objetivo avaliar o desenvolvimento inicial de combinações de copas de laranjeiras doces ('Pera D6', Pera rio e Natal) com porta-enxertos de citrandarin (San Diego) e tangerineira (Sunki tropical). O experimento foi realizado em casa de vegetação pertencente a Fazenda Lima, localizada no município de Capitão Poço, Estado do Pará. Foi utilizado delineamento inteiramente casualizado, arranjados em esquema fatorial 2x3, sendo um porta-enxerto de citrandarin (San Diego) e um de tangerineira (Sunki tropical) e três copas de cultivares de laranjas doce ('Pera D6', Pera rio e Natal). A técnica utilizada foi a borbulhia por T-invertido. Após 12 dias da realização da enxertia foi removida a fita de enxerto e com 26 dias após a enxertia foram coletadas as variáveis altura do enxerto, diâmetro do caule dos enxertos e quantidade de folhas do enxerto. Os dados obtidos foram sujeitos ao teste de normalidade de Shapiro-Wilk e análise de variância, as médias foram comparadas pelo teste de Scott-Knott 5%, com o auxílio do software ASSISTAT. A combinação entre laranjeira ‘Pera D6’ e tangerineira Sunki tropical apresentou melhor desenvolvimento inicial.
