“…TSxPT 239 was not superior to Rangpur lime (Table 3). In the study by Sombra et al (2019), the ESI values observed for citrandarins Indio (8.00), Riverside (9.75) and San Diego (11.50) were higher than those of citrandarins analyzed in the present study. Higher ESI values indicate that the rootstock presents high vigor and greater initial uniformity in the nursery (Rodrigues et al, 2015).…”

“…For Santos et al (2015), commercial rootstocks must have high seed production and high polyembryony rate. Some agronomic characterization studies of new citrus hybrid rootstocks, mainly citrandarins, with the aim of evaluating and characterizing fruits, seeds and initial seedling development, have been developed in recent years (Schinor et al, 2015;Rodrigues et al, 2015;Conceição et al, 2019;Sombra et al, 2019 From results obtained, analysis of variance (ANOVA) was performed and means were compared by the Scott-Knott test at 5% probability using the SASM-Agri software (Canteri et al, 2001). For statistical analysis, fruit mass averages were transformed into (x + 1) 0.5 and polyembryony into arcsine (x / 100) 0.5 .…”

In citrus cultivation, rootstocks are of fundamental importance and affect several characteristics of the variety used as canopy. Despite the great diversity within Citrus and related genera, the production of rootstocks in Brazil is restricted to a small number of varieties, making the citrus culture vulnerable to the appearance of phytosanitary problems. The aim of this study was to agronomically characterize fruits and seeds of seven citrandarins [Citrus sunki (Hayata) hort. ex Tanaka x Poncirus trifoliata cv. Rubidoux (L.) Raf.], obtained by controlled crossing. The orchard was installed in randomized blocks, with three replicates, in the municipality of Cordeirópolis, SP, where 20 fruits were collected in each replicate, obtained from free pollination of seven citrandarins, Swingle citrumelo and Rangpur lime. The following variables were evaluated: fruit mass, height, diameter, total number of seeds and percentage of viable seeds per fruit; number of embryos per seed, mass of one thousand seeds, number of seeds in 1.0 kg, final emergence rate, number of seedlings per seed, polyembryony rate, emergence speed index and seedling height at 60 days after sowing. For fruit size, the highest values were obtained for Swingle citrumelo. For number of embryos per seed, seedlings obtained through seed and polyembryony, citrandarin TSxPT 245 showed the highest values. Although citrandarin fruits had smaller size than fruits from commercial Rangpur lime and Swingle citrumelo rootstocks, characteristics related to seeds such as viability, polyembryony and emergence rate, were similar or superior, and can be considered potential new rootstocks for the production of citrus plants.

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.
