“…At this point, more than 50 % of the cuttings were optimal for grafting (diameter > 6 mm), with the hybrid H49 performing better (Table 5). Pio et al (2006) 22.5 % of the somatic hybrid 'Rangpur' lime x 'Sunki' mandarin cuttings were optimal for grafting (diameter > 6.5 mm) at 210 days after the transplant into bags. They stated that even though the cuttings propagation has a comparatively longer period than rootstocks produced by seeds, this method is appropriate, given the good budtake percentages, compatibility and vigor.…”

Propagation by cuttings is an alternative for obtaining citrus rootstocks. The exogenous application of indolebutyric acid (IBA), cutting collection season and genotypes used may affect the rooting and vegetative growth of citrus rootstocks cuttings. Two experiments were conducted to study the influence of these factors. In the first one, semi-hardwood cuttings from the 'Sunki' mandarin hybrids H49 and H77 were collected in the fall and late spring of 2013 and treated with IBA (0 mg L-1, 1,500 mg L-1 and 3,000 mg L-1). For each collection season, a 2 x 3 (two genotypes x three IBA concentrations) factorial scheme was adopted, in a randomized blocks design. In the second experiment, the development of cuttings that rooted in the late spring was evaluated until grafting. In this case, a completely randomized experimental design was adopted, with the hybrids H49 and H77. The IBA treatments positively influenced rooting and number of roots only in the fall collection, peaking at 23.3 % of rooted cuttings. In the late spring collection, rooting was close to 100 %, with the IBA treatment being unnecessary. Around 50 % of cuttings from the 'Sunki' mandarin hybrids were ready for grafting at 14 months after cutting.

“…Estacas das plantas-matrizes dos híbridos somáticos foram induzidas ao enraizamento pela imersão em solução de ácido indolbutírico (AIB) na concentração de 1.000 mg.L -1 , por 10 min e permaneceram em câmara de nebulização intermitente por aproximadamente 100 dias até o transplantio (PIO et al, 2006). Plantas de limão 'Cravo' (C. limonia Osbeck), laranja 'Caipira' (C. sinensis), laranja-azeda (C. aurantium) e Poncirus trifoliata 'Davis A' (Poncirus trifoliata), obtidas de sementes de frutos coletados da coleção de germoplasma de citros da USP/ESALQ, foram utilizadas como controle devido à reação conhecida aos patógenos estudados.…”

Este trabalho avaliou a resistência à infecção de tronco e de raízes por Phytophthora nicotianae em híbridos somáticos de citros com potencial para serem utilizados como porta-enxertos. Os híbridos somáticos avaliados foram laranja 'Hamlin' (Citrus sinensis) + toranja 'Indian Red' (Citrus grandis) (plantas 1 e 2) e laranja 'Hamlin' (C. sinensis) + toranja 'Singapura' (C. grandis). Plantas de limão 'Cravo' (Citrus limonia), laranja 'Caipira' (C. sinensis), laranja-azeda (C. aurantium) e Poncirus trifoliata 'Davis A' (Poncirus trifoliata) foram utilizadas como plantas-controle devido à reação conhecida à infecção pelo patógeno. Avaliações realizadas entre 30 e 60 dias após as inoculações com o patógeno incluíram o comprimento das lesões no tronco e a massa seca do sistema radicular nas plantas avaliadas. O híbrido somático laranja 'Hamlin' + toranja 'Indian Red' (planta 1) mostrou-se tolerante a P. nicotianae, indicando potencial para continuidade nas suas avaliações como porta-enxerto para citros.

“…Por lo tanto, su forma de propagación merece cuidados, buscando la garantía de su expansión e implementación a nivel nacional. una alternativa a la propagación sexuada del mandarino 'Sunki' es la propagación por estaquillas, que posibilita la producción rápida de plántulas, en cualquier época del año, evitando la selección de seedlings zigóticos.estudios empleando reguladores del desarrollo, como el ácido indolbutírico (AIB) comprobaron su eficiencia en cítricos propagados bajo estaquilla, aunque los resultados sean dependientes del genotipo, época de colecta, edad de la planta matriz, condiciones de propagación o sustratos (BuShAl et al, 2001;PIO et al, 2009). en el citrón (Citrus medica l.), por ejemplo, sin el empleo del AIB el enraizamiento fue altamente favorable (>70%) (Al-zevARI y Al-BRIFKAnY, 2015).…”

RESUMEN -los patrones se obtienen tradicionalmente en la citricultura a partir de semillas, seleccionándose las plantas de origen apomíctica. Sin embargo, hay riesgo de no realizarse la selección correcta, debido a la baja apomixis y la alta heterocigocidad en algunas especies o cultivares, como el mandarino 'Sunki'. la obtención de los mismos por estaquillas solucionaría el problema. el objetivo de este trabajo fue evaluar el potencial de enraizamiento de estaquillas del mandarino 'Sunki' (Citrus sunki hort. ex tan.), colectadas de matrices cultivadas en el campo o en ambiente protegido, utilizándose diferentes concentraciones del ácido indolbutírico (AIB). Las estaquillas se colectaron en el final de la primavera y se mantuvieron por 90 días en cámara de nebulización intermitente. Se adoptó el diseño experimental de bloques completos al azar, con cuatro repeticiones, en arreglo factorial 2 x 4, referente a dos condiciones de cultivo (matrices cultivadas en campo y en ambiente protegido) y cuatro concentraciones del AIB (0, 750, 1.500 y 3.000 mg l -1 ). el enraizamiento del mandarino 'Sunki' fue elevado, alcanzando el 96% en las dos condiciones. la brotación (54%) y la supervivencia (95%) de las estacas presentaron valores satisfactorios, independientemente del AIB. el empleo del AIB solamente es necesario en estacas provenientes de plantas mantenidas en el ambiente protegido, puesto que mejora su enraizamiento y el número de raíces. Palabras-clave: Citrus sunki, enraizamiento, fitorregulador, patrón GROwING CONDITIONS Of ThE MOThER PLANT AND USE Of IBA IN ThE PROPAGATION Of 'SUNKI' MANDARIN BY CUTTINGSABSTRACT -citrus rootstocks are obtained from seeds, selecting the apomitic seedlings. however, there is risk of not making the correct selection, due to low level of polyembryony and high heterozygosity in some species or cultivars, such as 'Sunki' mandarin. therefore, obtaining the citrus rootstocks through cuttings may solve the problem. the objective of this study was to evaluate the potential of rooting semi-hardwood cuttings of 'Sunki' mandarin (Citrus sunki Hort. ex Tan), collected from mother plants cultivated on the field or in a greenhouse, using different concentrations of indolbutyric acid (IBA). cuttings were collected in late spring and maintained for 90 days under greenhouse mist system. completely randomized block design was used, with four replications in a factorial 2 x 4, concerning to two culture conditions (mother plants cultivated on the field and in a greenhouse) and four concentrations of IBA (0, 750, 1.500 and 3.000 mg L -1 ). the rooting of 'Sunki' mandarin was high, reaching 96% in both conditions of culture. the sprouting (53%) and survival (95%) of the cuttings showed satisfactory values, regardless of the IBA. the use of IBA is only necessary in cuttings originated from plants kept in greenhouse, improving rooting and number of roots.
