“…(Asaah et al 2011). In temperate fruit trees, this method has a high rate of success, generally above 95 % (Leite et al 2013). However, for araucaria this technique was not feasible, a fact expressed by the low graft survival observed in the present study (figure 3), as well as the results described in Gurgel and Gurgel-Filho (1967).…”

SUMMARYAraucaria angustifolia (araucaria) is a remarkable species in the Mixed Ombrophilous Forest. The low germination of the stored seeds and its long reproductive cycle make grafting a good alternative for propagation, making possible to obtain genetically superior trees with early fruiting. However, araucaria grafting is still fraught with technical problems, culminating in low graft survival. With the objective to define and be able to explain the best methodology for the grafting of araucaria, we conducted studies based on five experiments evaluating the effects of: (I) environment and sex on graft survival; (II) methods of grafting and budding with shoots from stumps of stock plants; (III) techniques, indoor (nursery) and outdoor (directly in the field) grafting; (IV) budding with buds from different origins; and (V) chip budding with shoots from pruned apices of two ages stock plants. Graft survival was assessed throughout the experiments and the graft-union at the end. The use of controlled environments for grafting was favorable, especially in the glasshouse (64.1 % survival). Scions from female plants (55.5 % survival) showed higher suitability for grafting. Chip budding with shoots from pruned apices of 25 and 35-year-old stock plants showed survival of 87.5 % and 85.0 %, respectively. It is a technology that has unlimited potential for araucaria grafting, which may significantly contribute to its sustainable use.Key words: budding, Brazilian pine, clonal propagation, seed orchard, cleft graft. RESUMENAraucaria angustifolia (araucaria) es una especie que se destaca en el bosque de araucaria. La baja germinación de las semillas almacena-das y su ciclo reproductivo largo hace que la injertación se presente como una alternativa para la producción de plantas seleccionadas, genéticamente superiores y con mayor precocidad para fructificación. Sin embargo, la injertación en araucaria aún presenta problemas técnicos, culminando con una baja supervivencia de los injertos. Con el objetivo de definir y explicar el mejor método para la injertación de araucaria, se llevaron a cabo estudios basados en cinco experimentos que evaluaron el efecto de: (I) los ambientes y el sexo en la supervivencia del injerto; (II) métodos de púa en hendidura y de yema con brotes de cepa; (III) injertación directamente en campo y vivero; (IV) injerto de yemas de diferentes orígenes; (V) injerto de yemas de brotes de ápices de árboles adultos podados con dos edades. Fueron evaluadas la supervivencia de los injertos durante los experimentos y el prendimiento de los injertos al final. La utilización de ambientes protegidos para la realización de la injertación fue favorable, destacándose el invernadero de vidrio (64,1 % de prendimiento). Yemas provenientes de plantas matrices femeninas (55,5 %) mostraron mayor aptitud para la injertación. El injerto de yema en placa de brotes de ápices de árboles adultos podados, 25 y 35 años, presentó resultados de 87,5 % y 85,0 %, respectivamente. Es una tecnología que tiene gran potencial para el uso...

“…Em outras espécies frutíferas também foi verificado, em alguns trabalhos nos quais foram comparadas as técnicas de enxertia, melhor pegamento com o métodos de garfagem que de borbulhia (Leite et al, 2013), conforme observado neste estudo, possivelmente em função das maiores reservas contidas nos garfos em relação às borbulhas proporcionando, com isto, maior pegamento das mudas.…”

“…O maior número de brotações foi obtido no método garfagem em fenda lateral seguido do método de Garfagem em fenda cheia, sendo superior em 71,5 % em relação aos métodos de Borbulhia em placa e Borbulhia em 'T' invertido, respectivamente (Tabela 2). Segundo Leite et al (2013) o fato se deve, provavelmente, à pouca reserva existente na borbulha, o que acarreta maior dificuldade de sobrevivência antes da união dos tecidos e, consequentemente, necessidade de um período mais longo para sua brotação. Resultados semelhantes foram obtidos por Celant et al (2010), que verificaram maior número de brotação com o método de garfagem, com incremento de 71,8% na brotação dos enxertos em comparação com a brotação da enxertia por borbulhia.…”

RESUMOObjetivou-se avaliar diferentes métodos de enxertia e o tempo de obtenção das mudas de romãzeira 'Wonderful' sob o portaenxerto 'Molar'. Utilizou-se o esquema em parcela subdividida, encontram-se na parcela os métodos de enxertia: garfagem em fenda cheia; garfagem em fenda lateral; borbulhia em placa e borbulhia em T invertido e na subparcela quatro épocas de avaliação: 45, 60, 75 e 90 dias após enxertia, no delineamento inteiramente casualizado, com quatro repetições e cinco mudas por unidade experimental. A enxertia é um método que pode ser utilizado para propagar a romãzeira 'Wonderful'. Os métodos de enxertia por garfagem proporcionou maior pegamento dos enxertos nas mudas de romãzeira. A enxertia por borbulhia em placa não é viável para a propagação da romãzeira, por proporcionar baixas percentagens de pegamento. O método de garfagem em fenda lateral proporcionaram às mudas de romãzeira, maior crescimento e acúmulo de matéria seca. Mudas de romãzeira 'Wondeful' podem ser produzidas em 75 dias utilizando-se os métodos de enxertia de garfagem em fenda cheia ou lateral.Palavras-chave: enxerto, propagação vegetativa, Punica granatum L. Growth and physiology of pomegranate nursery tree cv. wonderful propagated by graftingABSTRACT This study aimed to evaluate different methods of grafting and time of obtaining nursery of pomegranate tree 'Wonderful' under the rootstock 'Molar'. The split-plot scheme, with the grafting methods in plot: cleft grafting, side slit grafting, patch budding and inverted T budding and sub-plot four periods of evaluation, 45, 60, 75 and 90 days after grafting, in a completely randomized design, with four replications and five nursery per experimental unit was used. Grafting is a method that can be used to propagate the pomegranate tree 'Wonderful'. The methods by cleft grafting and side slit grafting showed higher budding efficiency of the nursery pomegranate tree. Grafting by budding patch is not viable for propagation of the pomegranate tree, to promote low percentages budding efficiency. The grafting method in side slit provided to the nursery of pomegranate tree greater growth and dry matter accumulation. Nursery of pomegranate tree 'Wondeful' can be produced in 75 days using the methods of cleft grafting or side slit grafting.

“…The atemoya tree (Annona squamosa L. x A. cherimola Mill.) is an interspecific hybrid originated from the cross between the cherimoya and the sugar-apple (Leite, Mendonça, Mendonça, Dantas, & Cunha, 2013). The crossing between species can occur naturally, however, the hybrid atemoya was the result of an intentional crossing, which aimed to obtain fruits with the quality presented by their parents and that presented better adaptation to the tropical climate (Rabêlo, Costa, Libório, & Almeida, 2014).…”

“…With the growing interest in the atemoya culture, safe ways to produce seedlings are essential (Leite et al, 2013), since the onegrafted can take 3 to 4 years to produce, in addition to having considerable variation on fruit quality (Almeida, Alencar, & Yamanish, 2010). For Leite et al (2013), the rootstock used in grafting is chosen due to its rusticity characteristics, availability of viable seeds, rapid development, compatibility with the graft, resistance to soil diseases and induction of good productivity.…”

Technical and secure information on the production of quality atemoya seedlings (Annona squamosa L. x Annona cherimola Mill.) are of paramount importance due to the growing interest in this crop. This study aimed to assess the formation of atemoya seedlings propagated by grafting methods and cultivars using araticum (Annona sylvatica) rootstocks. The experiment was carried out in a screened environment at the Western Paraná State University (Unioeste), Campus of Marechal Cândido Rondon, Paraná State, Brazil. Atemoya grafts (Thompson, African Pride, and Gefner) were collected from plants from the CATI seedling nursery, located in São Bento do Sapucaí, São Paulo State, Brazil. Grafting was performed using 1-year-old araticum rootstocks with 8–10 mm in diameter at a height of 15 cm from the ground and grafts measuring, on average, 8.5 cm in length, 10 mm in diameter, and three buds. The experimental design consisted of randomized blocks in a 3 × 3 factorial arrangement (three grafting methods: cleft graft, whip and tongue graft, and chip budding × three cultivars: African Pride, Thompson, and Gefner), with four replications and 10 seedlings per replication, totaling 40 seedlings per treatment. The percentage of graft success (%), percentage of sprouting (%), number of sprouts, number of leaves, and longest sprout length (cm) were assessed at 60 days after grafting. The cleft graft method is efficient for producing atemoya seedlings. The cultivar African Pride can be grafted onto rootstocks by the cleft graft and whip and tongue graft methods, as they promote a higher percentage of graft success. The Annona sylvatica rootstock has potential for the production of atemoya seedlings, but chip budding is not viable.
