“…The size of the canopy was slightly larger in plants multiplied from cuttings. Similar results have been observed by other authors that compared seedlings versus cuttings and/or versus micropropagated papayas [6,7,[17][18][19].…”

“…This could lead to a reduction of yield at the end of the cycle in plants propagated from cuttings [18,20], although earlier setting at a lower height favors their use since very tall papayas originating from seedlings have to be cleared from the orchard before the end of their reproductive life. Talavera et al [19] did not perceive any difference in productivity between seedlings and cuttings, while Allan [14] observed, on the contrary, higher productivity for cuttings.…”

-Introduction. Papaya is one of the very few fruit crops multiplied by seed. Unfortunately, the use of seedlings hampers the preservation of favorable plant characteristics and delays the appearance of the first flowers. In addition, the polygamous nature of papaya imposes planting 3-4 seedlings per hole in order to be certain of obtaining the right sex type. These shortcomings can be circumvented by clonal multiplication. This work aimed to multiply selected papaya cultivars from cuttings using the rooting promoting auxin indole-3-butyric acid (IBA). Materials and methods. Two experiments were conducted; the first one followed a completely randomized factorial design, with cultivars 'Golden' and 'Uenf/Caliman 01' as levels of the first factor, and 0, 500, 1,000, 1,500, and 2,000 ppm IBA as levels of the second factor. In this first trial, rooted cuttings of 'Uenf/Caliman 01' were taken to the field and compared to seedlings soon after planting and 4.5 months later. In the second experiment, IBA levels were increased aiming to enhance rooting percentage. Physiological assessments of rooted cuttings were also performed in this second experiment. Results and discussion. A concentration of 3,000 ppm IBA gave the best results for 'Golden', while lower concentration (1,500 ppm) seemed indicated for 'Uenf/Caliman 01'. Rooting success in 'Uenf/Caliman 01' was improved by using cuttings obtained from beheaded mother plants. The analyses showed that a few roots were sufficient to maintain good water status and photosynthetic rate in new plantlets. Conclusion. Plants propagated from cuttings had early flowering and produced first fruits at a lower height than seedlings in the field.

“…O desenvolvimento de mudas oriundas de diferentes métodos de propagação, em condições de campo, tem sido estudado em fruteiras como oliveira (Bati et al, 2006), pessegueiro (Marín et al, 2003), bananeira (Álvares & Caldas, 2002), mamoeiro (Talavera et al, 2009), entre outros. Na cultura do mirtilo, os resultados têm variado entre cultivares, grupos e locais de realização dos experimentos.…”

Resumo -O objetivo deste trabalho foi avaliar o desenvolvimento vegetativo e o início do período produtivo de mirtilos (Vaccinium virgatum) propagados por estaquia e micropropagação. No ano de 2009, foi implantado um pomar de mirtilo com mudas de um ano de idade, em espaçamento de 1,3x4,0 m. Utilizaram-se as cultivares Bluegem, Briteblue e Woodard, do grupo "rabbiteye". Foram avaliados os seguintes parâmetros: altura de planta, diâmetro e número de brotações, diâmetro médio dos frutos, frutos colhidos por planta, produção média por planta, produtividade estimada por hectare, massa de matéria fresca por fruto, teor de sólidos solúveis, acidez titulável e pH. Plantas obtidas pela técnica de micropropagação apresentaram maior crescimento vegetativo inicial, em razão do rejuvenescimento causado por este tipo de propagação. O método de propagação não influenciou a qualidade dos frutos. Ao contrário do esperado, as plantas micropropagadas não mostraram atraso no início da produção de frutos e apresentaram produtividade e qualidade de frutos semelhantes às de plantas propagadas por estaquia.Termos para indexação: Vaccinium virgatum, juvenilidade, produção de mudas, propagação vegetativa, rejuvenescimento. Performance of blueberry seedlings obtained by micropropagation or cuttingAbstract -The objective of this work was to evaluate the vegetative development and the onset of the productive period of blueberry (Vaccinium virgatum) seedlings obtained by semi-hardwood cuttings or micropropagation. In 2009, a blueberry orchard was established with one-year-old seedlings, at 1.3x4.0 m spacing. The cultivars Bluegem, Briteblue, and Woodard, from the rabbiteye group were utilized. The following parameters were evaluated: plant height, number and diameter of shoot, berry average diameter, number of harvested fruit per plant, average production per tree, estimated yield by hectare, fresh matter per fruit, content of soluble solids, titratable acidity and pH. Plants originated from the micropropagation technique showed high rate of initial vegetative growth, due to the rejuvenation caused by this sort of propagation. Propagation methods did not affect fruit quality. Despite the expected, micropropagated plants showed no delay in the initial fruit production and its fruit yield and quality were similar to those of cutting-propagated plants.

“…O percentual de enraizamento ficou em torno de 65%, semelhante ao verificado por outros autores que trabalharam com mamoeiro (YU et al 2000;KABIR et al, 2007;TALAVERA et al, 2009). Yu et al (2000) usaram AIB a 0,5 mg L -1 em mamoeiro 'Tainung 02' cultivado por sete dias no escuro seguido de 21 dias sob luz e, KABIR et al (2007), usaram AIB a 0,2 mg L -1 em mamoeiro 'Shahi' em cultivo sob luz.…”

“…Para o mamoeiro, no entanto, a rizogênese é um dos entraves ao processo micropropagativo (TEO; CHAN, 1994;YU et al, 2000;ROHMAN et al, 2007;TALAVERA et al, 2009;FERREIRA et al, 2011). Segundo Teo e Chan (1994), é mais fácil induzir enraizamento em culturas como cálamo, citros e gengibre do que em mamão.…”
