“…Vários autores comprovaram, em campo, que mudas de mirtilo propagadas in vitro apresentam maior número de brotações do que as propagadas por estaquia (Read et al, 1989;Jamieson & Nickerson, 2003;Litwinczuk et al, 2005). A emissão de maior número de brotações oriundas do colo da planta possibilita renovação das hastes produtivas, já que o mirtilo apresenta hábito basitônico, ou seja, suas brotações surgem da base da planta.…”

“…A cultivar Bluegem foi a de menor diâmetro. As cultivares Bluegem e Woodard se destacaram quanto à produção por planta e por área, tendo atingido valores tidos como adequados (Read et al, 1989), considerando-se que esta foi a primeira colheita. Os menores índices de produtividade para 'Briteblue' se devem a problemas de ordem fitossanitária, como a seca dos ramos ("stem blight"), causada por Botryosphaeria spp.. Antunes et al (2008) constataram produção de 1,5, 1,63 e 0,67 kg por planta, respectivamente, para as cultivares Bluegem, Briteblue e Woodard, oriundas de estaquia.…”

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.

“…In a field trial, Dweikat and Lyrene (1988) found no off-types among young blueberry (V. corymbosum × V. Elliottii) plants obtained from adventitious shoots but this study did not evaluate fruit characteristics as the examined plants were only several months old. Although Grout et al (1986) reported more basal branches and lateral shoots on micropropagated plants of highbush blueberry than on those propagated by stem cuttings, and Read et al (1988) obtained more flower buds and higher yields on micropropagated highbush blueberry cultivars, micropropagated lowbush blueberries produced fewer flower buds than did conventionally propagated plants (Jamieson and Nickerson 2003). Softwood cutting-derived Herbert highbush blueberry plants grew more slowly and produced less and shorter shoots than did micropropagated plants, although majority of the cutting-propagated plants developed flowers more abundantly and earlier, and bore larger berries than did the plants from tissue culture (Litwińczuk et al 2005).…”

Debnath, S. C. 2007. Strategies to propagate Vaccinium nuclear stocks for the Canadian berry industry. Can. J. Plant Sci. 87: 911-922. Vacinium fruits are genetically heterozygous species characterized as "not coming true from seed". Conventional methods for vegetative propagation of these species, although successful, are slow and labour-intensive, and few propagules can be produced from one plant of a selected clone or hybrid. Micropropagation techniques are important for clonal multiplication, germplasm improvement and gene conservation of Vaccinium fruits cultivated in Canada including blueberries, cranberries and lingonberries. In vitro propagation of these species using axillary bud proliferation and adventitious shoot regeneration has been investigated in a number of studies. Morphogenesis seems to be highly dependent on plant growth regulators and media used for culture, and this dependence is genotype specific. The paper presents the progress in-depth of various aspects of the in vitro culture of Canadian Vaccinium species for their commercial production. Also discussed are techniques for clone rejuvenation and plant tissue culture for mass propagation of Canadian Vaccinium nuclear stocks. Les techniques de multiplication végétative in vitro revê-tent une grande importance pour la multiplication des clones, l'amélioration du matériel génétique et la conservation des gènes des fruits du genre Vaccinium cultivés au Canada, notamment le bleuet, la canneberge et l'airelle vigne-d'Ida. Diverses études se sont penchées sur la multiplication in vitro de ces espèces par prolifération des bourgeons et régénération des pousses adventives. La morphogénèse semble considérablement dépendre des régulateurs de croissance de la plante et du milieu de culture, une dépen-dance propre au génotype. L'article fait le point des progrès réalisés au niveau des divers aspects de la culture in vitro des espèces canadiennes du genre Vaccinium en vue de leur culture commerciale. On y présente aussi les techniques de rajeunissement des clones et de culture tissulaire pour la multiplication massive du matériel génétique des espèces canadiennes de Vaccinium.

“…Micropropagation is nowadays the most popular method being the most efficient relative to other techniques, and providing healthy and uniform planting material. The supportes of this method are convinced that blueberry shrubs from the in vitro cultures grow more vigorously [Read et al 1989, ElShiekh et al 1996. There are as well the oponents who think that even if initialy shrubs grow strong they start cropping later and their fruits are smaller as compared to the traditionally propagated plants [Litwińczuk et al 2005, Ostrolucká et al 2007].…”

During plant propagation changes in genetic stability may occur, not only during the in vitro multiplication but also in the ex vitro conditions in response to the sum of stress factors affecting plants. It is therefore necessary to evaluate planting material in terms of its genetic stability. The aim of the work was to assess by the RAPD method genetic stability of the ex vitro rooted blueberry (Vaccinium corymbosum 'Bluecrop' and 'Duke') microcuttings. Also an effect of biostimulator Goteo (0.2%) on rhizogenesis was tested as compared to the auxin indole-3-butyric acid IBA (50 mg·l -1 ) applied as water solution and a commercial rooting powder Rhizopon AA containing 1% IBA. All the rooting stimulators improved the percentage and degree of rooting in blueberry microcuttings. The biostimulator gave results only slightly poorer than the auxin. Both cultivars were genetically stable and no DNA polymorphism was found between the traditionally propagated stock plants growing in a nursery and those rooted in vivo, regardless of the rooting enhancer used.
