“…In both experiments, the percentage of sprouting cuttings was around 50-60% when cultivated in pine bark substrate. For Vaccinium ashei 'Climax' and Vaccinium ashei 'Florida' blueberries, the sprouting cuttings percentage was close to 50%, regardless IBA concentration and application methods (Peña et al, 2012).…”

“…The rooting percentage of 'Climax' blueberry cuttings ranged from 34.6 to 50.6% in experiments carried out by Hoffmann et al (1995) and Peña et al (2012), respectively; and according to Peña et al (2012) the differences observed are due to the period that the rooting was accessed. However, for the same cultivar, regardless the IBA use, 19 and 82% of rooting was recorded by Trevisan et al (2008) and Fischer et al (2008), respectively.…”

The nursery plants supply is one of the most important factors that limites blueberries production in some areas, due to some propagation difficulties observed on this species. In this way, this study aimed to evaluate substrates and IBA application methods on 'Powderblue' blueberries (Vaccinium ashei) minicuttings rooting, as well as to verify the rooting development in different periods. The study was divided in two experiments. The first one aimed to evaluate 'Powderblue' blueberry minicuttings rooting in three substrates (pine bark, carbonized rice husk and vermiculite) in response to two indolebutyric acid (IBA) application methods: 50% alcohol solution and talc. The second experiment aimed to evaluate 'Powderblue' blueberry minicuttings rooting using the best substrate recorded in the first trial (pine bark) and two IBA application methods associated to three periods of rooting access, in order to obtain the ideal rooting period and root development. In the first experiment the rooting percentage presented significant difference among the substrates; the higher percentage of rooted minicuttings occurred in pine bark substrate (68%). Regarding the methods used to IBA application, the talc method was more efficient to promote minicuttings rooting. In the second experiment, it was observed an increase in cutting rooting percentage from 55 to 84%, according to the evaluated seasons; however, the IBA application method did not influence the rooting percentage. Therefore, to produce 'Powderblue' blueberry plants from minicuttings it is recommended to use pine bark as substrate and talc as method to IBA application, transplanting the nurseries at 110 days after planting.

“…O efeito positivo da aplicação de AIB também foi observado por Fischer et al (2008b), na cultivar Powderblue, e a concentração de 1.000 mg L -1 foi a mais favorável. O efeito benéfico da aplicação de AIB no enraizamento de estacas de mirtilo também foi verificado para outras cultivares, como Florida e Climax, na estaquia realizada no final do verão (Peña et al, 2012), e Delite na estaquia de inverno (Fischer et al, 2008b). A obtenção de regressões lineares, no presente trabalho, é um indicativo de que maiores percentagens de enraizamento podem ser obtidas com maiores concentrações de AIB.…”

“…A produção comercial de mudas é basicamente obtida pela estaquia. Entretanto, os resultados dessa técnica variam de acordo com a cultivar (Fischer et al, 2008a(Fischer et al, , 2008bTrevisan et al, 2008;Peña et al, 2012) e com as condições ambientais de cada viveiro (Piller et al, 2002).…”

Resumo -O objetivo deste trabalho foi avaliar os efeitos da aplicação de concentrações do ácido indolbutírico (AIB) e do aquecimento do substrato sobre o enraizamento de estacas caulinares das cultivares de mirtilo Bluebelle, Bluegem e Powderblue, nas quatro estações do ano. Utilizou-se o delineamento experimental inteiramente casualizado, com arranjo fatorial 4x5x2 (estações x concentrações de AIB x com e sem aquecimento do substrato), com 4 repetições e 20 estacas como unidade experimental. Foram avaliadas as percentagens de estacas enraizadas, mortas, vivas e com calo, e o número e o comprimento médio de raízes. As maiores percentagens de enraizamento foram 57,1% na 'Bluegem', no verão, 30% na 'Bluebelle', na primavera, com aquecimento, e 63% na 'Powderblue', no verão, com aquecimento. O AIB na concentração de 2.000 mg L -1 aumentou o enraizamento de estacas das cultivares Bluegem e Powderblue. O aquecimento do substrato melhora o enraizamento das estacas coletadas no outono e no inverno, em todas as cultivares e, também, das estacas coletadas no verão e na primavera, na cultivar Bluebelle.Termos para indexação: Vaccinium ashei, auxina, enraizamento, propagação vegetativa. Cutting propagation of blueberry in seasons of the year with indolebutyric acid and bottom heatAbstract -The objective of this work was to evaluate the effects of the application of concentrations of indolebutyric acid (IBA) and of bottom heat on rooting of stem cuttings of the blueberry cultivars Bluebelle, Bluegem, and Powderblue in the four seasons of the year. A completely randomized design was used, with a 4x5x2 factorial arrangement (seasons x concentrations of IBA x with and without heat), with 4 replicates and 20 stem cuttings as an experimental unit. The percentage of rooted cuttings, dead, alive and with callus, and the number and average length of the roots were evaluated. The highest rooting percentages were 57.1% for 'Bluegem' in summer, 30% for 'Bluebelle' in spring, with heating, and 63% for 'Powderblue' in summer with heating. IBA at the concentration of 2,000 mg L -1 increased the rooting of cuttings of the cultivars Bluegem and 'Powderblue'. Bottom heat increases the rooting of the cuttings harvested during autumn and winter in all cultivars, and also the cuttings harvested during summer and spring in the Bluebelle cultivar.

ResumoO presente trabalho estudou a necessidade do uso da auxina exógena Ácidoindol-butirico (AIB) no enraizamento de estacas caulinares da Varronia curassavica Jacq. O experimento foi conduzido em casa-de-vegetação com controle parcial de temperatura e umidade, na área experimental do setor de Olericultura do Instituto Federal de Educação, Ciência e Tecnologia do Triângulo Mineiro (IFTM) em Uberaba, MG. Avaliaram-se os efeitos de diferentes doses do AIB no processo de enraizamento de estacas de erva baleeira (0, 200, 400, 600, 800 e 1000 mg L -1 ), posteriormente plantadas em tubetes contendo mistura de areia e vermiculita na casa-de-vegetação. O delineamento experimental utilizado foi o em bloco casualizados, com seis tratamentos quantitativos e quatro repetições, totalizando 24 unidades experimentais. Após 65 dias, avaliou-se o enraizamento pelo índice de sobrevivência das estacas e a análise estatística foi feita através de análise de regressão. A análise nos mostra que o hormônio AIB exerce influência significativa sobre a porcentagem de plantas sobreviventes. A melhor dose do hormônio AIB para o enraizamento de estacas de erva baleeira, em relação ao maior numero de estacas brotadas, foi de 223 mg L -1 , ajustando-se o modelo de grau 2. Conclui-se que pode ser realizado um eficiente enraizamento da erva baleeira com dose de 223 mg L -1 de AIB, em condições ambientais semicontroladas. Palavras chave: auxina exógena, ácido indolbutírico, erva baleeira Adventitious rooting of cuttings of Varronia curassavica Jacq. with use of indol butyric acid AbstractThis work studied the need for the use of exogenous auxinindole-butyl acid (IBA) on rooting cuttings of Varronia curassavica Jacq. The experiment was conducted in a greenhouse, with partial control of temperature and humidity in the experimental area of Horticultural sector of the Federal Institute of Education, Science and Technology (IFTM) in Uberaba, MG, Brazil. It has been evaluated the effects of different AIB doses in the rooting process of cuttings (0, 200, 400, 600, 800 e 1000 mg L -1 ), then planted in plastic tubes containing a mixture of sand and vermiculite in-house-vegetation. The experimental design was a randomized block with six quantitative treatments and four replications, totaling 24 experimental units. After 65 days, were evaluated the rooting by the survival rate of cuttings and statistical analysis was performed using regression analysis. The best dose of IBA hormone for rooting cuttings, for the largest number of sprouting, was 223 mg L -1 , by adjusting the degree of model 2. For other doses, do not differ significantly from the control. It is concluded that can be carried out efficiently rooting of the Varronia curassavica Jacq. at a dose of 223 mg L -1 IBA, in semi controlled environmental conditions.
