“…The results obtained in particular for the Powderblue cultivar are superior to the work carried out by Colombo et al, (2018) which obtained a variable of 3.5 to 5 roots per mini-cuttings to cultivate Powderblue, when cultivated on different substrates (rice husks carbonized, pine bark and vermiculite) submitted to 3.000 mg.L -1 of IBA. This difference is probably due to the relationship between the different dosages of IBA or the physical characteristics of the substrate used, which emphasizes the importance of the material to be used.…”

The objective of this work was to evaluate the rooting of semi-hardwood blueberry minicuttings, from different cultivars and groups, from the Highbush and Rabbiteye groups in the same culture medium. The experiment was carried out in an agricultural greenhouse in a commercial nursery whith semi-hardwood mini-cuttings were used. The work was conducted, with cuttings segmented into mini-cuttings with three gems and an average diameter of 1.5 mm. Subsequently, their bases were immersed, for 10 seconds, in a commercial solution of IBA, in the concentration of 2.000 mg.L-1, with a mixture of coarse-grained sand and commercial substrate in the proportion of 1:1 as a substrate. The Bifactorial experimental design used was in completely randomized blocks, with two groups (highbush and rabbiteye) and six cultivars (Georgiagem, Misty, O'Neal, Bluegem, Powderblue and Woodard), with four replications and ten cuttings per plot. The percentage of rooted cuttings and surviving cuttings, average number of roots and shoots per cuttings, length of the largest root and shoot, were evaluated. It was found that, in general, the rabbiteye group was superior when compared to the highbush group. Blueberry cultivars from the rabbiteye group when propagated by semi-hardwood cuttings, have greater rooting facility than cultivars from the highbush group. The rooting potential between the cultivars in blueberry studied was different, allow the formation of 95% of cuttings rooted in 90 days.

“…The hydroalcoholic solution of IBA was prepared according to Colombo et al (2018), in which 0.1 g of IBA was weighed and dissolved in 50 mL alcohol. After completely dissolving the IBA, the volume was made up to 100 mL with distilled water, giving the concentration of 1,000 mg L -1 .…”

The objective of this work was to evaluate the rooting of herbaceous cuttings of CAMB-06 and APU-04 acerola cherry selections associated with the use of indolebutyric acid (IBA) and a concentration of aqueous extract of coco-grass. Cuttings were treated by immersion with different concentrations of IBA (0; 1,000; 2,000; 3,000; 4,000 mg L -1 ) and one application of aqueous extract of coco-grass in proportion 100% and placed to root in plastic boxes containing vermiculite. The experimental design was a completely randomized in a 2×6 factorial arrangement (two acerola cherry selections and six solutions for rooting) with four replicates of ten cuttings. After 90 days of cutting, the following variables were evaluated: cutting survival (%); leaf retention (%); rooted cuttings (%); sprouting (%); number of roots per cutting (%); length of roots (cm) and dry mass of roots per cutting (g). It was concluded that the application of IBA at 4,000 mg L -1 presented a better root development, resulting in a higher percentage of rooted cuttings and higher number and dry mass of roots in relation to IBA at 0 mg L -1 for CAMB-06 selection, while the APU-04 selection can be efficiently multiplied by herbaceous cuttings without the use of IBA. Under the conditions that the trials was conducted, the application of 100% aqueous extract of coco-grass was not effective in promoting the rooting of cuttings of CAMB-06 and APU-04 acerola cherry selections. Enraizamento de estacas deMalpighia emarginata D.C. (seleções CAMB-06 e APU-04) associadas ao uso do ácido indolbutírico e extrato aquoso de Cyperus rotundus L.Resumo -O objetivo deste trabalho foi avaliar o enraizamento de estacas herbáceas das seleções de acerolas CAMB-06 e APU-04 associadas ao uso de ácido indolbutírico (AIB) e uma concentração de extrato aquoso de tiririca. As estacas foram tratadas por imersão com diferentes concentrações de AIB (0; 1.000; 2.000; 3.000 e 4.000 mg L -1 ) e uma aplicação de extrato aquoso de tiririca, na proporção 100%, e dispostas para enraizar em caixas plásticas contendo vermiculita. O delineamento experimental foi inteiramente casualizado, em arranjo fatorial 2×6 (duas seleções e seis soluções para enraizamento) com quatro repetições de dez estacas. Após 90 dias da estaquia, foram avaliadas: sobrevivência das estacas (%); retenção foliar (%); estacas enraizadas (%); brotação (%); número de raízes por estaca (%); comprimento de raízes (cm) e massa seca de raízes por estaca (g). Concluiu-se que a aplicação de AIB na concentração 4.000 mg L -1 apresentou melhor desenvolvimento radicial, resultando em maior porcentagem de estacas enraizadas e maior número e massa seca de raízes em relação à concentração 0 mg L -1 de AIB para a seleção CAMB-06, enquanto a seleção APU-04 pode ser propagada por estaquia herbácea com eficiência, sem o uso de AIB. Nas condições em que o experimento foi conduzido, a aplicação de 100% de extrato aquoso de tiririca não foi efetiva na promoção do enraizamento de estacas das seleções de acerola CAMB-06 e APU-04.

“…The different results recorded by some authors for the same cultivar may be related to the use of plant regulators (type, concentration, and application methods), collection season and vegetative stage of the parent plants, substrates (since different materials have different physicochemical properties), and period to access rooting performance (Colombo et al, 2018). Therefore, it is necessary to evaluate each one of the factors to enable the multiplication of the blueberry, a species considered difficult to propagate.…”

Plant regulators used alone or associated with rhizobacteria are alternatives that maximize the rhizogenic potential of cuttings that are difficult to root, such as the blueberry. Thus, the objective of this study was to investigate if concentrations of IBA in talc, associated or not with the rhizobacteria Azospirillum brasilense and Bacillus subtilis, interfere in the viability of blueberry mini cuttings, cultivar 'Brite Blue'. The experimental design used was entirely randomized, with four repetitions. The treatments studied, designed in a bifatorial scheme (4 × 3), were concentrations of IBA (0, 500, 1,000, and 2,000 mg L -1 ), applied as talc, associated or not with A. brasilense and B. subtilis. A significant interaction was observed between the factors IBA and inoculation with rhizobacteria regarding the presence of callus. In relation to the isolated effect of inoculation, B. subtilis proved to be superior to the treatments with application of IBA alone, also presenting the highest percentage of sprouted minestems. There was an isolated effect of IBA doses on the number of roots per minicutting, survival, and rooted minicutting. It is concluded that the treatments with IBA and rhizobacteria, especially B. subtilis, favor the viability of the 'Brite Blue' minicuttings.
