Association of indolebutyric acid with rhizobacteria on the viability of herbaceous minicuttings of blueberry ‘Brite Blue’

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