Abstract

ABSTRACT: Roses are considered one of the most important ornamental plants in the flower market. With this in mind, employing new productive technologies for this culture is of great scientific and economic importance. Therefore, the objective of this work was to evaluate the effect of different concentrations of BAP cytokinin on the induction of shoots in Rosa sp. in vitro. Nodal segments containing axillary buds of a commercial matrix of Rosa sp. were supplemented with various concentrations of BAP (0.0, 0.25, 0.5, 1.0, 1.5 mg / L). The highest rates of responsive explants (which had buds) were obtained at the highest concentrations of BAP hormone, although there was no significant statistical difference at 5% between treatments. Therefore, the variation of the BAP concentration influenced the number of explants established in vitro, providing greater survival and sprouting in the nodal segments of Rosa sp.KEYWORDS: Micropropagation, Rose, Tissue culture.
