MARTINS-VERAS, MÁRIO LENO et al. Rooting of yellow mombin cuttings (Spondias mombin L.) as a function of the application of plant regulators. rev.colomb.cienc.hortic. [online]. 2018, vol.12, n.3, pp.574-581. ISSN 2011-2173.  https://doi.org/10.17584/rcch.2018vl2i3.8055.

At the moment, there are no commercial yellow mombin crops in Brazil, where fruits are harvested from extractive crops. One reason for this is the lack of a propagation protocol for this species because the yellow mombin has a low rooting percentage for cuttings. Therefore, techniques that provide maximum rooting for cuttings are required. The objective of this study was to evaluate the effect of a matrix plant treatment with zinc on the rooting of yellow mombin cuttings treated with indolebutyric acid. In this experiment, a completely randomized design was used, with 9 treatments arranged with pre-determined levels for the factors with the matrix "Central Box Compound" for the zinc concentrations (0, 5.8, 20, 34.2 and 40 mg L-1) and combinations with the indolbultric acid concentrations (0; 872.35; 3,000; 5,127.65 and 6,000 mg L-1), with 4 replicates, where each experiment unit consisted of 12 cuttings. The application of zinc in yellow mombin matrix plants had no effect on the rooting of cuttings. The 6,000 mg L-1 indolebutyric acid dose provided an increase in sprouts and live cuttings with a callus; however, it did not influence the rooting.
