| description | Colombia is the fourth largest producer of plantain in the world, with a harvest of 3,539,252 t. Various biotic and abiotic factors affect yields, including phytoparasitic nematodes that are a major constraint in this crop. For this reason, strategies are being sought to improve the performance of this plant with this cosmopolitan pest. This research evaluated the effect of two hormonal regulators on the growth and development of the Dominico plantain. The experiment design had treatments that were divided plots, where the main plot corresponded to the type of product, and the sub-plot corresponded to the concentrations of paclobutrazol and mepiquat chloride in the different doses: 0, 250 and 500 mg L-1. The experiment unit consisted of ten plants with four replicates. The evaluated variables were plant height, diameter of the pseudostem, number of functional leaves, length and diameter of the roots, number of nematodes and variables for production quality. The two growth regulators reduced the plant height before emergence of the flower; paclobutrazol reduced the height by up to 40%, while mepiquat chloride reduced the height by up to 6.7%. There were no statistical differences in the production per plant, where the production with paclobutrazol was 14 kg/plant and, with mepiquat chloride, was 15 kg/plant. The control was 14.5 kg/plant. The use of growth regulators did not significantly restrict the damage caused by nematodes; however, paclobutrazol performed better as a growth regulator in the Dominico Hartón plants. |

Colombia es el cuarto productor mundial de plátano con una cosecha de 3.539.252 t. Diversos factores bióticos y abióticos afectan a los rendimientos, siendo los nematodos fitoparásitos una de las principales limitaciones de este cultivo. Por esta razón, actualmente se están buscando estrategias para mejorar el rendimiento de esta planta con esta plaga cosmopolita. Esta investigación evalúa el efecto de dos reguladores hormonales en el crecimiento y desarrollo del plátano Dominico. El diseño experimental de los tratamientos se realizó en parcelas divididas, donde la parcela principal corresponde al tipo de producto, y la subparcela a las concentraciones de paclobutrazol y cloruro de mepiquat a diferentes dosis: 0, 250 y 500 mg L-1, respectivamente. La unidad experimental constaba de diez plantas con cuatro réplicas. Las variables evaluadas fueron la altura de la planta, el diámetro del pseudotallo, el número de hojas funcionales, la longitud y el diámetro de las raíces, el número de nematodos y las variables de calidad de la producción. Los dos reguladores del crecimiento muestran una reducción de la altura de la planta antes de la emergencia de la flor, el paclobutrazol reduce la altura hasta un 40%, mientras que el cloruro de mepiquat reduce la altura hasta un 6,7%. No hay diferencias estadísticas en la producción por planta, la producción con paclobutrazol fue de 14 kg/planta, el cloruro mepiquat 15 kg/planta y el control con 14,5 kg/planta. El uso de reguladores de crecimiento no restringe significativamente el daño causado por los nemátodos, sin embargo, el paclobutrazol muestra un mejor desempeño como regulador de crecimiento en las plantas de Dominico Hartón.
