Promotores de crecimiento radical en el cultivo de plátano (musa aab cv.) “hartón” en fase de vivero.

Abstract

The objective of this research was to evaluate the influence of three doses of cytokinins as promoters of the radical development of the plantain crop (Musa AAB cv.) Hartón in the nursery phase in El Carmen, Manabí. Three doses of cytokinins were used (High: 2.75 - Medium: 2.00 - Low: 1.25 cc L -1 of water), applied to corms arranged in a randomized complete block experimental design (DBCA), with three treatments plus a control and three repetitions. It was established that there was no inference of the different doses of cytokinin evaluated on the agronomic behavior of Hartón plantain in the nursery phase; it was identified that the low dose of cytokinins improved root development at the dry matter level with 10.27%. It will be prolonged that there was an effect of cytokinins on macronutrients at the radical level, specifically in the nitrogen content with high and low doses (1.53%) and for sulfur the low dose was the best (0,060%); In addition, the same low dose influenced the content of micronutrients in roots, specifically copper (22 ppm), iron (215 ppm) and manganese (37 ppm).
