Aplicación de ácido alfa- naftalen acético en colinos de arracacha

Abstract

En las zonas colombianas productoras de arracacha el aumento en la produccion se ve limitado debido a que se da un manejo deficiente a la “semilla asexual” (colino), ya que no se realizan practicas adecuadas de seleccion, desinfeccion y enraizamiento del colino, lo cual genera poca uniformidad en el desarrollo de las plantulas y perdidas en calidad y produccion. Por lo tanto, se evaluo el efecto de la aplicacion de cuatro concentraciones de acido alfa-naftalen acetico (ANA) (0, 2, 4 y 6 mg L-1) en colinos de arracacha, en los materiales Palirrusia, Paliverde y Yema de huevo en el municipio de Boyaca, departamento de Boyaca. Se uso un diseno de bloques completamente al azar bifactorial en donde el primer factor fue el material de arracacha y el segundo factor la dosis de ANA, se aplicaron 12 tratamientos con cuatro repeticiones para un resultado de 48 unidades experimentales, empleando cinco colinos por unidad experimental, 240 colinos en total. Las variables evaluadas tiempo de emision de raices, altura de planta, longitud de raiz, masa fresca y seca de raices y numero de hojas presentaron diferencias significativas entre tratamientos. Los valores mas altos se presentaron con la aplicacion de la dosis de 2 mg L-1 de ANA en los materiales Paliverde y Yema de Huevo, mientras que para el material Palirrusia los mejores resultados se observaron con la concentracion de 4 mg L-1 de ANA. Los resultados obtenidos para los tratamientos sin aplicacion de ANA mostraron los valores mas bajos en las variables tiempo de emision de raices, masa fresca, masa seca y longitud de raiz. Palabras clave adicionales: enraizamiento, colinos, fitohormonas, Paliverde, Palirrusia.
