Enraizamiento de esquejes apicales de madroño mediante reguladores del crecimiento

Abstract

Arbutus unedo L. (madroño), arbusto esclerófilo ampliamente distribuido por el área mediterránea, es considerado como una especie interesante para jardinería y paisajismo, principalmente por su buen comportamiento en condiciones de estrés hídrico, calor y baja humedad ambiental y por su gran valor ornamental. Esta especie ha mostrado una baja capacidad de enraizamiento en la propagación vegetativa. Se investigó el efecto de la aplicación de ácido indolbutírico (AIB) y de paclobutrazol (PBZ) en el enraizamiento de esquejes de madroño. Los esquejes se cortaron de la porción apical de los tallos en crecimiento (y floración). Se utilizaron diversas soluciones acuosas de AIB (0, 1000, 2000, 4000 y 8000 ppm) y de PBZ (0, 1000, 2000, 4000 y 8000 ppm). No se produjo enraizamiento en ausencia de tratamiento hormonal (control). La aplicación de AIB aumentó significativamente los porcentajes de enraizamiento y la calidad del enraizamiento respecto a los controles, incrementando el número de raíces, su longitud total, el grado de ramificación y el peso seco radicular. Contrariamente, el PBZ no tuvo efecto sobre la promoción de raíces en los esquejes apicales de madroño.
