Efecto de la aplicación de iba sobre el enraizamiento de estacas en seis especies arbustivas nativas de la región mediterránea de chile

Abstract

Many shrubs of the arid and semiarid Chilean environments act as nurse plants on propagule recruitment. This characteristic makes them especially amenable to be used as slopes' colonists that facilitate the recruitment of herbs to form a stabilizing vegetal cover. In this context, 6 native shrubs of the mediterranean area of Chile were chosen to be used to initiate a revegetation process in slopes, through rooting of semi hard wood cuttings. 2 glasshouse trials were carried out, to evaluate the influence of commercial rooting hormone (IBA) on rooting and survival of cuttings. Escallonia illinita cuttings treated with hormone reached 73% rooting and Fabiana imbricata cuttings 79%, after 9 and 12 weeks, respectively. Both species seem to be promising to root directly on slopes during the rainfall period.
