Propagación de Erato polymnioides bajo distintas concentraciones de suelo y condiciones de manejo

Abstract

Abstract: Erato polymnioides is a hyperaccumulating species of heavy metals, which is why it can be used in bioremediation projects in mining areas. However, it is not known about its propagation processes, so it was proposed to identify the optimal conditions for the propagation of E. polymnioides under greenhouse conditions. To fulfill the objective, two trials were carried out, the first consisted of eight treatments based on four kinds of substrates and two concentrations of hormones applied in stakes; and the second consists of four treatments based on two kinds of substrates, planting seedlings, grouped and ungrouped. The highest formation of shoots, leaves and root growth in cuttings, occurred in the treatment that contained soil from the site where the species develops, with and without paclobutrazol, while for the association of seedlings the best treatment was that It consisted of fertilizer / peat, with association of three seedlings. The results show that the species develops better on substrates prepared in early stages, while stakes are better suited to substrates containing clay.
