Comparacion de la viabilidad de las semillas obtenidas por medio de las tecnicas de extraccion fisica por lavado y de germinacion

Abstract: RESUMEN -El objetivo del presente trabajo fue comparar la viabilidad obtenida por la técnica de viabilidad por presión (VPP) respecto de la viabilidad obtenida por una combinación de la metodología VPP más germinación. Asimismo se trató de establecer si ambos procedimientos determinan la viabilidad de las mismas especies o si existen diferencias en las especies establecidas como viables. El número de semillas viables estimado por la técnica VPP fue de 3475 (9,85% del total del banco de semillas), en tanto el n… Show more

“…Seeds from the three species were collected randomly from several individuals in FebruaryeMarch 2007 and stored in paper bags at room temperature until the experiments were performed. We selected the viable seeds using the pressure method (Zuluaga et al, 2004) for Festuca and Rumex seeds, and the flotation method for Pappostipa seeds. In October 2007, we sowed seeds from each species in trays (one seed per 150 cm 3 tray) with grassland soil that was previously sterilized (2 days at 100 C) to kill the soil seed bank.…”
