- Abstract
The seed bank includes viable propagules present in the soil for variable periods of time, its study allows obtaining information on the richness, abundance and prediction of the presence of native species, when the area is impacted. In order to characterize the seed bank of an Amelichloa clandestina grassland in an area of 60 ha in southeastern Coahuila, 36 soil samples were collected in the 10 cm of the surface, in a quadrant of 12 × 12 cm. The samples were placed on aluminum trays and covered to prevent wind pollution. Periodic irrigation was applied. Species were counted at two-day intervals. The germination record was carried out for three months. The species richness is made up of 23 species belonging to 12 families. A. clandestina began the greatest germination after 48 days and was the species that had the highest seed germination with 1 030 (ind m-2). In the grassland there is a high reserve of seed of A. clandestina, in addition to the fact that it is the dominant species and therefore the species richness of the grassland is low.
