Abstract

The chemical and physical properties of the substrate produce positive or negative effects on the germination of seeds, and different pre-germination treatments are applied to obtain better results. However, the use of soil as a substrate where the species grows is usually not evaluated or used as a treatment. The objective of the present study was to evaluate the effect of the native substrate [two types of substrate where the woody species grow (clay and sand)] on the germination of Acacia farnesiana, Larrea tridentata and Prosopis laevigata. In addition, two groups were compared in seeds (grouped and not grouped) of the protected area "Parque Estatal Cañón de Fernández". The results showed that the seed grouping reduced germination in the evaluated species, while the germination rate was only affected in Prosopis laevigata in the evaluated substrates.
