Germinación y crecimiento de Vicia magellanica: Implicancias para la restauración de áreas incendiadas en el norte de la Patagonia andina

Knowing the regeneration dynamics of pioneer species after fires is essential to design tools for protection and restoration environments degraded by fire. Autoecology studies native can contribute with valuable information planning land management passive and/or active actions. We conducted essays seed germination plant growth (utilizing burned soils without incorporation compost) purpose a) identifying factors associated fire that could be related post-fire patterns Vicia magellanica (Fabaceae), and, as well, b) discussing potential role this in areas northwest Patagonia. In general, percentages exceeded 90% total almost all treatments (control, application ashes, physical scarification, cold stratification). However, exposition seeds dry heat, elevated soil temperatures during occurrence (100 °C 120 °C), showed a negative effect on germination. The results experiment evaluating performance V. possible scenario edaphic conditions burnt allowed satisfactory development individuals. Plants growing biosolids compost presented higher aboveground belowground biomass number flowers, comparison plants compost. These characteristics might confer an advantage colonizing soils. presents several properties support use revegetation strategies forest shrublands Patagonia, principally applying direct sowing field, particularly early stages.
