Abstract

SOLORZA-BEJARANO, Jairo Hernán. Regeneration pattern of the seedling of Genista monspessulana (L.) L.A.S. Johnson, in two ecological restoration scenarios. Colomb. for. [online]. 2017, vol.20, n.2, pp.131-143. ISSN 0120-0739.  https://doi.org/10.14483/udistrital.jour.colomb.for.2017.2.a03.

In order to improve the control programs of the invasive species Genista monspessulana, in two scenarios of ecological restoration with different light availability in Bogotá, we analyzed the seed bank regeneration pattern and the initial development of the individuals. For that, coverage, abundance, height, epigeal and hypogeal length, number of leaflets, leaf area, root diameter, number of root branches, presence of nodules and biomass epigeal and hypogeal of ​​the seedlings were studied. Seedling development as well as seedbank regeneration showed differences in the ecological scenarios. In the area under tree canopy, individuals presented slow growth, limited by litter cover and low light availability, while in the open area with greater light incidence, the individuals showed a rapid development of the leaves and roots, in addition of the mutualistic association with microorganisms that allows them greater absorption and fixation of nitrogen.
