    Actas del seminario regional: avances en la investigación de Acacia saligna, como opción productiva para la IV Región
    Los principales objetivos que se logró satisfacer con la realización del Seminario fue el promover la interacción entre los investigadores e informar al medio nacional sobre la contribución en el desarrollo de la actividad rural de la región de Coquimbo del proyecto "Acacia saligna, una especie multipropósit como alternativa silvopastoral para la optimización del D.L 701 en la IV Región", llevado a cabo por el Instituto Forestal y financiado por el Fondo de Desarrollo e Innovación de CORFO. El presente documento corresponde a un resumen de las actas del seminario regional, que contempla las principales investigaciones realizadas durante el desarrollo del proyecto.

    Fall fertilization during nursery production increases nitrogen status of Purshia tridentata seedlings: implications for outplanting
    During container nursery production of Purshia tridentata (antelope bitterbrush), we found that three fall fertilization applications successfully loaded plants with nitrogen (N) with little effect on plant biomass. Using 15N-labeled fertilizer to track N movements, we observed that N-loaded seedlings attained luxury consumption and ultimately translocated more N toward roots. In trees, such N-loading efforts have been reported to increase seedling survival and growth after outplanting by improving initial root growth. This leads to enhanced access to water and nutrients that increases overall plant competitiveness and performance. Our results add, in general, to the paucity of information concerning fall fertilization of shrubs, and specifically that this technique offers promise to enhance the quality of antelope bitterbrush seedlings. This could improve overall planting success of this important shrub native to western United States rangelands. Increasing the effectiveness of planting antelope bitterbrush, which can often improve restoration trajectories more than direct seeding or reliance on natural regeneration of this species, could accelerate the pace and scope of critical habitat restoration. Restoration is needed as antelope bitterbrush abundance has been reduced across the landscape because of conversion to agriculture, invasion by nonnative annual grasses, and an increase in fire frequency and intensity, among other reasons. In addition, this species provides browse for ungulates and critical habitat for at-risk species, such as Centrocercus urophasianus (greater sage-grouse). Although N loading antelope bitterbrush has potential to improve outplanting performance, the resulting higher nutrient status of this preferred browse species may lead to elevated browsing during seedling establishment.
