Secondary succession is the process by which a community develops into climax over time. However, knowledge on mechanisms, relating to soil legacy effects (soil chemistry and enzyme activity) plant—soil feedback (PSF), driving remains limited. In this work, we examined PSF associated with three stage species through 2-year greenhouse experiment. Setaria viridis, Stipa bungeana, Bothriochloa isc...

El trabajo de investigación consistió en la evaluación siete especies forrajeras a diferentes edades rebrote, dos épocas del año y tres zonas agroclimáticas Costa Rica. Se utilizó un diseño tratamientos con arreglo factorial 7x2x4 (especies forrajeras, época días rebrote) 3 repeticiones, para total 168 unidades experimentales. A cada muestra se le evaluó biomasa (kg MS/ha), concentración materi...

Abstract Soluble allelochemicals have generated great interest since they can be used for the biological control of pests, especially weeds. However, few studies evaluated effectiveness soluble compounds exudates on germination in relation to exposure time. Here we evaluate inhibitory effect aqueous root, stem and leaf extracts five South American species Bothriochloa percentage seed four targe...
