| description | Vicia villosa is a potential forage resource in marginal areas associated with its natural reseeding and agronomic attributes. The objectives of this work were to record and analyze the water absorption pattern, determine the germination percentage, estimate the hydrotime parameters and establish the 13C y 15N isotopic composition of the seedling, when Vicia villosa germinates in water and salinity stress conditions. The assays to determine the water absorption pattern and the response to germination were carried out according to the treatment: control (distilled water) and the solutions with potential water (Ya): -0.3; -0.6; -0.8; -1 y -1.2 MPa. The osmolytes were poliethyleneglicol (PEG) and sodium chloride (NaCl). The isotopic composition of the total organic matter (MOT) was determined under control conditions, -0.8 and -1.0 MPa. The absorption of 125 % of water triggered germination. It was estimated that 90 % of germination would be achieved with Ya of -0.6 and -0.8 MPa in water and salinity stress. PEG and NaCl treatments showed an enrichment in 13C and a depletion in 15N with respect to the control. The experimental results lead to the conclusion that this species is more tolerant to salinity than to water stress. |

Vicia villosa es un recurso forrajero potencial en áreas marginales asociado con su resiembra natural y sus atributos agronómicos. Los objetivos del trabajo fueron registrar y analizar el patrón de absorción de agua, determinar el porcentaje de germinación, estimar los parámetros de tiempo hídrico y establecer la composición isotópica de 13C y 15N de la plántula cuando Vicia villosa germina en condiciones de estrés hídrico y salino. Los ensayos para determinar el patrón de absorción y la respuesta a la germinación se realizaron según el tratamiento: control (agua destilada) y soluciones con potencial agua (Ya): -0,3; -0,6; -0,8; -1 y -1,2 MPa. Los osmolitos fueron poliethylene glicol (PEG) y cloruro de sodio (NaCl). La composición isotópica de la materia orgánica total (MOT) se determinó en condiciones control, -0,8 y -1,0 MPa. La absorción de un 125 % de agua desencadenó la germinación. Se estimó que con Ya de -0,6 y -0,8 MPa se alcanzaría un 90 % de germinación en estrés hídrico y salino. Los tratamientos de PEG y NaCl mostraron un enriquecimiento en 13C y un empobrecimiento en 15N respecto al control. Los resultados experimentales indican que esta especie es más tolerante a la salinidad que al estrés hídrico.
