Elymus scabrifolius is a South American species, valued as a forage resource in areas with soil limitations. The objective of this study was to determine the effect of different germination temperatures on the germinative behaviour of twenty representative lines of E. scabrifolius from four different habitats. The results suggest that in E. scabrifolius the germinative behaviour can be related with provenance. The observed pattern of variation may be capitalized for future improvement programs and to determine new management rules for this species when grown in native grassland or under sown pastures
