dc.description.abstractBackground: Patterns of seed germination and subsequent seedling growth of the endemic species Nothofagus glauca (Phil.) Krasser (Lophozonia glauca) (Hualo) were studied in two provenances from Mediterranean Central Chile (pre-Andean mountain range provenance and coastal range provenance). The main aim of the study was to determine differences in seed germination and seedling growth at the intra- and inter-provenance levels. Methods: The experiment was carried out with seeds from two provenances and four to five different sites from each provenance. Seed germination tests were conducted in 10 × 1 m beds in a greenhouse. Germinated seeds were sown in 140-mL containers and cultivated under nursery conditions for 8 months. After that period, growth and survival were measured. Results: Germination, growth and survival were highly variable at the intra-provenance level. Sites from the pre-Andean mountain range provenance exhibited lower germination capacity (33.1%) and seedling survival (76.3%) than sites from the Coastal range provenance (40.2 and 91.3%, respectively). Conclusions: Provenance variability was important for seed mass and germination, and seedling survival, while intra-provenance variability was systematically higher, whatever the functional trait considered, indicating a high potential capacity of the species to adapt to climate change. This intra-provenance variability must be conserved with the use of local seed. In our case, pre-Andean sites must be established in high-e.es_CL
