Abstract
The germination capacity of Quercus pyrenaica seeds subjected to different temperatures (60°C, 100°C and 150°C for 1 and 5 minutes) and mechanical scarification was studied. Germination increased after mechanical scarification and heat treatment at 60°C for 1 minute. Germination percentages for the rest of the treatments were lower than those for the control, but statistically significant differences (p < 0.05) were only observed between 150°C for 5 minutes and the other treatments (except for 150°C for 1 minute). These results show that seed germination of Quercus pyrenaica would not be affected by soil temperatures reached during a low intensity fire or by the action of agents which can mechanically damage the external coat.
