摘要：
A study was carried out on the effect of a fire on the seed bank of a Quercus faginea forest situated close to the town of Palencia (NW Spain). Soil samples were taken at two depths: upper layer at 0-2 cm and deeper at 2-5 cm, in a burned area and in one nearby which did not suffer from the fire. The specific richness values, obtained 2 years after the fire, in samplings carried out in the field as well as the soil seed bank were higher in the burned area than the control. The number of germinated seeds was also higher in the burnt area than the control and more abundant in the surface stratum than the deeper one in both areas. In the control area the richness was 33 species, while in the burned area the richness was greater by five species. On the other hand, the cover value was 58 % in the burned area and 61 % in the control area. ((C) Inra/Elsevier, Paris.).
