Abstract

The aim of this paper is to determine the effect of the morphotype constraints and the provenance of Quercus coccifera L. acorns on the germination success. The selected two areas of provenance in the Alicante province (Spain) that have been analysed in this study differ in their environmental conditions and geographical origin: a semiarid area with an average precipitation of 271 mm. and a subhumid area with an average precipitation of 833 mm. The morphotypes analysed in this research have been selected according to the size of the leaves of individuals of populations growing in a semiarid area, for this morphological trait may well be an adaptive response to a particular environment. Our hypothesis is that the adaptive response of plants to different environments can result in significantly different morphological and physiological behaviours, which will in turn have an effect on the germination process. The results suggest that the germination success of acorns produced by different morphotypes vary from one population to another, whereas the effect of the provenance factor depends on the morphotype. Altogether, the evidence of this study can help identify the populations or individuals whose seeds are more likely to germinate successfully, this being an essential preliminary step to the restoration of degraded areas.
