Description
Summary:We evaluated the environmental adaptability of Lavandula multifida L., a plant species presents in the Western Mediterranean Basin with a threatened peripheral population in Southern Italy. Germination capacity, activities of some hydrolyzing enzymes associated with germination and antioxidative pathway of Calabrian L. multifida were quantified in comparison with a Spanish core population. The Calabrian population showed a lower germination ability and it can be related to the small size of the population and associated inbreeding depression. Difference between two populations in enzymatic assays and antioxidative pattern during germination and early seedling development may in part explain a different ability of these two populations to respond to external cues and a diverse environmental adaptability. The study on germination strategies of isolated populations is important to define possible programmes to preserve genetic biodiversity of autochthon plants populations.
