Název v původním jazyce

First record of Potamogeton x salicifolius for Italy, with isozyme evidence for plants collected in Italy and Sweden

Popis výsledku v původním jazyce

Potamogeton x salicifolius, a hybrid between P. lucens and P. perfoliatus, was identified as a new taxon for Italy. This is the first record of this hybrid from southern Europe. The Italian sample was studied in cultivation and compared with a living specimen of P. x salicifolius from Sweden, where the hybrid is rather widespread. In addition to morphological features, the most compelling evidence for the hybrid origin of these plants came from the isozyme analysis. The additive "hybrid" banding patterns of the five enzyme systems studied indicate inheritance from P. lucens and P. perfoliatus. The distribution of this hybrid in Europe coincides with the areas most severely affected by the Late Pleistocene glaciation. The relationships between environmental conditions, history of the habitat and rise of hybrids are discussed.
