[en] Posidonia oceanica is a magniolophyte endemic to the Mediterranean Sea, in which flowering can vary depending on water
temperature and nutrient concentration (C,N,P). Along corsican coast, in the Northwestern Mediterranean Sea, the flowering was
unusual but in the last 20 years it flowered regularly. The aim of our study was to determine the effect of the frequency of
flowering episode on the shoots by measuring the dynamics of elementary (C, N, P) and the trace element contents (TE) in
different tissues (leaves, inflorescences and rhizomes) of flowering and non-flowering shoots. This study also focused on the
biometry of these shoots.
