Résumé :
|
Northern Greece is regarded as the richest area in Greece in water ecosystems. The main object of this work is the study of the vegetation of hydrophytes (ephydates, hyphydates and free-floating macrophytes) from a phytosociological and ecological standpoind in the most important hydrobiotopes of Northern Greece. Firstly the taxa of aquatic macrophytes which constitute the flora of the area were determined and their distribution in the study area was noted. 48 taxa of hydrophytes and 40 taxa of hyperhydate macrophytes were recognised. Two of these Marsilea quadrifolia and Najas graccilima are mentioned for the first time. while three more rare species Azolla filiculoïdes, Riccia fluitans and Ricciocarpos natans were collected from new biotopes. The determining of the plant associations which constitute the aquatic macrophytic végétation of the area took place based on the floral analysis of its make-up, using the methods of the phytosociological school of Braun-Blanquet. Again based on the phytosociological tables which were obtained the life and growth forms spectrums and chorological spectrums of the plant associations are give as synthetis characteristics.
