6. Triglochineto maritimi-Asteretum pannoniéi (Soó 1927) Topa 1939

Asociatia se instaleazä Tn imediata apropiere a fitocenozelor edificate de Salicornia, spre partea sud-vesticä a lacului Jabenita, sub forma unor pälcuri relativ extinse, exterioare trestii§urilor precum §i la Or§ova pe DI.SIatini. Fitocenoze cu Triglochin maritima au mai fost identificate §i Tn apropierea comunei lbäne§ti (tabel nr.7). Analizänd asociatia din punct de vedere ecologic observäm predominanta speciilor mezo-higrofile, micro-mezoterme §i slab acid-neutrofile (tabel nr.8). Din spectrul bioformelor constatam dominanta hemicriptofitelor (57,69%), urmate de terofite (23,07%) fig.4. Analiza corologicä evidentiazä predominanta eurasiaticelor §i a cosmopolitelor (19,23%) urmate de paleotemperate §i eurosiberiene (15,38%) fig.6. Speciile diploidie sunt Tn proportie de 50%, iar cele poliploide 38,46% (fig.5).
