Concluzii:

Pe grindul Saele, cu intinse suprafete de teren saräturat, dominate de vegetatia de tip halofil, asociatia Puccinelietum distantis ocupä soluble cu о concentrate mai micá ín säruri solubile ín straturile superficiale §i umiditate mai redusá, comparativ cu alte asociatii vegetale halofile (Saticornietum europeae, Aeluropetum iittoralis, Suaedetum maritimae, etc. Soluble caracteristice acestei asociatii sunt de tipul soloneturílor, cu fertilitate medie spre ridicatä ín straturile supeboare. ín aceste conditii, dezvoltá о cantitate ridicatä de masä vegetalä, care se regäseste ín continutul bdicat al solului ín humus, contribuind ín maré mäsurä la ameliorarea terenublor säräturate ale gbndului Saele. Valoarea furajerá a speciei Puccinellia distans, specia dominantá a asociatiei, este destul de bunä.

THE FLORISTICAL AND ECOLOGICAL CARACTERIZATION OF PUCCINELIETUM DISTANSIS S00 1937 ASSOCIATION ON SAELAE SAND BANKS

(Summary)

The Puccinelia distans fitocenosses have a large extended on the Saelae maritime sand bank, which is situated in the Razelm-Sinoe lagoonal complex zone. Puccinelia distans species influence in a great measure, the evolution of the local pedogenetic processing. The pedological processes are influence by the big biomass produced and the association specific microclimate. This association is growing on soil which contains high quantity of soluble salts, the strong alkaline pH of the soil and the moderate humidity. For a complete ecological caracterization of this vegetal association, we have made the periodic determinations of the local climatic factors, determinations of biomass, the soil humidity and physical and chemical soil property. The floristical aspects of this associations, in the searched zone, has been observed making up a great number of surveyings in different periods of the year.
