"Ecophysiological behaviour of halophytes communities in relation with natural habitat characteristics from Razelm lake vicinity (Danube Delta biosphere reserve)". Lucrări Ştiinţifice USAMV - Iaşi Seria Agronomie 61(1): 139-144.https://repository.iuls.ro/handle/20.500.12811/603The investigations were carried at the low, flat and flooded area near Razelm, Enisala, Beibugeac (Plopu) and Saraturii lakes (Murighiol) in Danube Delta Biosphere Reserve in different areas: 1310 - communities of Salicornia and other annuals colonising mud and sand; 1530* Pannonic salt steppes and salt marshes. The ecophysiological analyses were performed in representative plants belonging to the three identified plant associations (communities): Salicornietum prostratae Soó 1964, Astero tripoli – Juncetum gerardii Šmarda 1953 and Obionetum verruciferae Ţopa 1939. Investigated soils, Gleyc Solonceak and Sali-sodic Gleysoils, have medium or coarse-medium texture and electrical conductivity values varied from 1019 µS/cm up to 5427 µS/cm. The chlorophylls biosynthesis showed a higher amount of chlorophyll a in species of Poaceae and Juncaceae than in the Chenopodiaceae family. In Aeluropus littoralis species of the C4 - photosynthetic type, photo-assimilatory pigments varied slightly during the vegetation period. Among the carbohydrate fractions, the disaccharides, important in maintaining cell osmotic pressure, are increased and as well as polysaccharides.enhalophytesphotosynthetic pigmentscarbohydratesRBDDArticle2069-6727
