摘要：The near elimination of inland salt marshes in Central Europe occurred throughout the 19th and 20th centuries, and the currently remaining marshes exist in a degraded condition. This work examines the impact of groundwater level on the growth of plants from a seed bank obtained from a degraded salt marsh in proximity to still existing one through an ex-situ experiment. An experimental tank was set up with the sample seed bank experiencing differing levels of water level. There were 1233 specimens of 44 taxa grown from the seed bank, of which 5 species were abundant, and 10 species are considered as halophytes. Only iLotus tenuis/i from halophytes was more abundant, and only five species of halophytes were represented by more than three individuals. The water level has a significant impact on the number of species (based on linear regression analysis) as well as species distribution among different water level treatments (a non-metric multidimensional analysis (nMDS) followed by linear regression). The results show a negative relationship between the average water level and the number of species. The water level did not affect the species composition of halophytes, but differences in individual species abundances were found among the halophytes. The species iBupleurum tenuissimum/i, iCrypsis schoenoides/i, iMelilotus dentatus/i, and iPlantago maritima/i grew on the drier and non-inundated soils. iTripolium pannonicum/i, iSpergularia maritima/i, and iLotus tenuis/i grew on both wet and dry soils. iTrifolium fragiferum/i and iBolboschoenus maritimus/i were found in places with water stagnant at the soil level. iPulicaria dysenterica/i grew in inundated soil.
