摘要: The seed-bank in a Baltic sea-shore meadow was studied and soil samples were taken regularly along 60-m transect. transect reflected successional gradient. seed bank had its highest density around the mean water level for August, which about 10 cm above yearly level. It totally dominated by seeds of Juncus gerardii. depth distribution investigated. Only at two ten sampling points (i.e. August) could significant peak second from top be observed, otherwise quite even. A comparison between present vegetation revealed strong difference.
