Abstract

In seven meadow stands of natural hydroseres the average total underground biomass ranged from 1.6 to 3.7 kg. m−2. The highest percentages of live roots (46–60%) and live underground biomass (1.40–1.61 kg. m−2) were recorded in stands situated around the middle of the hydroseres and the lowest values (18%; 0.48 kg. m−2 and 23%; 0.86 kg. m−2) were both on the wettest and the driest sites. The total underground/aboveground biomass ratios varied between 3.2 and 12.2 while the live underground/aboveground biomass ratios lay between 0.7 and 3.4.
