Abstrakt

Our study was designed to describe possibilities to estimate above- and below ground biomass of selected grass species by means of seedling development. Festuca  arundinacea Schreb., Festuca  rubra L.,  Lolium perenne L., Poa pratensis L., Koeleria macrantha  (Ledeb.) Schultes, Deschampsia  caespitosa  (L.) P.B. were used in our experiment. On the basis of observations and measurements, differences between species, cultivars and ecotypes were described. Significant and positive correlation was found between root: shoot ratio at seedling phase and at mature plants.
