The relation of lenght, leaf area, phytomass and content of energy in selected herb species to different permanent ecological conditions of the 5 natural spruce ecosystems in the Bielovodska dolina valley (Vysoke Tatry Mts) was studied. The canopy of spruce stands and light conditions of phytocoenoses were dependent on content of skeleton and/or depth of podzolic soils. The differences in permanent ecological conditions were the most remarkably reflected in changes of energy content and length of the studied herb species individuals. Significant changes in energy content were primarily found in Oxalis acetosella (in 90% of cases), Dryopteris dilatata (70%) and Luzula sylvatica (70%), in the case of length in Vaccinium myrtillus (80%) and Homogyne alpina (50%). Among the life forms of the plant species, hemicryptophytes were dominant (67-73%), less abundant were geophytes (12-22%) and chamephytes (10-18%).
