The stubble-field plant communities on lowland complexes in South-Eastern Poland. P. I. Plant communities of the Panico-Setarion alliance

Abstract

Floristic diversity is characteristic for stubble-field plant communities. Those communities consist of both the species remaining after harvesting of grain and of the species developing in rootplant communities. The first part of this paper describes the plant communities of poor sites in the investigated region. It is based on 90 phytosociological records taken in August and September of 1972-1975 and on soil investigations. The Panico-Setarion alliance was made up of: 1) the Digitarietum ischaemi association, 2) the Setaria glauca community and 3) the Ecbinochloo-Setarietum association, the Setaria glauca community was divided into smaller phytosociological units.
