Zbiorowiska roślinne ściernisk na nizinnych kompleksach glebowo-rolniczych południowo-wschodniej Polski. Część II. Zbiorowiska ze związku Eu-Polygono-Chenopodion [The stubble-field plant communities on lowland complexes in South-Eastern Poland. P. II. Plant communities of the Eu-Polygono-Chenopodion alliance]

Abstract

Part I deals with the Panico-Setarion stubble plant communities. Part II describes the Eu-Polygono-Chenopodion plant communities. Part II is based on 89 photosociological records. The Eu-Polygono-Chenopodion plant communities develope on soil rich in nutrients (brown soil developed from silts loess and clay; alluvial soils developed from silts and loams; chernozem and black soils), belongs to wheat complexes. Two plant communities are distinguished: 1) Oxalis stricta-Euphorbia esula community; 2) Veronica persica community divided into four variants. The floristic diversity of these plant communities reflects the ecological conditions of the examined region.
