The stubble-field plant communities in South-Eastern Poland. P. III. Plant communities of mountain agricultural utility complexes

摘要

In the Part I and II the stubble-field plant communities of lowlands agricultural utility complexes in South-Eastern Poland were introduced. The Part III contains a description of such communities occurring in mountain complexes. In the years 1972-1975, since August till September, 95 phytosociological records were taken on the area elevated from 300 to 650 m over the sea level, embracing the Carpathian Foreland and the Low Carpathian region. The research was conducted upon the typical, acid and leached brown soils, as well as on clay, dusty clay and silt alluvial soils belonging to three mountain complexes: wheat, cereal and oat-potatoes. The following communities were specified: I. Setaria glauca community, divided into two variants: 1) typical; 2) with Aphanes arvensis ; II. Veronica persica community, divided into four variants: 1) with Aphanes arvensis , 2) typical, 3) with Geranium dissectum , 4) with Aethusa cynapium . The variant with Geranium dissectum , belonging to the community with Veronica persica , was considered as having the most mountain character.
