Abstract
In this of the presented paper results of the studies conducted in preceding four parts (I–IV) were synthetically assumed. On that background a comparative characteristics of specified stuble-field plant communities was conducted. It contains the most important features of communities and seats, in which they appear. In climatically, geomorphologically, hydrologically and with respect to soils differentiated conditions of South-East Poland, especially in former Rzeszów region, there were described stubble-field plant communities occurring as well on lowland, as on highland agricultural utility complexes. There were analysed 359 phytosociological records, in which 232 ones came from lowland, while 127 from highland complexes. The specified communities were included to two orders: Secali-Violetalia arvensis (suborder Polygono-Chenopodienalia : alliances Eu-Polygono-Chenopodion and Panico-Setarion) and Cyperetalia fusci (alliance Nanocyperion flavescentis). On the lowland agricultural utility complexes specified were seven types of communities: 3 belonged to Panico-Setarion alliance (association Digitarietum ischaemi; community with Setaria glauca and association Echinochloo-Setarietum), 2 to Eu-Polygono-Chenopodion alliance (the community with Euphorbia esula and Oxalis stricta as well the community with Veronica persica), while 2 associations from the Nanocyperion flavescentis (Hyperico-Spergularietum and Centunculo-Anthocerotetum) alliance. On the other hand, on the highland complexes of South-East Poland only 3 communities were found: 1) with Setaria glauca included to Panico-Setarion alliance, 2) with Veronica persica from Eu-Polygono-Chenopodion alliance and 3) Centunculo-Anthocerotetum association from Nanocyperion flavescentis alliance. The specified floral types, as well as lower units (variants and sub variants), reflected the mechanical structure, hydrological conditions and pH soils in their seats, what confrumed a great differentiation of soil conditions on the tested area.
