Abstract

Analysis of plant communities accompanying root crops on compact soils is presented in the paper. It is the next part of the review of plant communities of agrocenoses of the Podlaski Przełom Bugu (Podlasie Bug Gorge) mesoregion. The studied phytocoenoses were identified on the basis of 103 phytosociological relev&#233;s, made according to the Braun-Blanquet method. In the studied agrocenoses, plots of the associations Lamio-Veronicetum politae, Galinsogo-Setarietum and Oxalido-Chenopodietum polyspermi from the Polygono-Chenopodion polyspermi alliance were noted. Small patches of Lamio-Veronicetum and Oxalido-Chenopodietum were rarely noted in the studied area due to a small proportion of suitable habitats. In the area of Podlaski Przełom Bugu mesoregion, phytocoenoses of Oxalido-Chenopodietum developed in the river valleys on fertile muds and black soils. Typical plots of Galinsogo-Setarietum distinguishable by the mass occurrence of Galinsoga parviflora were only observed in the vicinity of farm buildings. Intermediate communities between Panico-Setarion and Polygono-Chenopodion polyspermi as well as phytocoenoces of Echinochloo-Setarietum typicum - subvariant with Veronica persica and Echinochloo-Setarietum fumarietosum - were also quite frequently noted in root crops on compact soils.

Highlights

The present paper is the part of the review of plant communities of agrocenoses of the Podlaski Przełom Bugu mesoregion (Skrzyczyńska and Rzymowska, 2005; Rzymowska and Skrzyczyńska, 2006a; 2006b; 2006c; 2007)
Przełom Bugu mesoregion, there were observed plots of communities classified as Polygono-Chenopodion polyspermi
This calciphilous alliance is represented by: Lamio-Veronicetum politae, Oxalido-Chenopodietum polyspermi and Galinsogo-Setarietum. Little plots of these phytocoenoses were rarely observed in the investigated area

Summary

INTRODUCTION

The present paper is the part of the review of plant communities of agrocenoses of the Podlaski Przełom Bugu mesoregion (Skrzyczyńska and Rzymowska , 2005; Rzymowska and Skrzyczyńska , 2006a; 2006b; 2006c; 2007). It concerns the analysis of communities developing in root crops on compact soils. The characteristics of the agrocenoses were made on the basis of phytosociological relevés. The methodical principles, e.g., the list of localities with their numbering and the characteristics of the study area, were published in a paper by Skrzyczyńska and Rzymowska (2005)
