Floristic research on segetal communities was carried out in 2000 on arable fields in the Skierbieszów Landscape Park and its protected zone. Three communities of segetal weeds in cereal crops, and two communities of segetal weeds in root crops were separated in the arable fields of the Skierbieszów Landscape Park. The community <i>Vicietum tetraspermae typicum</i> commonly occurred in cereal crops on brown soils developed from loess soils. The community <i>Echinochloo-Setarietum</i>, which belongs to root crops, was noted in the same habitat. The greatest richness of species was found in <i>Consolido-Brometum</i> and <i>Lamio Veronicetum politae</i>, with the average of 25 species in one record. Both communities were abundant in rare segetal species which are considered to be endangered in our country: <i>Adonis aestivalis</i>, <i>Euphorbia exigua</i>, <i>Lathyrus tuberosus</i>, <i>Muscari comosum</i>, <i>Thlaspi perfoliatum</i>, <i>Veronica polita</i>, <i>Agrostemma githago</i>.

Segetal Communities

This present paper, focused on root crop communities of light soils, is a part of the wide range characteristics of segetal communities of the Podlaski Przełom Bugu (Podlasie Bug River Gorge) mesoregion. On the basis of 160 phytosociological relevés made according to the Braun-Blanquet method, phytocenoses representing the <i>Panico-Setarion</i> alliance were distinguished. Most often, patches of the association <i>Echinochloo-Setarietum</i> were recorded in the study area. Heterogeneous habitat conditions affect its floristic diversity. Two subassociations of the phytocenosis, divided according to the species composition into 9 lower syntaxa, were identified on light soils. The following subassociations were distinguished: <i>Echinochloo-Setarietum setarietosum glaucae</i> in a typical variant and a variant with <i>Juncus bufonius</i>, both with subvariants with <i>Digitaria ischaemum</i>, as well as a typical variant of <i>Echinochloo-Setarietum typicum</i>, a variant with <i>Juncus bufonius</i> and a subvariant with <i>Oxalis stricta</i> in the typical and wet variant. Another association found in root crops on light soils of the Podlaski Przełom Bugu mesoregion is <i>Digitarietum ischaemi</i>. Its patches were observed in cultivations on light, acidic, poor soils. The characteristic feature of this community is the occurrence of numerous acidophilous species. In habitat conditions typical for the Podlaski Przełom Bugu mesoregion, <i>Digitarietum ischaemi</i> is differentiated into the typical and wet variant. Quite frequent patches of the <i>Setaria pumila-Setaria viridis</i> community were noted in intermediate habitat conditions, between those characteristic for <i>Digitarietum ischaemi</i> and <i>Echinochloo-Setarietum</i>.

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 <i>Lamio-Veronicetum politae</i>, <i>Galinsogo-Setarietum</i> and <i>Oxalido-Chenopodietum polyspermi</i> from the <i>Polygono-Chenopodion polyspermi</i> alliance were noted. Small patches of <i>Lamio-Veronicetum</i> and <i>Oxalido-Chenopodietum</i> 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 <i>Oxalido-Chenopodietum</i> developed in the river valleys on fertile muds and black soils. Typical plots of <i>Galinsogo-Setarietum</i> distinguishable by the mass occurrence of <i>Galinsoga parviflora</i> were only observed in the vicinity of farm buildings. Intermediate communities between <i>Panico-Setarion</i> and <i>Polygono-Chenopodion</i> polyspermi as well as phytocoenoces of <i>Echinochloo-Setarietum typicum</i> - subvariant with <i>Veronica persica</i> and <i>Echinochloo-Setarietum fumarietosum</i> - were also quite frequently noted in root crops on compact soils.

The characteristics of communities developing in cereal crops of the Mazowiecki Landscape Park are presented in the paper. The traditional methods of cultivation, a mosaic of fields, meadows and forests as well as a specific microclimate affect the occurrence of species-rich, syntaxonomically differentiated agrophytocenoses. The occurrence of 4 associations and 2 communities in the area of the Park was noted. On the poorest soils, the association <i>Arnoserido-Scleranthetum</i> was the most widespread and internally differentiated, whereas in more fertile habitats the association <i>Vicietum tetraspermae</i> was the commonest. The above mentioned associations were noted more frequently in winter crops than in spring cereals. Plots of the association <i>Papaveretum argemones</i> and intermediate communities, between <i>Arnoserido- Scleranthetum</i> and <i>Papaveretum argemones</i>, were seldom observed in the studied area. Plots with domination of species diagnostic for the order <i>Polygono-Chenopodietalia</i> occurred rarely in spring cereals, mainly in the protection zone of the Landscape Park. Single, impoverished plots of <i>Aphano-Matricarietum</i> were recorded in the south-eastern part of the Park.

Phytosociological Relevés

The research on the localities of <i>Avena strigosa</i> and on its increased occurrence in agricultural crops of the Podlaski Przełom Bugu was carried out in 1994-1998. The documentation of this research consists of 600 phytosociological relevés and the floristic records. The paper presents the composition and structure of the field plant communities where <i>Avena strigosa</i> was found. It occurs frequently on various soil types of the Podlaski Przełom Bugu. However, on the area examined it was found just in small numbers, covering up to 5% of the area, while in the eastern part of the area an increase in its occurrence was observed. In the area of the Podlaski Przełom Bugu <i>Avena strigosa</i> occurred in spring cereals in the communities of <i>Arnoserido</i>-<i>Scleranthetum</i> and <i>Vicietum tetraspermae</i> as well as in the poor field communities, with the character species of <i>Aperion spicae</i>-<i>venti</i> and <i>Panico</i>-<i>Setarion</i>. Additionally, <i>Avena strigosa</i> was also found in the field communities of root crops belonging to <i>Panico</i>-<i>Setarion</i> alliance; however, it was present there just in small numbers.

Segetal Communities

In floristic and phytosociological investigations on the cultivated fields of the Szczercowska (Widawska) Depression, in the period 1967-1971, 7 associations and 3 communities as well as numerous taxonomic lower units such as subassociations, variants and facies were distinguished. Vascular plants were represented by 258 species occurring as weeds on arable fields. Among them were some interesting and rare members of the segetal flora: <i>Adonis flammeus, Adonis aestivalis, Anagallis coerulea, Linaria elatine, Vicia grandiflora, Illecebrum verticillatum, Anthoxanthum aristatum, Herniaria hirsuta</i> and others.

Many years of fieldwork have led the authors to hypothesise that there is a single relatively species-rich arable weed community present across the Scottish Borders that is best expressed in broad-leaved root crops and in set-aside on imperfectly-drained soils, while the species-poor communities typically found in cereal crops are a degraded form of this. 102 samples have been studied to test this hypothesis and to search for a community typical of slightly calcareous well-drained soils. The community typical of imperfectly-drained soils has been defined and is considered to be a species-rich variant of the NVC OV13 Stellaria media-Capsella bursa-pectoris open habitat community. Species typical of well-drained soils have been shown to be scarce and not to form a distinct community, though they may well have done so in the past.

Marsh hedge-nettle, Stachys palustris, is a perennial Eurasian member of the mint family, which has become naturalized and weedy in some parts of eastern North America. It is a hexaploid member of a holarctic species complex, which differs morphologically from the primarily tetraploid North American forms. The production of fleshy tuberous rhizomes is the most significant distinctive feature. In Canada, it has been a weed of potato and root crops in Nova Scotia, New Brunswick and Prince Edward Island, although other crops and areas, such as soybean in Ontario, are also affected. Usually considered a wetland plant, it readily spreads into drier arable fields from adjacent ditches and wetlands. Several herbicides available for use in Canada have been found to provide limited long-term suppression in agricultural systems, with the best results obtained using combined pre-emergent and post-emergent applications.

This paper is the third and final part of a study attempting to analyse associations and communities in cereal crops of the Łuków Plain. It contains a description of intermediate and impoverished communities established in cereal crops of the Łuków Plain. Patches with phytocenoses without the combination of species characteristic of cereal associations were frequently observed. Impoverished communities of the alliance <em>Aperion spicae-venti </em>established in winter cereal crops. In turn, in spring cereal crops phytocenoses including species characteristic of tuber and root crops were found; they represented either a community with species characteristic of <em>Panico-Setarion </em>or an intermediate community with species characteristic of <em>Aperion spicae-venti </em>and <em>Polygono-Chenopodion</em>. Such communities are established, among others, because of production intensification which changes habitat conditions. Some patches found in the study area were intermediate between the two most frequently observed associations <em>Arnoserido-Scleranthetum </em>and <em>Vicietum tetraspermae</em>.
