Segetal Communities

This paper presents the results of research on changes in segetal communities of flax and root crop cultures of the Piotrków Plain (see W a r c h o l i ń s k a, 1994 - Figure 1) which took place during the period between 1971 and 1972 and between 1992 and 1993. On the basis of 72 phytosociological records, taken in 50 localities (Figures 1, 2) in the years of 1971 and 1972, 5 associations were distinguished: one in the flax culture (Table I) - Spergulo-Lolietum remoti and four in the root crop cultures (Tables II-V) - Digitarietum ischaemi, Echinochloo-Setarietum, Galinsogo-Setarietum and Lamio-Veronicetum politae. According to the repeated listing carried out in the years of 1992 and 1993 the changes in the communities of the above - mentioned items were stated. The comparison of the present state of these communities with their state of 22 years ago allowed to note that the changes of the analyzed agrophytocoenoses of flax and root crop cultures are caused by progressive anthropopressure.

This paper presents the results of research in segetal communities of winter cereal cultures of the Piotrków Plain (Figure 1) which took place during the period between 1971 and 1972 and between 1992 and 1993. On the basis of 205 phytosociological records, taken in 103 localities in the years of 1971 and 1972 (Figure 2), 6 associations were distinguished (Tables I-IX): Spergulo-Veronicetum dillenii, Arnoserido-Scleranthetum, Papaveretum argemones, Vicietum tetraspemae, Aphano-Matricarietum, Caucalido-Scandicetum. According to the repeated listing carried out in the years 1992 and 1993 the changes of the communities of the mentioned items were disclosed. The comparison of the present state of the weed communities of the winter cereal cultures on the researched area with the state of 22 years ago allowed to note that the changes in the analyzed agrophytocoenoses are caused by progressive anthropopressure.

Segetal Communities

In the years 1973-1978 floristic and phytosociological investigations were performed on field cultures on rendzina soils near Sieradz, by the middle part of the Warta river. The mosaic character of the soil of the investigated area on which segetal communities had developed and the continuous interference of a man (an anthropogenic factor) cause a large diversity in the examined area. Altogether in grain and root crop cultures there were distinguished 5 associations, 6 communities and many lower phytosociological units (subcommunities, facies and degree of moisture). Among the distinguished units of vegetation Caucalido-Scandicetum and communities with intermediate structure deserve particular attention. The association has an impoverished structure, only partly developed, which is probably due to the northern limit of the range of occurrence, habitat conditions (mainly edaphic) and the level of agriculture.

Segetal Communities

The article presents the results of studies on segetal communities in Bolimów Primeval Forest carried out in the years 1981-1985. The analysis of 205 phytosociological records has allowed to distinguish 7 associations and 2 communities (Tables I-XIV). Among the most common communities on this area are: Teesdaleo-Arnoseridetum minimae and Digitarietum ischaemi. On the other hand, very rare communities include: Spergulo-Veronicetum dillenii, Papaveretum argemones, a community from Saxifraga tridactylites and a community from Ranunculus arvensis. The distinguished communities reflect the present state of the ecological productive potential, they represent specific types of the habitats of potential natural vegetation, and show a distinct relationship with definite habitat units - soil-agricultural complexes.

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 Panico-Setarion alliance were distinguished. Most often, patches of the association Echinochloo-Setarietum 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: Echinochloo-Setarietum setarietosum glaucae in a typical variant and a variant with Juncus bufonius, both with subvariants with Digitaria ischaemum, as well as a typical variant of Echinochloo-Setarietum typicum, a variant with Juncus bufonius and a subvariant with Oxalis stricta in the typical and wet variant. Another association found in root crops on light soils of the Podlaski Przełom Bugu mesoregion is Digitarietum ischaemi. 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, Digitarietum ischaemi is differentiated into the typical and wet variant. Quite frequent patches of the Setaria pumila-Setaria viridis community were noted in intermediate habitat conditions, between those characteristic for Digitarietum ischaemi and Echinochloo-Setarietum.

This article presents the results of research on segetal vegetation of root crop cultivations of the area around Sieradz and Zduńska Wola, carried out in the years 1977 and 1992 (Figure 1). On the basis of 120 phytosociological records, taken in 1977, 6 associations were distinguished (Tables 1-8): Digitarietum ischaemi, Bilderdykio-Lamietum amplexicaule, Galinsogo-Setarietum, Echino-chloo-Setarietum, Veronico-Setarietum pumilae, Lamio-Veronicetum politae. According to the repeated listing, conducted in 1992, changes of the above - mentioned associations were stated. The comparison between the present state of the associations of root crop weeds on the area researched and their state of 16 years ago showed their impoverishment (compare Tables 1-9, Figures 2-9).
