Referat wygłoszony 15 lipca 1999 r. w Skierniewicach na XXIII Konferencji Naukowej z cyklu: Rejonizacja chwastów segetalnych w Polsce, zorganizowanej przez Pracownię Herbologii Instytutu Warzywnictwa w Skierniewicach. Tematem konferencji było przenikanie gatunków ruderalnych z siedlisk sadowniczo-parkowych do zbiorowisk segetalnych upraw rolniczo-warzywniczych.

On the basis of 15 phytosociological releves the ruderal variant of the association Echinochloo-Setarietum was distinguished in the field cultivations of vegetables. This distinction was due to the abundant presence of species characteristic of the class Rudero- Secalietea. The described ruderal variant of the association reflects the natural conditions and various human impacts in the investigated agrophytocenoses.

The first part of the present study contains short pieces of information on the Sieradz Province, its physico-geographic regionalization, geobotanic division, idaphic and climatic conditions. The second part discusses endangered and threatened species of various groups of segetal plants of the area. The final part describes several localities of floral refuges in the catchment of the middle Warta River.

Arable lands occupy about 30 percent of the area of the Załęcze Nature Park. Segetal weed associations in cereal plantations and in root crops were studied, and there were distinguished 6 associations, 3 communities, and several phytosociological units of lower rank. From geographical and ecological points of view, the presence of Arnoserido-Scleranthetum and Lamio-Veronicetum politae is of great significance here. Among species of weeds rare in this part of Poland are: Sherardia arvensis, Stachys annua, Bromus secalinus and others (for summary see page 565-566).

Misopates orontium is rarely observed in segetal communities of our country, including Central Poland. Its localities of small surface areas and low abundances are most frequently recorded. It is them that are most threatened with various factors, which frequently accumulate.

Observations on the segetal flora of the Belcliatow Mining-Energetic District (BMED) were carried out in the years 1976—1980. 248 species of vascular plants were found on segetal stands of this district, among them 65.3% of annual species. From among 248 species of vascular plants, 154 species belonged to apophytes (62.3%) and 94 species to anthropophytes (37.7%). Among apophytes most abundant are meadow species (27.9%), species of sandy turfs and sands (21.4%), aquatic (19.5%), forest and shrub species (14.3%) and species of xerothermic turfs (11.7%). The group of anthropophytes is dominated by archeophytes (67%). The composition of the segetal flora of BMED is consitioned by natural factors and by diverse factors connected with agriculture.

W pracy podano wykaz 248 gatunków chwastów, zanotowanych w latach 1976—1980 na siedliskach segetalnych Bełchatowskiego Okręgu Górniczno- Energetycznego (BOGE). Wśród roślin naczyniowych tego obszaru przeważają gatunki krótkotrwałe (65,3%) oraz apofity (62,3%).

The article contains presentation of results of the studies on the vascular flora in the external dumping ground of Lignite Mine "Bełchatów", which were carried out in the years 1979-1984. The flora includes 233 species with 46 species among them being planted or sown.

The article presents results of the geobotanical studies on the partial forest reserve of "Lasek Kurowski" situated near Wieluń in the Sieradz Administrative Province. An object of protection are the Tilio-Carpinetum with participation of the Abies alba and fragments of the Ribo nigri-Alnetum.

The floristic-phytosodological and ecological differentiation of agrophytocoenoses of the Bełchatów Mining Energetic District were presented. The expected directions of changes of field phytocoenoses, of this region wire pointed out and factors responsible for this process were determined. It was assumed that these processes are going to cause impoverishment of segetal plants and contribute to origination of simpler systems, less stable and less resistant to anthropopression.

Samples of 5 vascular plant species: Achillea millefolium L., Artemisia vulgaris L., Festuca gigantea (L.) VILL., Ranunculus acris L. s. str. and Vicia angustifolia L. were collected near Fuel Storage Station, Chemical Fibre Factory “Wistom” in Tomaszów Mazowiecki and Sewage Treatment Plant in Sulejów. Genotoxicity of environmental pollution was analysed using micronucleus assays in pollen mother and root tip cells in comparison with plant material collected in the Tatra and Babia G óra National Parks. Abnorm alities in morphology of plants growing in polluted areas were also found. The cytogenetical analyses revealed positive correlation between the percentage of micronuclei and the presence of heavy metals in soil. Pollen mother cells (germ line) were found more susceptible to DNA damage as compared with root tip cells (somatic line).
