This article is the first published information on the occurrence of the snow-beds of Nardo-Gnaphalietum supini in the Western Carpathians. So far, localities of Nardo-Gnaphalietum supini phytocoenoses have been known exclusively from the Alps, the Black Forest, and the Eastern Carpathians. During this study, carried out in the Polish Carpathians, phytocoenoses of Nardo-Gnaphalietum were recorded...
Ascocoryne turficola, one of the rarest fungi in Europe, has been recorded for the first time in Poland. Its distribution presented on the map, ecological notes and morphology of ascocarps are based on the authors' own material.
The two pondweed taxa, new for the Polish flora, were found in the Drawa River in the Drawieński National Park (north-western Poland). Patches of P. x sparganiifolius started about 400 m below the mouth of the left-bank tributary, the Korytnica River, and ended about 5.5 km further downstream. The population colonized mainly a sandy substrate with varied particle size, moderately deep water, and moderate...
During studies of phytoplankton in Sumin Lake (Łęczna-Włodawa Lakeland), conducted from May till September 2001 and 2002, 15 taxa of the genus Pediastrum (Hydrodictyaceae, Sphaeropleales) were found. Among them there were common species as Pediastrum boryanum, P. duplex, P. tetras and P. simplex, but also rare species as P. integrum or P. kawraiskyi. An especially interesting species was P. orientale,...
The morphological properties of Schizothyrioma ptarmicae (Helotiales, Ascomycota), a fungus known from a single locality in Poland and infrequently reported from Europe, are described and illustrated. Schizothyrioma ptarmicae is a parasite of leaves of Achillea ptarmica. It has been found in the Myrico-Saliceto auritae and Cirsio-Polygonetum plant associations of the Słowiński National Park. Additionally,...
From plantlets of Byblis liniflora Salisb. (Byblidaceae), propagated by in vitro culture, four phenylethanoid glycosides - acteoside, isoacteoside, desrhamnosylacteoside and desrhamnosylisoacteoside were isolated. The presence of acteoside substantially supports a placement of the family Byblidaceae in order Scrophulariales and subclass Asteridae. Moreover, the genera containing acteoside are listed;...
Morphological properties of sporocarps and spores of Endogone lactiflua (Zygomycota, Endogonales), a fungus for the first time found in Poland, are described and illustrated. Endogone lactiflua was wet sieved and decanted from a sample taken from the zone extending from the upper soil layer to rhizosphere of Pinus sylvestris growing in a forest dune in northern Poland. The recovered spores mainly...
The present study showed the ecological differentiation of phytocoenoses dominated either by Myriophyllum alterniflorum or by Littorella uniflora, which in Poland are classified within the Myriophylletum alterniflori or Myriophyllo-Littorelletum association. The properties which best differentiated the waters of the above types of phytocoenoses were calcium and factors associated with the carbonate...
In carbohydrate-starved root meristems of Vicia faba subsp. minor, the expression of two Principal Control Points located at the final stages of the G1 (PCP1) and G2 (PCP2) phases has been found to be correlated with a marked decrease of protein phosphorylation within cell nuclei, nucleoli and cytoplasm. Adopting the same experimental model in our present studies, monoclonal FITC conjugated antibodies...
The distribution of four species of the genus Vulpia [V. myuros (L.) C.C. Gmel., V. bromoides (L.) S.F. Gray, V. ciliata Dumort. and V. geniculata (L.) Link] reported in Poland has been studied. Currently, V. myuros and especially V. bromoides are very rare species, and their greatest concentration can be found only in the Lower Silesia region. The number of their localities decreased after 1950 and...
Tamarix duezenlii, belonging to Tamarix L. ser. Leptostachyae (Bunge) Baum, is described as a species new to science. It is related to T. hispida Willd. and T. arborea (Sieber ex Ehrenb.) Bunge. From the former species it differs by its dense inflorescences, white petals and paralophic disc; from the latter by a shrubby habit, elliptic petals and calyx abruptly narrowed at the base. The species occurs...
Deschampsia antarctica Desv. plants collected on King George Islands (Antarctica) at two localities that differ in topographic and nutrition conditions exhibited morphological variation that differentiated plants of both locations. The molecular variation characteristic to individuals of both sites was tested using AFLP approach in order to verify whether morphological variation characteristic to...
A micropropagation method, through axillary shoot proliferation, was elaborated for Inula royleana DC. (Asteraceae), a medicinal plant native of Himalaya. Primary explants (cotyledonary node explants) and secondary explants (node explants of in vitro regenerated shoots) of the plant, inoculated on MS medium supplemented with 0.1 μM NAA and 5.0 μM kinetin, regenerated 3.4 ± 1.2 and 5.1 ± 1.9 axillary...
