Studies on the variability of common wild oat (Avena fatua, Poaceae) in north-eastern Poland.

Abstract: This paper presents the frequency of occurrence of four varieties of Avena fatua L. in north-eastern Poland. In 1993 samples consisting of 100 A. fatua panicles were collected randomly from single fields (each of about 1 ha) of spring cereals, located in 20 different villages. In all 2000 panicles were collected representing 20 populations of the species, and the percentage of each variety was determined. Similar studies in the same 20 localities had been made previously, in 1981. The frequency of particular varieties had changed noticeably after 12 years. In 1981 var. fatua was the most frequent and represented 29.6% of the total. By 1993 this percentage had fallen to 12.2. An even greater change was noted for var. intermedia (Lestib.) Lej. & Court.  In 1981 its frequency amounted to 28.4% and in 1993 it was only 5.5%. At the same time there was an over two fold increase in var. glabrata Peterm. (from 22.4% to 48.8%) and one almost as great in var. vilis (Wallr.) Hausskn. (from 19.6% to 33.5%).

Taxonomy, cytogenetics and phylogenetic relationships in the Lolium-Festuca complex (Poaceae): I. Lolium - a review.

Abstract: Species belonging to the Lolium-Festuca complex constitute an important group of grasses of temperate climates. The closely related genera Lolium L. and Festuca L., widely distributed and very valuable for agriculture, have been the subject of numerous fundamental studies as well as plant breeding. Nevertheless, their systematics and evolution still need to be elucidated. This article reviews the present state of knowledge of the taxonomy, distribution, karyotype, hybridization, chromosome relationships and phylogeny of the Lolium-Festuca complex. The first part is devoted to the genus Lolium.

The genus Dactylis (Poaceae) in Poland in relation to its Eurasian distribution.

Abstract: The genus Dactylis L. is a polyploid complex which consists of 16 diploids (2n = 14), 7 tetraploids (2n = 28) and 2 hexaploids (2n = 42), distributed mostly in Central Europe and also in Asia and North Africa. In Poland it is represented by one species Dactylis glomerata L., within which three subspecies as well as their hybrids have been distinguished: subsp. glomerata (2n = 28), subsp. aschersoniana (Graebn.) Thell. (2n = 14) and subsp. slovenica (Dom.) Dom. (2n = 28).

Chorological-ecological model of the spread of Puccinellia distans (Poaceae) in Central Europe.

Abstract: This work attempts to describe a chorological-ecological model of the spread of Puccinellia distans (L.) Parl. in Central Europe. The reasons for the progress made, and the basic features of the mechanism of this process are presented. It has been emphasized that the success of this species in the colonization of new habitats and areas is connected with the presence of many features facilitating adaptation. These features occur at all stages of the population development: from seed dispersal to germination and completion of the life cycle.

Embryo morphology in the genus Bromus (Poaceae).

Abstract: Fifteen species of the genus Bromus L. are described using fourteen parameters of embryo morphology. Analyses of correlation suggest the partially separate development of the coleorhizal papilla, embryo axis and scutellum and point to a two-stage development of the coleoptile. The variation of characters is smaller in autogamic species (B. diandrus Roth) and larger in allogamic one (B. erectus Huds.). The length and shape of the embryo, the formation of embryonic lateral roots and the width of the coleorhizal papilla provide the best characters for separating species. The width of the scutellum, the length of the embryo axis and the dimensions of the papilla provide useful information about the embryo. Lateral roots were noted in sections Genea Dumort. and Bromus L. Taxonomic analysis revealed similarities between species of sections Ceratochloa P. Beauv. and Pnigma Dumort. Large polymorphism of accessions in B. sterilis L. and B. diandrus results from their autogamy. The intersectional status (sect. Bromus - Genea) of B. pectinatus Thunb. is confirmed, as well as the distinct peculiarity of B. hordeaceus L. within section Bromus. B. secalinus L., B. arvensis L. and B. commutatus Schrad. form a distinct complex. Classification of the genus Bromus using embryo morphology agrees well with the data on plant morphology, meiosis in interspecific hybrids, karyotypes and serology.

The vegetation of rice fields in North Korea and its relation to South Korea and Japan.

Abstract: This paper presents some phytosociological data on the weed vegetation of rice fields in North Korea (D.P.R.K.). Only the association Sagittario-Monochorietum vaginalis Miyawaki 1960, described and known from the territory of Japan and South Korea, was found in all localities in the studied area. The variability of this community and the geographically induced differences exhibited by it in North Korea are reflected in the newly described syntaxa classified at subassociation level: S.-M. najadetosum gramineae, S.-M. limnophiletosum sessiliflorae, and S.-M. sagittarietosum aginashi. Comparison with phytosociological relevés of this community from Japan and South Korea is included. One hundred and eleven relevés were analysed and the results clearly confirmed the phytogeographical differentiation of North Korean communities.

Diatom communities occurring in Niebieskie Źródła near Tomaszów Mazowiecki, Central Poland (1963-1990).

Abstract: In the plankton of Niebieskie Źródła (=Blue Springs) karst limnocren 152 diatom taxa were determined. The present study covers a period from 1963 to 1990 and discusses 12 samples of phytoplankton. A group of 38 constant (dominant) species, comprising taxa occurring in 80% to 100% of the samples (constancy according to the Braun-Blanquet V-degree scale), was distinguished. The dominant species (about 10% per 500 specimens) were: Amphora libyca, A. pediculus, Fragilaria construens, F. construens fo. venter, F. intermedia, F. pinnata, F. virescens. The following are taxa of special interest which characterize this reservoir: Navicula hasta, rarely noted in Poland and other countries (often in fossil state), N. laevissima, characteristic of oligosaprobic and alkaline waters, N. oblonga, found in alkaline waters and N. striolata, whose occurrence has not been exactly defined yet.

Tipo de dispersión, germinación y crecimiento de plántulas de Sagittaria latifolia (Alismataceae).

Abstract: Sagittaria latifolia Willd. (Alismataceae), a perennial helophyte that propagates through both sexual and asexual reproduction. We studied the morphological characteristics of achenes related to their dispersal type, some factors affecting their germination and growth of seedlings. This species produce many achenes, and probably its dispersal type is through hydrochory and epizoochory. The germination was better at 25oC; the germination increased with imbibition time and temperature. One hundred percent of germination occurred in achenes in imbibition for 12 days in darknes at 25oC. The growth of seedlings of S. latifolia was affected by the temperature during the early stages: each organ of the seedlings grows differently in dependence upon this factor for example, the roots grow and emergence was faster at 25oC; while the cotyledon and first leaf was at 30oC.

Aérophytologie comparée de deux milieux urbains de l'hémisphčre nord (Montréal et banlieue parisienne).

Abstract: Lists of plant particles in the atmosphere were compiled in July and August 1991 and 1992 in two towns in the Northern Hemisphere, Montreal (Québec, Canada) and Athis-Mons (a southern suburb of Paris, France). Both are situated in regions in which the climax vegetation is deciduous forest. Particles of all systematic groups occurred in the atmosphere. Important components were pollen grains of members of the Asteraceae whose different flowering times caused grains of Artemisia in Europe to appear earlier than those of Ambrosia in Canada. Spores of bryophytes and pteridophytes were scarce. Fungal spores were the most abundant and diverse particles in the atmosphere of both urban habitats. The numbers were higher in Paris (35000) than in Montreal (25000), although 58% more taxa were represented in Montreal (60) than in Paris (38). Climatic variations were responsible for differences of up to 15 days in the peak dispersal times of different systematic groups. The number and diversity of fungal spores were probably affected, not only by the vegetation, but also by its zonation and man's influence on the habitat..

Spatial differentiation of the field layer in relation to soil pH in selected forest communities.

Abstract: One of the main features characterizing a plant community is its internal variability. The main aim of the present work is to identify the internal differences which exist within the vegetation of a site and to attempt to use them diagnostically for classifying communities. Along 18 transects, representing a wide range of slightly humid forest habitats (from poor coniferous forest through mixed-coniferous and mixed-deciduous to very rich deciduous forest) and different levels of human pressure (from natural communities in Białowieża Forest through semi-natural ones in Kozienice Forest to strongly disturbed ones in the industrial region of Upper Silesia), quantitative field-layer vegetation and humus-layer pH data were collected by regular sampling. Whereas site heterogeneity was appraised by pH variability along transects, the ordination (DCA) of subplots (Sampling Units, SUs) was applied for β-diversity assessment in the communities studied. The humus layer pH was strongly correlated with the 1st DCA axis in natural or near-natural communities. SUs representing transects strongly influenced by man did not follow the general model of vegetation-site differentiation. Within the model three patterns were distinguished: (1) site heterogeneity prior to vegetation variability (deciduous and disturbed coniferous communities), (2) vegetation variability prior to site heterogeneity (mixed-coniferous habitats), (3) environmentally and vegetationally homogeneous coniferous communities. Four frequency pH distribution types referred to: (1) coniferous and mixed-coniferous stands, (2) mixed-deciduous stands, (3) disturbed coniferous stands, and (4) deciduous stands. The vegetation structure of communities (DCA SUs' scores) and habitat variability (pH on SUs) were used in communities' classification, which confirmed the diagnostic value of the internal vegetation-site differentiation of communities. Different strategies of intra-community diversification and their possible factors were hypothesized.

Habitat conditions of the phytocoenoses of Nupharetum pumili in Poland.

Abstract: The results of studies on phytocoenoses of Nupharetum pumili Oberdorfer 1957 from the Pomeranian and Mazurian Lake Districts in Poland, based on ecological data are presented. Since phytosociological studies have been published which contain some information about the relationships between Nupharetum pumili and the plant communities of the classes Littorelletea uniflorae Br.-Bl. et Tx. 1943 or Potamogetonetea Tx. et Prsg. 1942, a comparative analysis of the habitats of Nupharetum pumili and the main associations of these classes in Poland was conducted. It is demonstrated that the phytocoenoses of Nupharetum pumili are associated with specific habitats. Their optimum development is in waters and on substrates mostly rich in total Fe, PO4-P, various forms of N and organic matter content, i.e. in markedly eutrophic habitats. Irrespective of the degree of habitat fertility defined by the proportions of N, P and organic matter content, the occurrence of the association studied is determined by low concentrations of Ca, Mg and Na in waters and substrates.

The spread and habitats of Eragrostis pilosa (Poaceae) in the Vistula valley.

Abstract: The results of studies conducted in the years 1991-1993 indicated that Hairy Love-grass - Eragrostis pilosa (L.) P. Beauv. occurred frequently in the valley of the Middle and Lower Vistula (600 km long), while only two localities were reported from the valley of the Lower San. It was recorded as a pioneer species in bare sandy, silty-sandy and gravelly-sandy bars growing in plant communities from the classes: Bidentetea tripartiti, Isoëto-Nanojuncetea, and more rarely - Salicetea purpureae. Sometimes it occupied large areas and occurred in pure patches. E. pilosa has been found in the Vistula valley for over 30 years; at present it is quite naturalized there. In Warsaw it was recorded both on sandy river banks as well as in ruderal habitats, mainly in plant communities of the classes Plantaginetea majoris and Chenopodietea. Distribution maps of this species in the valleys of the Vistula and San Rivers as well as in Warsaw were plotted. Routes and means of its migration were considered.

Chromosome numbers in selected species of Hieracium (Compositae) in the Sudeten Mts. and the Western and Ukrainian Eastern Carpathians.

Abstract: Chromosome numbers are reported for 18 collections representing ten taxa of Hie­racium L. Chromosome numbers are reported for the first time for H. chlorocephalum Uechtr. (2n = 4x = 36), H. stygium Uechtr. (2n = 36), H. silesiacum Krause (2n = 36), H. corconticum Knaf fil. ex Čelak. (2n = 27), H. conicum Arvet-Touvet (2n = 18), and H. chrysostyloides (Zahn) Chrtek jun. (2n = 5x = 45). The pentaploid chromosome number appears to be only the second count for any taxon of Hieracium s. str. above the level of tetraploid. In H. prenanthoides Vill. 2n = 27 was ascertained in populations from the Krkonoše Mts. (West Sudeten Mts.) and Vysoké Tatry Mts. (Western Carpathians). The mountain population of H. schmidtii Tausch from the Krkonoše Mts. (West Sudeten Mts.) was found to be triploid (2n = 27). In H. transsilvanicum Heuff. the number 2n = 18 was confirmed, and in H. nigritum Uechtr. 2n = 36 was ascertained.

The relationships among vegetation, geology and spectral response: a quantitative approach on the European beech (Fagus sylvatica, Fagaceae).

Abstract: Botanical and remote sensing approaches have been applied jointly in the south-eastern Massif Central of France. Homogeneous test sites have been identified in the field and their spectral responses extracted from SPOT and Landsat satellite imageries. Field radiometry using a Cimel instrument has been applied to plant individuals as well as laboratory experiments to determine the spectral and anatomical characteristics of plants. The study of the European Beech growing on different siliceous substrates shows a close link between the foliar palisade parenchyma volume, type of lithology, and the spectral response in visible and NIR ranges of SPOT-XS, Landsat-TM, and Landsat-MSS. Moreover, the poor photosynthetic capability of leaves from trees growing on arkose revealed by low optical density can be explained by geochemical variations.

Pollen-pistil interactions in Paspalum distichum (Poaceae).

Abstract: The aim of this study was to obtain experimental information about pollen-pistil interactions after self- and cross-pollination in the Paspalum distichum L. polyploid complex. Twelve clones were used to analyse pollen tube growth in the pistils by fluorescence microscopy after both types of pollination. After self-pollination pollen grains germinated and developed pollen tubes but, depending on the clone considered, growth of the tubes was arrested at different levels in the pistils. Three of the twelve clones showed a low frequency (<4%) of pistils with pollen tubes in the micropilar area. When the clones of the same cytotype were cross-pollinated it was observed that more than 75% of the pistils showed pollen tubes in the micropilar area. These results indicate that members of this polyploid complex are self-incompatible. They show a “weak” self-incompatibility reaction since early arrest of the pollen tubes at the stigma surface did not occur, but retardation and ultimate arrest of the tubes took place after penetration of the stigma branches and entry into the transmitting tissues of the pistil. Cross-compatibility among plants of the same cytotype demonstrates that there are differences in the genetic factors which govern the self-incompatibility reaction in this species.

A brief historical survey of moss studies in the Russian Arctic.

Abstract: Three periods in the study of the mosses of the Russian Arctic can be identified. The first was associated with investigations during geographical expeditions when the first bryophyte collections were made. The beginning of the second period coincided with geobotanical exploration of the Arctic. The examination of specimens which had been collected by geobotanists provided additional information on arctic mosses. The third period is characterized by the participation of professional bryologists in field investigations. New data on the ecology, biology and distribution of arctic mosses were obtained through this studies, resulting in 115 additional species for the moss flora of the Russian Arctic being found. This flora is now known to contain 530 species. Analysis of the distribution of species in the arctic region shows that floristical richness depends mainly on the extent of the study of regional floras, from the geographical position of the region and from variable relief, and, accordingly, diversity of habitat.

Liverworts of the Bieszczady Zachodnie Range (Polish Eastern Carpathians) - a vanishing relict boreal flora.

Abstract: 109 species of hepatics were determined in the Bieszczady Zachodnie Range during the collection period from 1954 to 1995. 51 of these are montane species, which grow either exclusively in the mountains or show only limited occurrence in the North Polish lowlands. There exists a distinct floristic boundary between the eastern and western parts of the region studied. Five species grow exclusively east of the Wołosaty river valley whereas four others occur only west of it. Several species show a distinct preference for one of these regions. Most interesting is the altitudinal distribution of hepatic species in the Range we studied. Thirty-five species are confined to the subalpine zone: they grow either exclusively in stations lying above the tree line or they show an obvious centre of occurrence there. These are either high montane taxa that usually (i.e. in other mountain ranges in Poland) grow on sites in subalpine or even alpine zones, or montane species occurring in all zones. Among these “subalpine” plants in the Bieszczady Zachodnie Range exist several species which are either exclusively forest species (e.g. Anastrophyllum michauxii (F. Web.) Buch) or grow principally in the forest zone elsewhere. Some of these are members of spruce forest associations and we conclude that they are relict plants which occured there in the early postglacial period (Boreal/Atlantic), when, most probably, spruce forest formed a separate zone (possibly a very narrow one) between the deciduous forest and the subalpine meadows.
During the period of over forty years of (intermittent) exploration of the hepatic flora of the Bieszczady Zachodnie Range, we have witnessed some drastic changes in the composition of this flora. There have been losses in the epiphytic flora which was very rich in the fifties. Two species, viz. Porella arboris-vitae (With.) Grolle and Metzgeria fruticulosa (Dicks.) Evans have disappeared completely, and depauperate epiphytic communities are present now only in a few places. Also the rich epixylic flora has receded rapidly; there are seemingly no complete losses of particular taxa, but the area occupied by this flora has diminished dramatically. Fos example, the very rich epixylic flora of the forest covering the slopes above the Wołosaty river is now degenerate (a complete lack of Scapania apiculata Spruce, which was thriving there in the fifties) and limited to the immediate neighbourhood of water. We have observed also the disappearance of Frullania tamarisci (L.) Dum. from the Bieszczady Zachodnie Range: this epipetric species in the region studied was present in at least eight stations in the fifties. We collected it in one station in 1985. Nobody has seen the plant since. The causes of these losses are probably global: the epiphytic bryophyte flora is vanishing from the whole territory of Poland. There are also hepatic species which have invaded the study area: Ptilidium pulcherrimum (G. Web.) Vainio was known in the fifties from only two stations located on the western edge of the region (Łopiennik Mt.); at present (1995) it is known from several places, some in the very heart of the mountains.

Racomitrium curiosissimum (Musci, Grimmiaceae), an exquisite new species from New Zealand.

Abstract: Racomitrium curiosissimum Bedn.-Ochyra & Ochyra, sp. nov., is illustrated and described as a new species of the subgenus Ellipticodryptodon (Vilh.) Bedn.-Ochyra & Ochyra from three collections from the South Island of New Zealand. It is a very distinct and immediately distinguished species by the following combinations of characters: (1) deeply plicate leaves; (2) thin- to moderately thick-walled, yellowish-orange to yellowish-hyaline alar cells forming decurrencies; (3) wide and long basal marginal borders composed of 18-25 hyaline, rectangular to elongate-rectangular cells with straight walls arranged in 2-4 rows; (4) costa relatively narrow, bistratose above and 3-stratose at the extreme base; (5) stems with numerous, noticeably densely packed, tuft-like lateral branches, which are secondarily divided into 3-4 branches, giving the plants a very robust and coarse appearance; (6) hair-points very long, prickly and strongly spinose; (7) the uppermost part of the leaf lamina hyaline and hispid; (8) the innermost perichaetial leaf strongly modified, pellucid, hyaline to yellowish-hyaline, rounded at the apex and without a hair-point; (9) calyptra mitrate, deeply plicate below; (10) peristome teeth deeply cleft into two prongs, roughly papillose throughout. All taxonomically important characters of the new species are assessed and its relationships discussed. The new species clearly belongs within the subgenus Ellipticodryptodon (Vilh.) Bedn.-Ochyra & Ochyra and should be placed in the section Ptychopylla Bedn.-Ochyra along with R. ptychophyllum (Mitt. in Lindsay) Mitt. in Hook. f. Two new subsections, Horrida Bedn.-Ochyra & Ochyra, subsect. nov. and Diaphana Bedn.-Ochyra ­& ­Ochyra, subsect. nov., are established to accommodate R. curiosissimum and R. ptychophyllum, respectively.
