Sequences of epicuticular wax structures along stems in four selected tree species

Publicado en línea: 11 Mar 2015
Páginas: 9 - 14

Resumen

Abstract

Wax layer formation accompanies the processes of epidermis and cuticle formation. To examine these changes, observationsalong current-year long shoots of four woody species (Acer negundo, A. rufinerve, Gymnocladus dioica, and Gingko biloba) were made. Long shoots are suitable objects for such observations, because from the same stem, several samples can be obtained that represent a well-defined sequence of fragments of different ages.

The data that were obtained from different and sometimes distant stem regions suggest that epicuticular wax crystals appear on the stems very early and quickly, since they are found near the stem apex during intensive plant growth. This was confirmed for the four examined species. Some differences, however, were noted.

Very rapid production of prominent wax crystals was observed in stems. In an experiment involving mechanical wax removal from the A. negundo stem surface and subsequent analysis of the surface after several days via scanning electron microscopy (SEM), it was shown that wax regenerates very quickly. After only several hours, new emerging crystals were observed and their morphologies were essentially the same. Nearly full regeneration was observed several days after removal.

Seed morphology and anatomy of Hypericum elegans Steph. ex Willd.

Publicado en línea: 11 Mar 2015
Páginas: 15 - 18

Resumen

Abstract

Hypericum elegans is a rare perennial distributed primarily in Central and Eastern Europe. Seed morphology and anatomy in H. elegans was studied on the basis of a seed sample from its only locality in Poland. Scanning electron microscopy revealed that the seed coat of mature seeds is composed basically of 3 cell layers: epidermal, subepidermal and sclerenchymatic. They are documented graphically here.

First white-flowered species of Sertifera (Orchidaceae) discovered in Colombia

Publicado en línea: 11 Mar 2015
Páginas: 19 - 24

Resumen

Abstract

A new species of Sertifera is described and illustrated based on Colombian material. The novelty resembles Sertifera colombiana, but it is characterized by glandular leaf sheaths, larger, white flowers, ovate to oblong-ovate sepals, ligulatelanceolate petals and apically triangular lip. This is the first report of a white-flowered representative of the genus.

Survival problems of archaeophytes in the Polish flora

Publicado en línea: 11 Mar 2015
Páginas: 47 - 56

Resumen

Abstract

These considerations have been based on the updated list of archaeophytes appearing in Poland. The extent of endangerment has been assessed for particular species according to the updated IUCN classification. Non-threatened and invasive species have also been taken into consideration. A number of quite fundamental changes have been made to the classification, as compared to the publication of Zając et al. of 2009.

Alien plants in Poland: research directions and putting the results into practice

Publicado en línea: 11 Mar 2015
Páginas: 57 - 74

Resumen

Abstract

The aim of this study was: (i) to complete and verify the prior review of research on alien plants conducted in Poland and the practical use of their results, and (ii) to attempt to assess the contribution of the research from the area of Poland to the research conducted on an international level. The analysis was performed based on the information gathered during a literature search which covered the last 200 years, using over 1400 publications out of the 3000 which were available in the pool. As a result, the main areas of biological sciences in the context of the research undertaken on alien plants in Poland (distribution, ecology and biology of the species), the most common thematic studies (new species, new localities, and lists of alien species), and the most often investigated species, as well as tendencies over time were indicated. Although studies on the migration and distribution of alien plants in Poland have over 100 years of tradition, and the part of the studies conducted by Polish researchers contributes to the international scale research, it is still necessary to further analyse many issues and answer numerous questions.

Rare and threatened vascular plants of the railways in Slovakia

Publicado en línea: 11 Mar 2015
Páginas: 75 - 85

Resumen

Abstract

The paper presents data on the occurrence and secondary spreading of rare and threatened vascular plant species in railway habitats of Slovakia. We recorded 17 threatened vascular plant species and other 9 species that we considered to be rare in Slovakia. They grew at railway stations, mainly directly in the rail yard and also at the platforms or other similar facilities. Records of further 39 species were excerpted from literature sources. More native thermophilous species were represented among the recorded species as railway substrates provide suitable conditions for their growth. Also some archaeophytic segetal species were found quite frequent in the studied biotopes due to spreading of their seeds together with cereals transported by trains. Various habitats of railway transport facilities often provide suitable conditions for the secondary occurrence and further spreading not only of synanthropic or adventive, but also of rare and threatened plant species.

The association Geranio phaei-Urticetum dioicae Hadač et al. (1969) in Central Pomerania

Publicado en línea: 11 Mar 2015
Páginas: 87 - 92

Resumen

Abstract

Geranio phaei-Urticetum dioicae, a poorly known association of nitrophilous outskirts communities was characterized based on 16 phytosociological relevés. Its ecological requirements and distribution in Pomerania and Poland are presented. A new subassociations of the Geranio phaei-Urticetum dioicae allietosum ursini have been distinguished on the basis of differing species composition. Edaphic and phytocenotic conditions of the population were specified. Association is found in mineral soil of acid reaction abundant with nitrogen and phosphorus, and as to its quantity it belongs to less numerous ones at Pomerania.

Orchidaceae in the Pieniny Mountains (Western Carpathians)

Publicado en línea: 11 Mar 2015
Páginas: 93 - 100

Resumen

Abstract

Orchids constitute an important component of the Pieniny Mts. flora. The presence of 35 orchid species has been noted so far in this region. A considerable number of these species are endangered for various reasons. Eight species have been deemed extinct in the area. On the other hand, the orchid flora of the Pieniny Mts. includes species that widen their local ranges and can, thus, be considered expansive as well as new species, recently entered in the list of orchids occurring in the said mountain range (Epipactis microphylla and Epipactis muelleri). It is necessary and important to conduct an inventory of Pieniny orchid resources (the major aim of this study) that would be repeated at certain intervals, in order to know the number of stations and of individuals per population of each species, which would enable taking relevant actions needed to prevent the disappearance of these plants from the Pieniny Mts.
