Opis:
The available phytosociological data and original observations were used for preparing a list of plant communities with Sorbus torminalis on its natural sites in Poland. The community context of its sites showed a wide range: from pine-oak forests (alliance Dicrano-Pinion) and oak forests (Quercetalia robori-petraeae, Quercetalia pubescenti-petraeae) to oak-hornbeam forests (Carpinion) and beech forests (Fagion). Oak-hornbeam forests (Carpinion) are the most frequent communities with S. torminalis in Poland. Despite this, oak forests (especially the open thermophilous forests of Quercetalia pubescenti-petraeae) seem to be the most suitable sites for growth and reproduction of this light-demanding tree species. Some remarks on S. torminalis conservation in the community context were also presented as its passive protection in some forest reserves has proved to be ineffective or even harmful.

Opis:
The paper presents the proposal of a strategy of conservation of genetic resources of wild service tree (Sorbus torminalis) in Polish forests. Some results of the recent studies on distribution, resources and genetic variability of wild service tree in Poland that make a scientific base of the programme are presented. Both in situ and ex situ methods should be applied in conservation of genetic resources of S. torminalis. Conservation affords should first to be focused on forest management oriented in favor of wild service tree (e.g. logging intervention, competition control, preparing of favorable sites for new establishments). Further, in situ measures should include selection of conservation areas (natural gene reserves) and preserving trees of the best quality (protected genotypes). These objects would provide seeds for new establishments and to feed populations of small size. The genotypes of the selected earlier preserving trees (about 250–300) would be protected in ex situ conservation objects – seedling and clonal seed orchards. These plantations would also provide seeds needed for future establishments. The genotypes of endangered populations or single trees of S. torminalis could be preserved in the Forest Gene Bank in Kostrzyca.

Opis:
The results of the study on morphological variation of fruits and seeds of a rare forest tree species Sorbus torminalis (L.) Crantz in Poland are presented and discussed. The ripe fruits were collected from 13 localities widespread within the range of the species. Fruits and seeds were measured according to 13 morphological traits. The biometric data were subjected to multivariate statistical analysis in attempt to define intra and inter populational variation. Most of the fruit and seed traits are significantly correlated and are characterized by moderate level of variation. Traits describing size and shape are higher variable in seeds than in fruits. High level of variation within examined populations was ascertained. The average among population component of variation was only 23.99%. Though the differences between sampled populations are significant, almost no geographical pattern of this differentiation was detected. The biological significance of some of fruit and seed features is discussed in the paper. Examining the collected material a single fruits with 5–6 seeds were found what suggests the presence of three carpels in gynoeceum, a number not previously reported in the species.

Opis:
This paper presents the results of the study on morphological variability of leaves of a scattered tree species Sorbus torminalis (L.) Crantz) in Poland. The leaves from short- and long shoots were collected from 17 localities widespread within the range of the species in Poland. Leaves were measured according to 15 morphological traits. The biometric data were subjected to multivariate statistical analysis in attempt to define variability between local populations. Most of the leaf traits are significantly correlated and are characterised by moderate level of variation. The average among population component of variation was 32.82% and 27.46% for leaves on short- and long shoots, respectively. The differences between sampled populations are significant, but only a weak geographical pattern of this differentiation was detected. Clinal type of variation was ascertained in two traits. Leaf traits which discriminate best the studied populations are also indicated. It was proved that leaves on short shoots differ markedly in shape and size from those of long shoots. Leaves on long shoots are steadier, but morphological trait values are less correlated. The study also confirmed the occurrence of individuals with leaves characteristic for S. torminalis var. perincisa Borbas et Feck and S. torminalis f. mollis Beck in a few Polish populations.

Opis:
The aim of this study was to give ecological characteristic of D. mezereum. Ten populations from the Wielkopolska Lowland were examined. The habitats (plant communities, coenotic relations and soil conditions) of D. mezereum populations were described. 14 individual characters of D. mezereum shrubs (1 – leaf length, 2 – leaf width, 3 – leaf shape, 4 – possition of the widest part in percentage of the leaf length, 5 – no. of leaves on annual shoots, 6 – annual shoots length, 7 – ratio of no. of leaves to shoots length, 8 – flower diameter, 9 – flower tube length, 10 – no. of flowers on shoots, 11 – ratio of no. of flowers to shoots length, 12 – fruit length, 13 – fruit width, 14 – fruit shape) as well as content of macro- and microelements in leaves were examined. The relations between individual characters of D. mezereum and soils and leaves chemical characteristics were studied. On the ground of investigations the following conclusions have been made: 1. In the experimental plots (1 m2) 104 plant species representing different syntaxa coexist with D. mezereum and the number of taxa in the plots range from 16 to 28. That gives information about broad sociological and ecological amplitude of D. mezereum. 2. The soils vary in physical and chemical characteristics but all of them have low content of phosphorus. 3. The optimum habitat conditions are characterized by good structure, friable and humus soils of pH 5.7-6.8 and average content of available nutrients within marshy meadow (Circaeo-Alnetum) forest communities. 4. High amount of Ca and Mg in D. mezereum leaves is highly correlated with most characters of leaves, shoots and fruits. High amount of Ca (independently from pH of soil) indicates its special role in mineral feeding of D. mezereum shrubs.
