Considered to be the most natural of all other Polish stands Picea abies in Białowieza Forest has suffered severely of bark beetle damages for decades. In order to find out some historical events in native Norway spruce stands diversity at regional level, we carried out the study on polymorphism with DNA markers and performed Principal Coordinate Analysis (PCoA) on the basis of genetic distance matrix. Two ranges (i.e. Baltico-Nordic and Hercyno-Carpathian) of Norway spruce cover north-eastern and southern Poland, respectively. The spruceless zone separates the these two ranges in lowland Poland. From genetic point of view, the Baltico-Nordic P. abies populations mainly harbor mitochondrial haplotype 'c', whereas the spruces from the Hercyno-Carpathian range - haplotype 'a'. Until recently, the Białowieza Forest has been considered to belong to the northern range of spruce occurrence in Europe. Seven populations from Białowieza Forest were studied (two of them from the Strict Reserve in Białowieski National Park) according to mitochondrial DNA diversity, and compared with genetic diversity found in 24 other populations located in Białystok Regional Directorate of the State Forests (north-eastern Poland). All studied spruce populations were more than 100 years old and were of natural origin. As result, the spruces from the Białowieza Forest harbored three mitochondria] haplotypes of the nad1 gene ('c', 'a' and 'al'), with the haplotype 'a' being more frequently present (>51%) than the haplotype 'c'. The spruce stands from Białowieza Forest have the highest gene diversity (h Nei=0.527) comparing to the other stands from the Białystok RDSF. The PCoA proved the particularity of the spruces from Białowieza Forest grouping them into one cluster of genetic similarity. Our data demonstrated that most of Norway spruces populations from Białystok RDSF harbor haplotype 'c', which confirms their historical relationship with the Baltico-Nordic range of P. abies in Europe, while most spruces from Białowieza Forest have different historic origin, because they share high frequency of the southern haplotype 'a'. It also turned out that Norway spruce populations from two different European ranges met in lowland Poland after the last glacial period,as proved by the presence of two mitochondrial haplotypes 'a' and 'c'. It can be assumed, that the spruceless zone was created by human activity in the past millennia. The results of all molecular analyses confirmed the unique character of spruces of Białowieza Forest, which is distinguished by the greater richness of the gene pool in comparison to the region of Białystok RDSF as well as good adaptation to local environmental conditions.

In this paper we discuss the data on presence of truffles (Tuber spp.) in Polish literature and culture through the ages. The aim of this article was to give the historical data on truffles as well as the new ones together with the ongoing research on that ultimate fungi. Study concerning widely understood history of and research on truffles in Poland was based on review of literature dating back to XVII century. A total of 67 books and articles were reviewed. Given the rich body of literature, especially in the past centuries, we have come to the conclusion that truffles were well known to the Poles (at least to the nobles and the rich). Some factors determining truffle forgetfulness after the Second World War are given in respect to social, cultural and forests' management changes. The following reasons can be highlighted: (1) changes in the forest cover, which in 1945 was only 20.8% and furthermore unfavorable changes in the forest structure, the tree species composition and the management (undergrowth shading the forest floor) for truffle development; (2) changes in the structure of forest ownership and management, especially disappearance of traditional ways of forest use, such as cattle grazing and brushwood collecting; (3) changes of Polish State borders resulting in significant area of soils, which are conducive to truffles growing (chernozem) coming into the borders of Ukrainian territory; (4) social changes resulted from the extermination and deportations of Polish aristocracy and intelligentsia (including foresters) - knowledgeable social group of people regarding truffle collection, use and cultivation as well as migration of people from rural to urban areas and emigration from Poland, and (5) the fact that in time of communists regime there was no room to promote the gourmet products, especially if it was associated with the aristocracy. In consequence, truffles went into oblivion. Furthermore, the aspects of promotion and establishment of truffle orchards in Poland in the last decade are also presented. Based on the authors findings is clearly shown that there is a great potential towards promotion and growing truffles in Poland, especially Tuber aestivum Vittad. known as summer or Burgundy truffle. This species has a wide range in Europe and plasticity to different climatic conditions.

The study showed the genetic structure of nine Schrenk spruce stands, which represented altitude and geographical variants in the Tien-Shan mountains in Kyrgyzstan. Comparison between genetic structure of stands was based on frequencies of nuclear microsatellite (SSR) alleles occurring in three DNA loci. The total genetic differentiation of Schrenk spruce populations was low (FST=0.0651). Eight main groups of populations were distinguished in the dendrogram defined by Nei's genetic distances based on micro-satellite markers. © 2014, Polish Forest Society. All rights reserved.

In the situation of limited number of pesticides being approved for use in forest nurseries it is necessary to examine new products available on European market that stimulate growth and improve resilience and vitality of seedlings as a part of intgrated plant protection program. Paper presents test of fertilizer Actifos used in seven Polish nurseries in order to stimulate the growth of seedlings. In 64% of cases, Actifos stimulated increament of shoots (significantly for oaks, beeches, pines, spruces and alders) as well as for roots (significantly only for alders and oaks).

The use of biomass for energy purposes is an important European Union policy. In light of the restrictions concerning the use of the full-value wood from forests for energy purposes, short rotation forestry can become an alternative source of woody biomass. In this context, the most promising species is poplar (Populus spp.), productivity of which depends on various aspects such as plant spacing, cutting cycles, fertilization and cultivar characteristics. The aim of this study was to assess the possibility of cultivation of ten selected poplar clones from the section Aigeiros and Tacamahaca in short-rotation coppice in the climatic conditions of Poland. An experiment was set up in the north-eastern part of Poland in the Wichrowo Forest District. Survival, tree stocking, and biomass yield were compared. Productivity of clones was examined in five-year cutting cycle. The highest dry biomass yield (7.8 t/ha/yr) was achieved by the clone 'Hybrida 275'. In contrary, the biomass yield of the worst clone ('AF-8') amounted to 2 t/ha/yr. Some other Italian clones, such as 'AF-6' and 'MON' were not able to adapt to the local conditions at all and were excluded from the experiment. Because of the need to implement the full economic analysis of short rotation poplar plantations, it would be important to study propagation ability of certain currently studied varieties of poplar in subsequent rotations and with different production cycle period length up to the end of biomass production on a given plantation. Resistance to diseases of energy poplar plantations should also be researched.


The paper concerns the occurrence of small-leaved lime in the Polish forests on the basis of stand description contained in the main database of the State Forests. The analysis includes the geographical occurrence of lime in all forest layers and according to age class of stands with lime as well as their habitat and soil preferences. Special attention was paid to the stands with lime as the dominant species. © 2014, Polish Forest Society. All rights reserved.

The purpose of our study was to estimate genetic diversity of Prunus avium in natural populations. Genetic studies were carried out in 27 wild cherry populations sampled from several Polish tree stands. Chloroplast DNA variation was assessed and two haplotypes were identified. Theirs distribution divided populations into two groups. Haplotype H1 was present in 11 of 27 populations and H2 in 16 populations. The PCR-SSR technique was used to detect nuclear DNA diversity. Three highly polymorphic SSR (microsatellite) primer pairs were used to describe the genetic variation. Heterozygosity values ranged from 0.500 to 0.633, while gene diversity (PIC) from 0.75 to 0.79. This study demonstrated that SSR fingerprinting with cpDNA diversity, can be used for preliminary characterization of Prunus avium populations.
