Opis:
W pracy wykonano analizę plonu rodów owsa oplewionego i nieoplewionego. Dane pochodziły z doświadczeń wstępnych przeprowadzonych w 2008 r. Badano 27 rodów owsa oplewionego i 2 wzorce w 6 miejscowościach oraz 12 rodów owsa nieoplewionego i 2 wzorce w 5 miejscowościach. Do analizy plonu wykorzystano metodę graficzną biplot typu GGE (na efekty GGE składają się efekty główne genotypów G oraz efekty interakcji genotypowo środowiskowej GEI). Na podstawie wykresów biplot typu GGE scharakteryzowano genotypy oraz wskazano te o największym efekcie GGE w każdym środowisku. Spośród rodów owsa nieoplewionego we wszystkich badanych miejscowościach najwyżej plonowały i były dobrze adaptowalne: STH6264, CHD1368, a w przypadku owsa oplewionego: CHD1534, STH149, STH6038, STH12, KREZUS, POB3107. Zbadano stabilność genotypów typu dynamicznego tzn. wskazano genotypy, które nie wykazywały interakcji genotypowo środowiskowej GEI. Najbardziej stabilnymi rodami owsa nieoplewionego były: STH6294, CHD1408, CHD1438, CHD2567, CHD1368, a najmniej stabilnymi: STH108 i STH6315. Wśród rodów owsa oplewionego najbardziej stabilnymi były: CHD1156, CHD3833, STH12, CHD1193, zaś najmniej STH132 i POB3672. Określono genotyp idealny. Wśród rodów owsa nieoplewionego idealnym genotypem był STH6264, a w przypadku rodów owsa oplewionego STH12.
Under this study, a yield analysis of covered grain and naked grain oat strains was carried out. The data originated from the preliminary trial experiments accomplished in 2008. There were examined: 27 covered grain oat genotypes and 2 standards in 6 environments, and 12 naked grain oat genotypes and 2 standards in 5 environments. A graphical bi-plot method of GGE type was applied to the yield analysis (the GGE effects comprise a sum of main effects of G genotypes and the effects of GEI genotypic environmental interaction). Based on the GGE bi-plots, the genotypes were characterized and those showing the highest GGE effect in each environment were pointed out. From among the naked grain oat strains in all the environments studied, STH6264 and CHD1368 had the highest yield and were well adaptable, and as for the covered grain oat strains: CHD1534, STH149, STH6038, STH12, KREZUS, POB3107. A dynamic concept of stability was studied, i.e. those oat genotypes were identified, which did not show any genotypic environment interaction. The most stable naked grain oat strains were: STH6294, CHD1408, CHD1438, CHD2567, CHD1368 and the most unstable: STH108 and STH6315. The most stable covered grain oat strains were: CHD1156, CHD3833, STH12, CHD1193 and the most unstable STH132 and POB3672. An ideal genotype was determined. Among the naked grain oat strains, STH6264 was the most ideal genotype, whereas among the covered grain genotypes: STH12.

Opis:
The composition and structure of the breeding bird community in the Borki Forest in north-eastern Poland were investigated during two separate periods: 1994–1996 and 2012–2014. Bird censuses were carried out in three plots located in mature oak-hornbeam, ash-alder and mixed coniferous forest stands. A standard combined mapping technique for estimating the number of breeding birds was applied. A total of 74 bird species bred at least once within any plot during 1994–1996 or 2012–2014. The structure of the bird assemblages on particular plots displayed a high degree of similarity, exceeding 75%, which means that they represent essentially the same bird community. However, the investigated assemblages have changed substantially over the 20 years. Both, the number of breeding bird species and the population densities on all plots, were much higher in 2012–2014 than in 1994–1996. The mean number of breeding species on all plots was over 50% higher in 2012–2014 than in 1994–1996, whereas the mean total density of breeding pairs increased by more than 60%. Total population densities on the plots increased as a result of an increase in population densities of individual bird species combined with an increase in the number of breeding species. Due to different rates of population growth for certain species, also the composition of dominating species group have changed. The observed changes in the avifauna of the Borki Forest were most probably due to an enrichment of the forest habitats structure, which was caused by natural factors, such as ageing of forest stands, forest succession and a change in water regime by beaver dams, as well as by forest management, including group felling within or in the vicinity of plots and uncovering of the forest edge.

Opis:
The aim of the study was to determine the impact of increased timber logging after natural disasters on timber assortments, unit prices, as well as average prices of timber spruce and total timber. The net sales prices of the years 2004-2010, available from the database of the State Forests Information System (SFIS) for the Forest District of Węgierska Górka, were analysed and compared to the prices of selected forest districts within the Regional Directorate of State Forests in Cracow (RDSF). The forest districts were classified based on the volume of logged timber leading to a separation into two groups of two and six forest districts. Moreover, we tested for significance in the linear trends of relevant characteristics and determined confidence intervals. Furthermore, we calculated the rate of growth (decrease) of the unit prices. Our studies show a decrease in price of only some of the timber assortments despite a significantly increased supply. Price declines were observed for the average prices of timber spruce and total timber due to their lowered quality. The price of timber assortments was mainly determined by effects of macroeconomic factors.

This paper reports the construction a map based on Amplified Fragment Length Polymorphic DNA (AFLP) in Scots pine (Pinus sylvestris L.). The main purpose of map construction was its application to quantitative traits loci (QTL) mapping for breeding traits economically important in Scots pine breeding program such as tree height and diameter at breast height, number of needles and their length, width, and area. Genomic DNA of needles and haploid megagamethophytes from seeds originating from a single tree were amplified with 25 AFLP primer-enzyme combinations with three or four selective nucleotides. Sixteen of them generated easily readable patterns and revealed a polymorphism. Each analyzed marker was tested for the expected 1 : 1 segregation ratio using χ2 – test and only 6 were significant with (α ≤ 0.05). The total map size equaled 291,7 cM and all markers were distributed within one linkage group. For all traits only one QTL associated with tree height (H) was detected.

Opis:
Within the framework of work on the anatomical structure and durability features of wood, as well as analyses of radial growth, a preliminary analysis was carried out in regard to variation in the heartwood within Black locust trees. The research was carried out in three stands of straight-stemmed trees in western Poland. The variation displayed by the heartwood around its circumference and the eccentricity of the trunks was characterised with reference to: the heartwood radial index (HRI), the cross-sectional shape factor for heartwood (CSsf) and the pith eccentricity index (PEcc). The results confirmed a relationship between the degree of variation around the circumference of the heartwood and the mean age of the stands, while at the same time making clear the high level of differentiation in radial variation at the level of the individual tree. The findings suggest that the fertility of the habitat does not exert much of an influence on the generation of heartwood in Black locust trees. No statistically significant relationship was obtained when the circumferential variation of the heartwood was set against the total height or diameter at breast-height. Only in the case of crown length, and then only at the Wołów site, was there a moderate negative correlation with the coefficients of circumferential variation.

Opis:
Pedunculate oak (Quercus robur L.) is an important component of temperate forests in the north- ern hemisphere. It occurs naturally across Europe and in parts of North Africa, the Balkans, the Urals and the Caucasus. In Poland, it predominantly grows on the plains at ≤700 m a.s.l. The main objective of this study was to determine how different temperature-humidity growth conditions influence dormancy breakage and epicotyl emergence in Q. robur, using growth curve models. We also in- vestigated whether these differences result from changes in the climatic conditions under which the oak populations grow naturally. In this study, we selected four pedunculate oak stands in western and eastern Poland. These sites were char- acterised by oceanic and continental climates, respectively. Mature acorns were collected in the autumn of 2016 and pretreated for two weeks in the cold (4 °C). The acorns were then sown in plastic pots filled with a peat/sand substrate. Four climatic variants (cold-dry, cold-wet, warm-dry and warm-wet) and a control (average conditions) were used. Epicotyl emergence was monitored daily for 74 days. Epicotyl emergence dynamics (maximum absolute growth rate, lag time, T50), number of days to epicotyl emergence, and cu- mulative epicotyl emergence were measured or calculated. The acorns from oceanic climates required more intense warm humid conditions for epicotyl emergence than those from continental climates. In contrast, acorns from continental climates had an evolutionary advantage in that their epicotyl emergence occurred both in cold-dry and warm-wet seasons. This indicated that each population was adapted to its local environment.

Opis:
The purpose of the research was to determine the impact of selected sociological factors related to the readiness for hypothetical financing the most important public functions of forest and forest management (WTP, willingness to pay). In direct surveys carried out in August 2008 by the nationwide research center on representative random sample of 500 residents of Warsaw we used the contingent valuation method (CVM) format of questions with a debit card. The result of determining the values of forest and forest management public benefits with the CVM method (set of values WTP>0 [PLN/year/household]) was analyzed via logistic regression, in which a dependency between the fact of declaring the value WTP>0 (1 – WTP>0 declaration, 0 – WTP=0 declaration) and the selected groups of explanatory variables was assessed. The division of explanatory variables into groups resulted from the survey structure and content of questions, related to different aspects of leisure related forest management. The significance of variables in analyzed regression models was investigated with the maximum likelihood method using Wald's chi−square statistic for the 3rd type analysis. Wald's confidence intervals were designated for regression coefficients in exponential scale, and in order to facilitate the interpretation of results, odds ratios were determined. The logistic regression was performed in SAS 9.3 program with the LOGISTIC procedure. The probability of WTP>0 declaration increased among respondents, who indicated: a) peace and quiet as elements which decide of tourist attractiveness of forests; b) car parks as missing elements; c) that they do not feel well in forests with unsightly tree stand; and d) that they relax better in forests where there are shelters, benches, and roofings.

Opis:
The level of damage to the cell membranes is a sign of aging of the seeds and a decrease in their viability. Conductometric seed testing method indirectly utilizes uncontrolled leakage of ions from seeds with damaged cell membranes to assess their viability. This involves the use of an electrical conductivity of the aqueous solution, in which seeds are soaked. The research was conducted in the years 2011−2014 and aimed at developing the methodology of evaluation of Scots pine and Douglas fir seeds by conductivity test. The aim of the study was to determine the relationship between electrolyte leakage and germination capacity of Scots pine and Douglas fir seeds. 402 samples of Scots pine seed and 90 specimens of Douglas fir seed from all over Poland were tested. The research material was both freshly harvested and stored. Scots pine seeds were obtained in the years 2008−2014, while Douglas fir – 2003−2013 as well as ones stored in the refrigerator for 15 years. Conductivity test and standard seed germination procedure of the analyzed species were used. For both Scots pine and Douglas fir, we noted that, as the electrolyte leakage rate increased, the germination capacity of the seed decreased. So we decided to test whether the vitality of the seeds was determined by means of a conductivity test. The best−fit regression model was determined and the mean expected germination capacity in the viability classes was calculated. 95% confidence intervals for the regression function were also determined. Evaluation of the viability of the seeds by means of the conductometric method is especially useful for seeds requiring a long stratification period (e.g. Douglas fir to determine the potential loss of their vitality. Although the ISTA seed evaluation rules do not require conductivity test for evaluating the seeds of Scots pine and Douglas fir, it may be applicable in situations where it is necessary to perform a rapid assessment of viability before spring sowing.

The aim of the study was to determine the impact of increased forest management due to natural disasters on particular core unit costs. We analysed the direct costs for the Forest District of Wêgierska Górka in the years 2004–2010 based on information from the State Forests Information System (SFIS) database compared with selected forest districts within the Regional Directorate of State Forests in Cracow (RDSF). The forest districts were divided into two groups with two and six forest districts and confidence intervals around the mean were determined and the significance of linear regressions of the considered characteristics was tested. Additionally, the growth rate (decrease) of the unit cost was calculated. Our studies showed that natural disasters affect only certain unit costs regardless of the intensity of the forest management. The increase in unit costs resulted in economic losses in forest management. A full long-term analysis of the economic impact of natural disasters should be done, taking into account the cost of reforestation of destroyed areas which may become apparent only some years later.
