    Opis:
    The radiation exchange drives the plant ecosystems energy balance and provides the energy for photosynthesis, transpiration and plant growth. The investigation on net radiation and its component during vegetation season in relation to the clearness index and sun elevation in a cultivated 31-year-old mountain spruce [Picea abies (L.) Karst.] stand is presented. Downward short-wave radiation – Sd (incident on the spruce stand was the main part of the short-wave radiation balance during the whole growing season (April–October) 2008. The Sd a mount i s seasonally variable factor determined by the duration of solar shine and the atmosphere transmissivity. Obtained value of net radiation (Rn) and downward short-wave radiation (Sd) ratio amounts to 0.61 on average during the growing season 2008 documenting the importance of the downward short-wave radiation in the net radiation of investigated spruce stand.

    Opis:
    The incidence and severity of butt rot were assessed in 12 selected Norway spruce seed stands in the Beskidy Mountains, Poland. A semi-invasive technique of sonic tomography was used for the assessment of rot damage. Stands of different age classes (100–120, 130–150, 160–170 years old) and distinct regions of provenance (Istebna and Orawa) were investigated. Hierarchical analysis of variance was used to determine effects of stand age and stand provenance on butt rot occurrence at a stand level. High incidence of butt rot was noted in all of the studied seed stands (47% to 87% of diagnosed tree samples). Stand age had a significant effect on percentage share of ‘damaged wood’ on the tomogram. The extent of rot damage was rising with stand age, and the largest was observed in the age category 160–170 years. Spruce stands of Istebna provenance were generally more damaged by butt rot than those of Orawa provenance, however, the latter have been growing in forest sites more suitable for spruce in terms of fertility and altitude. Hierarchical analysis of variance did not show a statistically significant relationship between the region of provenance and average share of ‘damaged wood’ on the tomogram. Presented results indicate that for stands growing in similar conditions vulnerability to butt rot is determined by stand age. Further research is needed to separate impact of stand provenance identified with specific genetic constitution of a population from the effect of environmental conditions typical of a given region of provenance.

    Opis:
    The article presents the results of provenance trials carried on the Norway spruce (Picea abies (L.) Karst.), the Siberian spruce (Picea obovata Ledeb.) and hybrid forms of these two species. The trails were laid in 1977–1978 according to wide-scale All-Union program of 1972 year (Prokazin 1972) in the Arkhangelsk, Vologda, Leningrad regions and the Republic of Bashkortostan. The results of the most recent inventory of provenance trials as well as analyses of preservation and growth of spruce progenies with different geographical origin are presented. One of the main factors affecting spruce progeny survival was north-south distance between seed collection locality and test locality. At the time of the study (2010–2012), in the Vologda and Arkhangelsk regions, spruce progeny preservation was higher in the case of mother stands distant to the north. On the contrary, in the Leningrad region and the Republic of Bashkortostan, preservation of northern climatypes’ progenies was lower during the whole period of plantations’ growth. With the change of seed collection locality towards west-east direction, a correlation between progeny preservation and geographical origin factors was non-existent (Vologda, Arkhangelsk regions) or weak (Leningrad region, Republic of Bashkortostan). The most successful growth and the lowest preservation were observed under the conditions of sharp-continental climate, in provenance trials carried out in the Bashkortostan Republic. In the north of Russia, in provenance trials in the Arkhangelsk region there was observed the slowest spruce growth. On the whole, at all the objects under investigation, Norway spruce progenies and hybrid forms with Norway spruce properties showed better growth parameters when compared to those of the Siberian spruce.

    The results of previous studies have shown high breeding values of Beskidian spruce. The aim of the study was to assess the genetic structure of seventeen Norway spruce provenances from the Beskidy Mts. tested in IPTNSIUFRO 1964/68 experiment in Krynica, which survived after massive wind damage on the plots. Polymorphism of five isozyme systems encoded in five loci was determined. The highest value of genetic diversity parameters: mean number of alleles per locus and observed heterozygosity was noted for progeny of spruce from the Eastern Beskidy Mts. (Na = 1.47, Ho = 0.15), and the lowest – for the provenance from the Western Beskidy Mts., Babia Góra massif and the Beskid Sądecki Mts. (Na = 1.27, Ho = 0.12). Mean genetic distance between analyzed spruce provenances was equal to 0.027.

    Opis:
    The experimental plots were located in the middle forest zone (900– 950 m) on two nappes of the flysch Carpathians: Magura (the Ujsoły Forest District) and Silesian (the Wisła Forest District) in the spruce stands of age class 21– 40 years. Serpentinite was introduced in the autumn of 2008 on all plots while other fertilizers (N, P, NP and NPK) in the spring of 2009. Based on the chemical composition of soil solutions collected in lysimeters placed at the depth of 20 cm in the autumn 2008 and the spring and autumn 2009, ecochemical parameters were calculated: acid neutralization capacity (ANCaq), alkalinity (ALK), the degree of soil acidity (Ma%), acidic cations (Ma), saturation of the exchangeable complex of the soil solid phase (Mb) with alkalis, saturation with alkalis (BS), molar relations Ca/Al, Mb/Al, BC/Al. After the winter, soil solutions became acidic, especially in the Wisła Forest District. The saturation of the studied soils demonstrates moderate flexibility of soils in the Wisła Forest District in relation to acid load, and high flexibility of the Ujsoły soils. The opposite trend was observed for the degree of acidity of soils. Acid neutralization capacity and alkalinity of the waters showed significant variations in soil pH even in the case of small variations in the composition of the solution, if they were caused by the inflow of the anions of NO3 - and SO4 2-. After application of the fertilizers, an increase of Mg, Ca and Mb was noted in the soil solution, determined in the overlaying highly acidic organic horizons trough the ion-exchange buffering mechanism of highly protonated functional groups with high buffering capacity. Highly improved content of Mg in a soil, and in some cases – also the content of N, P and K, present potential improvement of forest growth capacity without the hazard of adverse side-effects of liming. Aluminum stress in the spruce is unlikely, while trees in the control plots in the Wisła Forest District may already be sensitive.

    Opis:
    The study was conducted in 2015 in six spruce stands situated in different forest districts administratively belonging to the Regional Directorate of Forests State in Krosno. Each spruce population was represented by 30 trees and assessed in terms of their current health status. Genetic analyses were performed based on shoot samples from each tree using nine nuclear DNA markers and one mitochondrial DNA marker (nad1). The health status of the trees was described according to the classification developed by Szczepkowski and Tarasiuk (2005) and the correlation between health classes and the level of genetic variability was computed with STATISTICA (α = 0.05). Nuclear DNA analyses revealed a low level of genetic variability among spruce populations (only 3% of the total genetic variation (FST = 0.028) and a high variability within populations (97%). The total heterozygosity in all stands (HT) was calculated as 0.646. Based on UPGMA analysis, the most genetically similar populations are spruce stands in the Bieszczady National Park and the Ustrzyki Dolne Forest District, which have the smallest genetic divergence of all populations (DN = 0.0165). Our analysis of the mitochondrial gene nad1 revealed the presence of six different haplotypes “a”, “a1”, “b”, “c”, “d” and “d1”. Comprising 56% of all haplotypes, “a” was the most common showing a predominant impact on spruce migration from the Carpathian area. The analysis based on mitochondrial markers (by Nei) revealed a heterozygosity of 0.525. Based on the observations of disease symptoms, 29% of the trees belong to health class 1,30% to class 2,28% to class 3 and class 4 contains 13% of trees. The comparison between health status and the level of genetic variation in the analyzed stands showed a positive correlation. Spruce stands with better health were also characterized by a greater degree of genetic variability. Since most of the investigated spruce populations shared the mitochondrial haplotype “a”, we have ascertained their Hercynian- Carpathian origin. Only one stand (Cisna) had a high frequency (43.3%) of the Nordic haplotype “c” suggesting that this provenance is derived from the Baltic post-glacial refugium of P. abies in Europe.

    Spruce bark beetle Ips typographus (L.) (Col.: Curculionidae, Scolytinae) outbreaks occur in managed and protected forests alike, but although known of for a long time, management and control of this insect is a controversial subject due to the forests’ diverse nature and protection status. In this paper, an overview of the bark beetle, conditions leading to outbreaks, natural enemies and the efficiency of control measures is presented and put into perspective with regards to the current controversies concerning outbreak management. The Białowieża Primeval Forest is central to this discussion, because the area remains divided into parts with different nature protection statuses. Ideas concerning the current but also future outbreak progress and possible issues with the management of natural resources in this area are presented.

    Opis:
    The main aim of this paper was to characterize Norway spruce clones in terms of bud burst, flowering and morphological features. Observation and measurements were carried out in the Norway spruce seed orchard of the Bielsk Forest District in the north-eastern part of Poland. The seed orchard was established in 1989 and consists of 428 grafts of over 37 trees from the Białowieża Primeval Forest. An assessment of bud burst, stem forking, stem form, crown width, branch thickness, vitality, flowering and fructification as well as diameter measurements was done in 2013 and 2014. The results showed variability of morphological features among different clones as well as within individual clones. Differences among clones in spring bud development, stem form and branch thickness were statistically significant. Additionally, a positive correlation between male and female flowering was observed. The research also confirmed an influence of the healthiness of the grafts on seed production with trees in a weakened state producing more seeds.
