    Opis:
    The paper outlines the history of international provenance experiments on Norway spruce (Picea abies (L.) Karst.) conducted in Poland, starting from the first attempt at establishing trials in 1938, which was interrupted by the war. The most important experiments so far have been the IUFRO 1964/68 and IUFRO1972 Inventory Provenance Tests with Norway Spruce.

    Opis:
    Provenance trials were designed to analyse the quantitative responses of tree species to environmental variables found in different experiment location. However, we have still limited knowledge how natural and artificial selection affects genetic variation of the species populations gather in such experimental sites. We have used bulked DNA-based RAPD and ISJ analysis to investigate genetic diversity and differentiation of Scots pine populations from two Polish locations of IUFRO 1982 provenance trial placed in Kórnik and in Supraśl. Applied categories of DNA markers differed in terms of revealing genetic diversity of the species. Ten RAPD primers applied in the study yielded a total of 75 bands, of which 21 (28%) and 15 (20%) were polymorphic in Kórnik and in Supraśl, respectively. Six ISJ primers revealed 42 bands of which 4 (9.52%) and 14 (33.3%) were polymorphic in Kórnik and in Supraśl, respectively. The genetic diversity and differentiation was low, as expressed by He=0.071 and He=0.085, and by genetic distance values which ranged from 0.0 to 0.240 (on average 0.081) and from 0.017 to 0.188 (on average 0.094) for Kórnik and Supraśl, respectively. Location of provenance trial appeared to have a significant influence on revealed level of genetic polymorphism and pattern of interpopulation differentiation. However, genetic structure found for analysed Scots pine provenances from IUFRO 1982 in Kórnik was also confirmed for Supraśl experimental site. In the light of available data we also discussed the influence of historical migration routes and gene flow on observed genetic variation of the species.

    Opis:
    The paper presents the results of research on the genetic variability in the growth characteristics and plasticity of Polish provenances of Norway spruce, tested on thirty plots established in Europe and Canada in the IUFRO 1972 provenance experiment. Special consideration was devoted to the plots in Poland, especially in Knyszyn. The variability in the growth and quality characteristics of the provenances, found at experiment level, is high (within 6.099 standard deviation units). At provenance level, it ranges between 4.674 for Kartuzy and 2.192 for Rycerka Zwardoń. This indicates that the performance of the provenances depends much on environmental conditions. Although no provenance can be considered adaptable to any conditions thatmay occur in the cultivation of spruce, the Istebna Bukowiec and Zwierzyniec Lubelski provenances, having a very high breeding value and high plasticity, may be recommended for a wider use in reforestation.

    Opis:
    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 paper presents the results of research concerning the genetic variation in the growth traits and phenotypic plasticity of Norway spruce populations from the Silesian Beskid Mts and compares them with those of twenty Polish spruce provenances planted on thirty plots established in Europe and Canada in the IUFRO 1972 provenance experiment. The Silesian Beskid spruce is represented by six populations from the Wisła and Ujsoły Forest Districts. The variation in the growth traits of all populations discussed (data from all plots) is 6.009 standard deviation units. At population level this variation is also comparatively high and ranges between 4.674 for the Kartuzy spruce and 2.1920 for the Rycerka Zwardoń spruce. The Silesian Beskid spruce populations are not homogeneous but they belong to the populations with a high or moderate growth rate. The Istebna Bukowiec spruce performed the best on most plots. Only on Finnish and Canadian plots the growth traits of this population were below the average.

    Opis:
    In connection with the decline of spruce stands on the Krynica plots of IPTNS-IUFRO 1964/68, observed in the last decade and attributed to the so-called spiral disease, an attempt was made to determine whether the current health condition of trees is influenced by genotype (provenance). As shown by preliminary observations, the spruces differed in the degree of survival depending on provenance. The inventories of died or broken trees to be removed during the sanitary cutting, made in the years 2000, 2003, 2004 and 2008, yielded also information about the number of spruces that remained in the blocks of the experiment for each provenance and provenance region by Krutzsch (1968). Analysis of variance showed that genotype (provenance) has a statistically significant effect on the survival of trees. In the years 1999-2008, spruces from region 21 (Bohemian Forest) displayed the poorest survival rate in the conditions of the Beskid Sądecki Mts., while those from region 80 (Eastern Siberia) survived best.

    Opis:
    Due to the deterioration in the health condition of Norway spruce on the IPTNS-IUFRO 1964/68 observation plots in Krynica (Poland), there was an urgent need to determine the cause of the decline in order to design preventive measures. For this purpose, a health inventory was carried out in the years 2002 and 2003. This included an assessment of the condition of crowns in 144 trees and a thorough examination of 29 felled trees. It was found that individual trees or groups of trees have declined in some blocks of the experiment. The tops of some trees were dying and the crowns were getting transparent. The discolouration (turning brown) of needles was quite common and even green needles were shed. Some of the roots showed symptoms of necrosis and died. Seven taxa of pathogens were isolated from the diseased roots and trunk parts of spruces, among them Phytophthora citrophthora, Fusarium avenaceum, F. solani and Trichoderma. The number of diseased trees was related to provenance. The provenances Babenhausen (Germany), Frantiskovy Lazne (Czech Republic), Traunstein 1/4 D, 6 A, B, 7 A (Germany), Wundsiedel-Weissenstadt (Germany), Mestwinowo (Poland), and Magland (France) proved to be more susceptible than others to fungal pathogen attack.

    Opis:
    The juvenile height growth of Norway spruce (Picea abies (L.) Karst.) was studied in 1095 spruce provenances included in the IUFRO inventory provenance test of 1964/68. Trees growing on the experimental site established in Krynica in the Beskid Sądecki Mts. (Carpathians) were measured at ca. 3-year intervals in the period 1969-1988, from the age of 6 years (i.e. 2 years of planting) to 25 years. The variability of tree height in this spruce population was assessed on the basis of the means expressed in units of standard deviation, calculated for each provenance and each geographical region of Krutzsch in successive years of measurement. Using the standardised units made it possible to characterise the dynamics of spruce growth in provenances from 95 geographical regions representing the whole European range of the species. The effects of geographical region, tree age and their interaction on the variability of height growth within this range were estimated using multi-way analysis of variance with replicated measurements. The regions showing similar spruce growth trends were grouped by using hierarchical cluster analysis. The results on the juvenile dynamics of height growth showed that spruce provenances from various geographical regions of Krutzsch differ significantly in their genetic reactivity. Based on this, several groups of regions were identified: (1) regions with average or weak but stable spruce growth characterised by no significant effects of age or genotype × age interaction in the whole measuring period, or regions with height growth improving with age; (2) regions of spruce provenances constituting a selection elite, with very good height growth in the whole measuring period or in its later part, characterised by no G × A interaction; (3) regions with varied genetic reactivity of height growth dynamics in the juvenile period, and regions of Scandinavian populations with poorest height growth in the whole measuring period. The studies proved that spruce provenances from the regions of Štiavnické Pohorie, Low Tatras (Slovakia), Masurian Lakeland, Augustów Lakeland, Podlasie, Silesian Beskid Mts., Beskid Żywiecki Mts. (Poland), Jutland (Denmark), Bihor Mts., Transylvania, and Eastern Carpathians (Romania) have a high selection value.
