    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.

    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 results of research into leaf stomatal variability of five European beech provenances originating from Austria, Bosnia and Hercegovina, Germany, Romania and Serbia are presented in this paper. Aim of the study was to investigate how stomatal traits of provenances originating from different environments change in response to drought stress and to assess the phenotypic plasticity of the stomatal features investigated. The study was conducted during two different years, characterized by contrasting weather conditions (2010 and 2011). Two-way ANOVA revealed that provenances differ significantly in terms of stomatal density (SD), width of stomatal aperture (Wb), potential conductance index (PCI) and relative stomatal pore surface (RSPS), during both seasons. In a dry year (2011) all provenances significantly increased stomatal density by between 16.1% (Hasbruch – DE) and 21.9% (Cer – SRB). Guard cell length (LA) was not statistically different among provenances in either year (2010 and 2011), even though LA decreased in the dry year (2011) in all provenances. Reaction norms were steep in most of the parameters suggesting the possibility of a plastic response of provenances toward changes in soil water regime, influenced by the prevailing weather each year. Phenotypic plasticity indices were the highest in regards of SD, PCI and RSPS, indicating that these traits would be good candidates for improvement in breeding programs aimed at selection of drought resistant.

    Opis:
    Provenance trials with forest trees provide valuable information about growth and adaptability of populations often transferred over large geographical and climatic distances. In this study we evaluated growth and survival of 19 Scots pine (Pinus sylvestris L.) populations representing most of the natural range of the species in Europe, growing in a 30-year-old provenance trial in the northeastern Poland. We used cluster analysis to investigate differentiation among those populations in growth and survival. We also used published data on needle morphology and allozyme and DNA marker variation for those same populations to compare groupings of populations based on growth and needle traits and markers. We found significant variation among tested populations in all investigated traits – the largest variation was found for stand volume which integrates information on growth and survival. Variation in growth traits was related to the latitude of population origin with populations from the latitudinal band between 49° N and 54° N showing the best performance. Populations originating from both north and south off of that region showed lower productivity, which for southern provenances resulted from their particularly low survival, reflecting the lack of adaptation to the environment of the research site. Grouping of populations based on growth traits revealed three clusters corresponding to the three latitudinal regions – northern, central and southern. Needle morphological traits were not appropriate as markers of productivity. Clustering of populations based on needle morphology, and especially based on biochemical and molecular markers, did not correspond to the grouping based on growth traits.

    Opis:
    The study evaluated the sensitivity of European larch (Larix decidua) of two provenances to thermo−pluvial conditions on the provenance plot located in Sękocin Stary (52°05‵ N, 20°51‵ E, 125 m a.s.l.). The studied larches originated from Pelplin (lowland, northern Poland, 50 m a.s.l.) and Szczytna (upland, southern Poland, 525 m a.s.l.). The trees of both provenances differed in terms of their quantitative and qualitative breeding characteristics. The trees originated from different climatic regions whose climate was also different from the climate of the provenance plot. Values of the size of the radial increments measured at cores extracted from the trees were the measure of their sensitivity to the climatic factor. The cluster and principal component analyses were used to classify the trees according to their features of the short−term rhythm of the radial increments. The response function and pointer years analyses were used to evaluate climate−growth relationships. The results of the study show the trees of both provenances have similar sensitivity to the thermo−pluvial conditions in the previous September, the temperature in March and the precipitation in May of the year of tree−ring formation. The larches of Pelplin provenance, in contrast to the trees of Szczytna provenance, were sensitive to the low temperature in February and the low precipitation in the growing season. These features could be one of the causes of the lower incremental abilities of the trees of Pelplin provenance. The larches of Szczytna provenance had higher frost tolerance in February and drought tolerance in summer.

    Opis:
    The study objective was to verify the hypothesis on ecotypic variation in beech and ineffectiveness of transferring its reproductive material over larger distances. Beech nuts were collected in the autumn of 1990. Experimental sites were established in the Baligród and Oleszyce forest districts (SE Poland). On single plots of 18.00×13.75 m (247.5 m2), a total of 110 three−years−old seedlings were planted in a 1.50×1.25 m spacing in autumn 1993. Single row of mountain ash was left between the plots. In the period of 1994−2016 a series of analyses was conducted concerning adaptation, growth, phenological and qualitative traits. Height was measured on all trees using a measuring stick, except for the year 2016, when hypsometer was used to measure approximately 20 heights and remaining ones were determined based on the height curve. Results were analysed using univariate analysis of variance based on the random model, followed by Duncan’s multiple range test for each experimental site and year of the study. For 2016 ordering of populations in each of the experimental sites was compared using Spearman’s rank correlation test. In terms of survival rates in Oleszyce site the local provenance from Oleszyce proved to be superior. In all the years of the measurements it was characterised by the highest survival rate. In this respect the Komańcza and Lutowiska provenances from the Bieszczady Mountains turned out to be the worst ones. In the experimental site in Baligród, the Barlinek and Połczyn provenances outranked the others in terms of their survival rates, while in 2016 it was the population from Komańcza. Tree height effects in Oleszyce site showed that the local population from Oleszyce grows best, while the Pomeranian population from Jamy was also exceptional. The Bieszczady populations (Komańcza and Lutowiska) are characterised by the worst growth traits. In the experimental site in Baligród, the local Baligród population is characterised by poorest growth, similarly to the other ones from the Bieszczady. In terms of growth, the Western Pomeranian population from Gryfino is exceptional. As far as all the evaluated traits are concerned the investigated populations exhibit considerable variability, as no geographic ordination could be found. It was confirmed that imported populations, even from long distances, may exceed local populations in terms of their adaptation traits and growth rates.
