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 quality assessment of spruce seeds consists mainly in determining their germination capacity, including germination rate (speed), but also purity and weight. Internationally recognised methods are listed in the ISTA Rules for Seed Testing which also specify test conditions. Some countries such as Poland use modified methods. Apart from providing information about the purity of a species, purity testing can also identify the proportion of winged seeds in each seed lot. Germination tests yield data on the maximum germination potential of a seed lot which are used to compare the quality of different lots and to establish the field sowing values. This paper presents the methods used for assessing the quality of Norway spruce seeds, and discusses their advantages and disadvantages and the problems that need further investigation.

Opis:
Two provenance experiments with Norway spruce in Slovakia were used to reveal trends in the behaviour of provenances after their transfer. Regressions between the average height and survival of provenances and the differences between the geographic and selected climatic characteristics of the place of origin and provenance plots were significant for most of the characteristics tested. Data from the experiment with Polish and Slovak provenances from 1972 indicated that transfer into warmer regions with a longer vegetation period results in improved height growth and survival, with the exception of survival at initial stages. The experiment from 1964 with a broader altitudinal range of provenance plots, but with unadjusted latest measurements at individual plots available, revealed the best height growth of Slovak Norway spruce provenances after their transfer to sites with the mean annual temperature approximately 1°C higher and with the vegetation period 12 days longer than at places of origin. Transfer into lower altitudes, a warmer climate and a longer vegetation period improved survival. In both experiments, transfer to areas with increased rainfall had a negative effect on growth, which is probably associated with the fact that provenances are not able to exploit additional precipitation for the growth in areas with a colder climate and a shorter vegetation period.

Opis:
The objective of the study was to determine differences in the response of trees of three species: Pinus sylvestris, Picea abies and Pseudotsuga taxifolia to environment pollution with fluorine compounds. The amounts of free and complexed fluorine (FA) and total fluorine (FB) were determined in the needles of trees of the three species growing in a polluted area and in an area considered free from pollution. The results of this study showed that Douglas fir is a greater sensitivity to fluorine compounds than Norway spruce and Scots pine, despite its high resistance to fluorine absorption. Estimation of the degree of environment pollution on the basis visible injury and the content of fluorine compounds in needles is discussed. The results were supplemented with observations of lily of the valley (Convallaria maialis) – a plant particularly sensitive to injury by fluorine compounds.
Celem badań było określenie zróżnicowania w reakcji drzew sosny zwyczajnej, świerka pospolitego i daglezji zielonej, na wpływ związków fluoru. Analizowano zawartości fluoru wolnego i związanego kompleksowo (FA) oraz całkowitego (FB) w igłach drzew rosnących w terenie skażonym oraz uznanym za wolny od wpływu zanieczyszczeń. Wyniki tych badań wskazują na większą wrażliwość daglezji niż świerka i sosny mimo, że charakteryzuje się ona znaczną odpornością na pochłanianie fluoru. W pracy dyskutowana jest możliwość wykorzystywania obserwacji widocznych objawów uszkodzeń i pomiarów zawartości fluorków, do oceny stopnia skażenia środowiska przez związki fluoru. W badaniach dodatkowo uwzględniono konwalię – jako roślinę wskaźnikową na ten typ zanieczyszczeń.

Opis:
In this paper, we describe the assessment of Norway spruce (Picea abies Karst.) trees health by the use of low-altitude aerial photos taken in the first half of June, so during the growth of trees and extensive changes in their crowns. Another differentiating factor is the composition of the stand, where there are trees grown from seeds collected from several remote locations. Images were taken in RGB and IR ranges and processed to orthomosaic, which was used to assess the condition of the trees. The aim of the study was to evaluate the possibility to acquire on this way reliable information about the condition of the trees, by comparison with the results of field research conducted in parallel. The differences between the assessments of trees damage in the field and on the basis of ortomosaics are not large, in all cases less than half a degree. The differences in results from field observations, and the picture are slightly greater in the case of trees observed on the discolored parts of orthomosaics. It is noticeable that the observer has difficulty in these conditions in the appropriate reading of degrees of damage. Although we used images taken in the unfavorable season (intensive development of trees) and related to the forest made up of trees of different origin, which is expressed at different rates of phenological events, the obtained results are with high compliance between field assessment and on the basis of the image. In the case of trees located outside the discoloration assessment results achieved on the basis of pictures were similar to the degree of damage reconized in field.

Opis:
The paper provides a detailed characterisation of Norway spruce stands in the Ukrainian Carpathians. The majority of natural spruce stands in Ukraine occur in Polesie, while artificial regeneration is spread all over the country. The most densely forested part of Ukraine is the Carpathian region with 41.1% of forest-covered area (2.1 million ha). Spruce-dominated stands occupy about 700 thousand hectares (30%) of the forested area of the state forest fund in the Ukrainian Carpathians, and another 10% of the mixed forests contain 10 to 30% of spruce. Besides pure spruce stands, there are beech-spruce, beech-fir-spruce, and cedar-spruce stands. The most productive stands (750-900m3 stem wood per ha) grow in the middle and lower parts of slopes at 1100-1200 m a.s.l. which have favourable soil and climate conditions. Since the second half of the 20th century, spruce stands in the substantial part of the Ukrainian Carpathians have declined under the influence of complex anthropogenic and natural factors. Although the present condition of most spruce forests in this region remains satisfactory, the degradation processes and the ban imposed in 2006 on planting spruce on non-spruce forest sites (in state forests) may decrease their area in the longer term.

Opis:
Over 50 populations of Norway spruce from Bavaria were analysed at 23 isozyme gene loci. The mean genetic distances between these populations were quite small. A geographical grouping could not be observed, and discrimination between provenances from high and low altitudes was not identifiable using this marker type, either. The only difference between spruce populations from South Bavaria and those from Northeast Bavaria is in the presence of some distinct rare alleles. The highest values for the genetic diversity were detected for spruce stands in Northeast Bavaria (Frankonian Forest). Using STS markers, further genes of the nuclear genome of Picea abies can be dealt with. The genetic differences found on the basis of ten STS markers between different Picea abies seed lots and/or seedling populations are generally 2-3 times greater than those found by means of isozyme gene markers. DNA markers turned out to be an appropriate and substantial addition or even more a suitable alternative to isozyme markers for analysing genetic variation and testing provenance identity. Their advantages consist in a markedly wider variation as well as in the enlarged genome segments investigated.

This study dealt with the species distribution and frequency of ophiostomatoid fungi associated with the bark beetle Ips typographus on Norway spruce and Scots pine in north-eastern Poland. At all locations high spruce bark beetle damage has occurred in 2002-2003. Fungi were isolated from beetles and from brood systems of trees infested by the spruce bark beetle. The ophiostomatoid fungi were represented by 13 species. A similar spectrum of ophiostomatoid fungi as that recorded from Picea abies was associated with I. typographus on Pinus sylvestris trees. The most frequent ophiostomatoid species isolated from beetles, phloem and sapwood of Norway spruce were O. bicolor and O. penicillatum. The frequency of occurrence of ophiostomatoid fungi varied significantly among the examined locations. O. bicolor was the most frequently found species on Scots pine infested by I. typographus. The potential role of ophiostomatoid fungi in the epidemiology of I. typographus is discussed. Additionally, we also recorded how the ophiostomatoid fungi associated with spruce bark beetle could grow into phloem and sapwood of Pinus sylvestris trees.

Opis:
The work outlines the directions in the past and present research into the variability of Norway spruce in Poland, and presents the results of provenance experiments concerning the genetic and breeding value of provenances tested in the Polish range of spruce distribution. The Istebna race proved to have a good value, however, so far only the progeny of single stands have been tested. It is thus necessary to determine the range of distribution for this race. The altitude of the location of mother stands significantly correlates with the genetic and breeding value of their progeny cultivated at different altitudes. This suggests that the altitude and exposure of plantations to be established in mountain forest belts should be specified for individual provenances (altitudinal zoning). New inventory provenance tests should be run under varied site conditions to assess both the genetic value and plasticity range of the provenances. In view of the biotic and abiotic threats facing spruce, there is a need to work out detailed programmes designed to preserve its genetic resources in gene banks and in vivo archives.

Opis:
In the last decades, clone testing has become an important component of the long-term breeding and seed orchards for Norway spruce in Sweden. For more than three decades, considerable resources have been spent on testing clones intended for clonal forestry, but the Swedish forestry never saw it worth to pay the added cost involved in the added gain. The efforts, however, resulted in many clone trials and developments in the technique for clone production and propagation. Theoretically, clone testing is faster and cheaper than progeny testing and more reliable than selecting individuals forwards. Nowadays, the main line in long-term breeding is to make crosses between the best trees and test-cloned full-sibs as a recruitment population for long-term breeding and seed orchards. Since controlled crosses are a bottleneck for long-term breeding, a possibility is to rely on wind pollination (Breeding Without Breeding; BWB) in trials for testing clones. The seed parent is known, and that the pollen parent is a desirable genotype can be checked by molecular markers. BWB has the potential to eliminate the waiting time between selection and recombination, which is particularly important in a late and irregularly flowering species such as Norway spruce. Clone testing ensures that the breeding values are known from the same tests as those used for BWB. Another option for BWB is to place in seed orchards a few ramets of clones belonging to the breeding population, but normally not deserving such a use, with the hope that their presence will make it possible to rely on wind pollination to recombine the whole breeding population.

Opis:
The abundant flowering, observed in 2004 in a model outbreeding seed orchard established in Kórnik, Poland, promoted crossing between clones of five geographically distant populations of Norway spruce. The clones were selected from a group of ca. 1100 provenances participating in the international IUFRO 1964/68 experiment and performing best in terms of growth traits and adaptability. In the seed orchard, 91.3% of clones and 64.1% of grafts produced female and/or male strobili. Statistically significant differences between the clones were only found in the number of mature cones produced. The mean number of mature cones in individual clones was also significantly correlated with the latitude of the place of origin of maternal populations (r = 0.88, p = 0.047). The nearly equal percentages of clones representing each of the five populations in the outbreeding seed orchard (from 23.2 to 17.5%) resulted finally in the highly unequal production of full seeds by each population (from 62.9 to 0.7%). These data provide evidence to suggest that the level of genetic diversity in the progeny, expected from the number of growing clones, diverges from the level resulting from the contribution of clones to the full seed production which is an effective measure of the genetic composition of progeny. To avoid this divergence, an outbreeding seed orchard could be established with unequal proportions of clones from different provenances, considering the knowledge of their flowering phenology, and individual variation in flowering and cone production.

Opis:
At present, Norway spruce stands occupy 22% of the total forest area in Lithuania. Most of them are located in the northeastern highland (Žemaitija) and the central part of the country. 25% of the spruce-dominated stands are pure, the rest are mixed. Natural calamities like storms, droughts, and pests cause substantial damage and occur quite frequently. About 40 thousand ha of stands are cut after each storm. The mean wood yield of the spruce stands is 304 m3 ha-1, and the current annual increment is 6.2 m3 ha-1. The climatic conditions of Lithuania are variable enough to cause differentiation of habitats. For Norway spruce, 6 provenance regions have been established. The national gene conservation programme is based on (a) in situ genetic reserves, seed collection stands, and selected genotypes, and (b) ex situ clonal archives, seed orchards, experimental plantations, and gene bank collections. The present-day breeding of Norway spruce comprises family tests of populations for individual and population selection, and plans for inter-population hybrids. A strategy for Norway spruce breeding has been approved for the years 2004-2013. There is a genetically diverse material for future breeding: long-distance provenance tests, and population and family tests. Assessments of two provenance tests (aged 9 and 17 years) in central Lithuania revealed superior performance of central and northeastern Polish provenances: superior height, good stem quality, and late bud-burst in spring. This may be attributed to the favourable effect of transfer: avoidance of spring frosts (late bud-burst and good stem quality), and utilisation of the later part of the growing period for growth (late bud-set and superior height). Norway spruce is a climax species with different domestic and Darwinian fitness. Therefore, we suggest that the domestic fitness of local genotypes may be improved by introducing a few Polish clones in Lithuanian breeding populations.

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.

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.
