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:
Two field inoculation experiments were conducted to study intraspecific variation in vertical spread of the P-, S- andF-IS-group isolates of Heterobasidion annosum in stems of Pinus sylvestris, Picea abies and Abies alba. Host-plants were inoculated with four isolates of each IS group after 10 mm long wounds made with a sterile knife (experiment 1) or 3 mm diameter radial holes made with a drill (experiment 2). On pine, the P-group isolates were more virulent than S andF isolates in terms of infection frequency, mortality rate andvertical spread in sapwood. The S isolates had higher incidence of infection and extensive growth on spruce than on pine. The F isolates were significantly less virulent on pine andspruce than on fir. Vertical spreadof all IS groups on fir was similar. In spite of between-strain-within-IS group variation in vertical spreadon each host, the study provided strong evidence for the occurrence of intraspecific differences in the host preference. In the interspecific analysis with three hosts, the isolates, IS groups andhost × strain andhost × IS group interactions accountedfor most of the explainedvariation, while host-plants accountedfor the smallest portion of the variance.

Opis:
In the years 1994-1997 a gradation of the spruce bark beetle, caused by the drought and the high temperatures prevailing in the previous years, took place in Białowieża Forest. To make an evaluation of the forest's condition after the gradation, a system of a permanent study plots was set in the Strict Protection Area of Białowieża National Park. In the present article are summarized observations from 388 plots. We analysed the proportion of spruce in a lying wood, a tree stand and a new generation of the tree stand, in relation with the character of the forest habitat and the tree stand development phase. The results of the observations confirm the hypothesis that the process of the spruce retiring from fertile habitats has been lasting for several years. The most extensive changes caused by the spruce bark beetle were noted in young mixed/coniferous forest stands.

Opis:
A local tree ring chronology for Norway spruce from the Ormtjernkampen National Park in Norway has been developed for the years 1808−1996. The widths of annual tree rings are shown as absolute [mm] and standardised values. The dendroclimatic analyses have demonstrated that high June−July air temperatures and atmospheric precipitation in January have a stimulatory effect on ring formation. The high air temperatures of April in the current year and of June and September in the year prior to ring formation have a limiting effect on radial increment.

The analyses pointed to the low accuracy of commonly used Radwański tables worked out by Czuraj [Czuraj 1998], which are currently being edited.

Opis:
The paper provides information concerning the growth of pine, spruce, oak, beech and fir stands based on the research conducted by the European Forest Institute in a number of the European countries and in Poland. Noteworthy i.a. is the increase in volume increment of spruce and pine in some stands in Germany up to 250% of the values given in the yield tables. Since the early fifties of the past century beech and sessile oak in Bavaria have exhibited an increase in the height growth and volume increment. Their values markedly exceed those provided in the tables. Fir, similar to spruce, pine and beech shows the reduction in the increment and dieback in the regions under heavy industrial pollution. However in other regions under the impact of air pollution the response of pure and multispecies stands with the share of fir was positive. In Poland, a rapid decline in the dbh increment in three tree species (fir, spruce, pine) in the seventies was greater than in the sixties. In 1981−1989, fir showed a favourable growth in diameter; this positive tendency was noticed in the whole range of fir distribution in Poland, though the increment did not return to the level before its decline. The pine increment regenerated after 1990. The poorest increment was found in spruce in the eighties following its collapse in the seventies (Żywiecki and Śląski Beskid).

Opis:
In the Czech Republic, Norway spruce has a natural representation in all forest altitudinal vegetation zones, in some of which (FAVZ 1, 2 and 9), however, it is scarce. The three basic climatic ecotypes of spruce identified in the Czech territory, i.e. an upland ecotype, a higher elevation ecotype and a mountain ecotype, can be characterised on the basis of the forest altitudinal vegetation zones of their origin. The paper presents the breeding work completed so far and all the breeding programmes implemented for Norway spruce, including projects worked out for the Krkonoše National Park.

Opis:
The effects of drought stress, stress by increased nitrogen depositions and the combined effect of the two stress factors on the growth of Norway spruce Picea abies (L.) Karst. were studied in two stands. The drought stress was induced by reducing atmospheric precipitations by 60% and the increased nitrogen depositions were simulated by repeated applications of ammonium sulphate at a rate corresponding to 100 kg N ha–1 year–1. All stress factors under study affected the height increment of the above-ground part, the length and colour of needles, and the biomass, vertical distribution, functionality and mycorrhizal infection of fine roots. The root system responded to the simulated stresses right from the the very first year of their action, exhibiting a greater damage than the above-ground part of the plant. Drought acted as a stress factor stronger than the nitrogen depositions themselves. The strongest impact was recorded in the simultaneous influence of the stress factors.

Opis:
The study analyses the transfer of F-, Cl-, NO3-, SO42-, Na+, K+, Ca2+, Mg2+, Fe2+, Mn2+ and Zn2+ from bulkprecipitation to throughfall, soil surface flow, vertical flow and intercover flow of water (gravity lysimeters at 20 cm soil depth) in spruce stands of different age classes (1st, 2nd, 5th, 6th), and the amount of these ions flowing out from the Potok Dupniański catchment in the Silesian Beskid Mts. The results cover the year 2000. The concentration and amount of SO4 2- in throughfall systematically increased and the pH value decreased with the age of the stands and with successive elements of the ecosystem. The NH4+ ion was probably absorbed in the canopy, which caused a washout of K+, Mn2+, F- and SO42- in the vegetation season in older stands. In the winter season, Fe2+, Mn2+, Na+ and K+ were washed out from the youngest stands (1st age class), whereas F-, NO3 -, SO42--, K+, Ca2+, Mg2+, Mn2+ and Fe2+ – from older canopies. Decomposition of the organic matter caused a rise in water acidity and an increase in the concentrations of all the analysed ions; their leaching, however, was low (under 1%). Water from intercover flow contributed to an increase in the amount of water and the concentration and amount of ions and to a further decrease in water reaction at a soil depth of 20 cm. All the anions and cations flowed away with water penetrating vertically and horizontally. Considerable amounts of ions, especially SO42-, Na+, K+, Ca2+ and Mg2+, were carried beyond the reach of the main mass of the root system and then out of the catchment, which may adversely affect the development and health of spruce stands.
