Opis:
This study concerned 26 forest stands with Douglas fir situated in Lower Silesia, Great Poland, Pomerania, Warmia and Masuria. Each stand was represented by 24 trees. From each tree an increment core was taken by Pressler’s borer. The principal components analysis showed that the first three principal components accounted for 73% of the variation of chronologies in total. The first principal component was the most convergent with the mean air temperature curve for January–March, the second with the total precipitation for June–August, and the third with the mean temperature for June–August. The first principal component always integrated the chronologies and decided on a similar rhythm of changes in the tree-ring widths. The annual variation of tree-ring widths was also affected by precipitation in summer (June–August), but this differentiated the chronologies. This was reflected by the dispersion of chronologies in respect to the eigenvectors of the second principal component. The third principal component also differentiated the chronologies. Separate groups were formed by the most eastern and the most western localities of the territory under investigations. Thus the Douglas fir growth reactions were mainly affected by the thermal and pluvial conditions of summer and, to a lesser, degree by the thermal conditions of winter. On the basis of these results it was possible to distinguish the dendroclimatically homogeneous regions in western and northern Poland.

Opis:
The objective of the study was to analyse the site index (SI) of Douglas fir (Pseudotsuga menziesii) stands in relation to the forest habitat type, soil type and relief characteristics. We utilised infor− mation available in the Information System of the State Forests in Poland that included selected parameters describing habitat conditions and dendrometric characteristics of Douglas fir stands. In total, processed data referred to 863 stands with a total area of 1,644.45 ha. As the SI distribution was not consistent with the normal one (Shapiro−Wilk test, p <0.0001) we applied Kruskal−Wallis or Mann−Whitney tests to assess the significance of observed differences. Site index of surveyed stands ranged from 19.9 to 47.8 m, 32.6 m on average (standard deviation of 3.3 m). Douglas fir in northern and southern Poland characterized by higher SI than in western and south−western part of the country (HK−W=83.5; p<<0.001; fig. 2). Forest habitat type significantly distinguished analysed stands (HK−W=30.1; p<<0.001). The highest SI values were observed for mixed deciduous habitats (fig. 3). For more fertile fresh deciduous habitats Douglas fir achieved slightly lower site index, while the least fertile mixed coniferous habitats are characterized by significantly lower SI. Habitat moisture variant had no significant effect on the average SI values (HK−W=2.6; p=0.269). The highest values were found in strongly fresh habitats (32.8 ±4.1 m), while the lowest in the humid variant (31.7 ±3.4 m). We found significant influence of soil type (HK−W=23.2, p<0.001) even though the average SI values for each category were relatively similar (fig. 4). The highest values were observed for Cambisols (33.3 ±3.7 m), while the lowest for Arenosols (32.1 ±3.0 m). Particle size distribution is an important factor for Douglas fir site index (tab.). We found that the heavier material (the higher the content of silt and clay), the significantly higher SI values (HK−W=16.9; p=0.001). Mean SI for stands growing on former farmlands (32.0 ±3.3 m) and on forest areas (32.7 ±3.3 m) were not significantly different (ZM−W=1.73; p=0.084). There was no significant effect of the relief forms on site index surveyed Douglas fir stands apart from the fact that stands growing on slopes are characterized by significantly higher SI (ZM−W=1.99; p=0.047).

Die-back of grafts in the clonal seed orchards of Douglas-fir (Pseudotsuga menziensii (Mirb.) Franco) in Poland and attempts at producing seedlings of this species by autovegetative propagation

Opis:
So far, experience in the existing clonal seed orchards of Douglas-fir indicates that grafts of this species are short-lived. According to research carried out in North America, incompatibility between the grafted scions and the rootstocks happens during the whole period of growth and development in clonal seed orchards of Douglas-fir. A similar phenomenon occurs in the clonal seed orchards of Douglas-fir in Poland. The extent of die-back of grafts was examined in three existing oldest units in the Forest District of Gniewkowo (founded in 1992-1993; 2.80 ha), the Forest District of Leżajsk (founded in 1995, 4.22 ha) and the Forest District of Łopuchówko (founded in 1993, 7.43 ha). In all these areas, losses due to die-back ranged from a dozen to a few dozen per cent. Die-backs in the clonal seed orchards in the Forest District of Gniewkowo and in the Forest District of Łopuchówko are now reduced to as much as about fourty per cent of grafts. Analyses of die-back in all these areas reveal great variation between individual clones, indicating its genetic basis. Research carried out so far has not demonstrated the presence of any pathogens responsible for causing the die-back in the grafts. Some hope to solve the problem mentioned above arises from attempts at autovegetative propagation of Douglas-fir.

Opis:
In fall 2018 and 2019, we assessed colonization by fungi on Douglas fir trees [Pseudotsuga menziesii (Mirb.) Franco], white pine (Pinus strobus L.), and red cedar (Thuja plicata D. Don.) on selected experimental plots of the former Prussian Experimental Station, where nonnative tree species were introduced from North America over a century ago. The presence of sporocarps on trunks, root collars, and stumps as well as the litter layer in the soil within a radius of 0.5 m around the trunk of the tree was determined. Additionally, the volume of dead wood on the forest floor of the entire plot was assessed. We recorded numerous fungi on trees and stumps as well as in the litter and soil. For the 31 plots in 12 forest districts, we determined 745 sporocarps of 48 taxa, with 335/19 on the wood of P. menziesii trees and stumps, 377/15 on P. strobus, and 33/6 on T. plicata trees. The highest share of trees with various trunk damage levels was found for T. plicata (70.3%) and the lowest for P. menziesii (6.2%). Among the root parasitic fungi, Heterobasidion sp. and Armillaria sp. were found, especially on the collars and stumps of T. plicata and P. strobus; we did not find basidiomata of both pathogens on P. menziesii. The volume of dead wood within the P. menziesii plots averaged 7.1 m3/ha, whereas in T. plicata plots, it was 56.3 m3/ha. We identified 10 taxa that have not been reported in association with P. strobus for Poland (Cylindrobasidium laeve, Dacrymyces sp., Exidia pithya, E. saccharina, Gymnopilus pnetrans, Leptoporus mollis, Mycena sanguinolenta, Tapinella panuoides, Trametes versicolor, and Xylaria hypoxylon) and three taxa (Exidia pithya, Leptoporus mollis, Serpula himantioides) associated with T. plicata.

Opis:
Since the beginning of XIX century a considerable number of Douglas fir populations from North America were introduced to many European countries. In France, Douglas fir is still going to increase significantly its participation in growing stock and wood harvest. There are also some countries (e.g. the Netherlands), where the interest in breeding and silviculture of Douglas fir have been decreased in last decades. The data from the European literature was collected to show a current volume stock, growth increment, gene resources and qualified seed sources of Douglas fir in the outlook of the future role of the species in European forest economy. A short outlook on the breeding programs of Douglas fir working out in several European countries was also presented.
