“…Our analysis and some other foreign studies from Serbia, the Netherlands, and Bulgaria similarly confirm differences in growth among provenances [14,24,[44][45][46]. In our experiment, Yelm (1080) showed the best growth performance, it had the largest average dbh, and performed well against most other provenances (Table 2).…”

“…Recent findings have revealed that several old Douglas-fir stands in Austria originated from areas outside the recommended regions (e.g., Northern California), indicating that additional seed sources may be suitable for Douglas-fir in Central Europe [28]. The provenance with the lowest average dbh in our trial was Merrit (1028), which originates from higher altitudes and latitudes in British Columbia; other provenances from these areas also grow poorly in Serbia [44] and Eastern Austria [49]. In contrast, in northern countries (e.g., the Netherlands), provenances from higher latitudes grow better, and growth decreases with decreasing geographical latitude of origin [24].…”

“…All provenances in our provenance trial with above-average dbh originated from a lower or (in one case) similar altitude to that of the Padež I trial site (580 m a.s.l.). All provenances with above-average growth performance and superb vitality in the experimental trial originated from the coastal range of Washington (WACO region; [33]), which was previously known to be the most suitable provenance source region for plantation establishment in Europe for sites not experiencing a strong continental climate [14,24,[44][45][46][47]. Guidelines for provenance selection in Germany recommend coastal subspecies (P. menziesii var.…”

Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) is a non-native conifer from western North America that was introduced into European forests at the end of the 19th century. Plantations of Douglas-fir in Europe have shown good performance, quality, and resilience to exacerbating climatic conditions. However, all these qualities strongly depend on provenance. A total of 1061 surviving trees of fifteen different Douglas-fir provenances were measured in a Slovenian provenance trial that was established within the framework of the 1966/1967 IUFRO seed collection program. We found significant differences among provenances with respect to survival rate, growth performance, and log quality. The total recorded yield of the 46-year-old stand was 602.9 m3/ha, and the average survival rate was 43%. The correlation of juvenile tree heights in 1985 and their average breast height diameters in 2017 is positive and significant. Based on vitality and diameter, the best performing provenances were Yelm and Cathlamet. The provenance with the best log quality assessed through branchiness is Jefferson (Olympic Peninsula, western Washington). All the most promising provenances for western Slovenia (Central Europe) originate from the low-altitude western coast of Washington (WACO), with the Cathlamet provenance showing the best combination of good growth, survival rate, and log quality.

The morphology, anatomy, ecology and physiology of introduced tree species should be tested in order to confirm their autochthonous characteristics and justify their introduction. Douglas-fir (Pseudotsuga mensiesii Mirb/Franco) is a species with a very wide geographical range of distribution and an extensive altitudinal range. Its natural area of distribution stretches from New Mexico to Canada and from the Pacific to the Rocky Mountains. The species should be tested using the model of provenance tests in order to select the most adaptive and promising provenances to be introduced into new ecosystems of Serbia. This paper deals with the content of magnesium in the needles of Douglas-fir in different provenances originating from Canada. Magnesium is the most important mineral for all living organisms and affects a number of biochemical processes in plants.The research was carried out on fourteen different provenances of Douglas-fir originating from Canada on two different soil types - eutric cambisol and vertisol. All the trees of the study provenances were of the same age and grown under the same conditions on two different types of soil. The determined amounts of magnesium in the needles indicate that there are differences in the ability of certain provenances of Douglas-fir to absorb this element of nutrition from the soil.

Douglas-fir is the most commonly grown allochthonous species in the forests of Europe. Growth speed, adaptive power, favorable wood properties, as well as low sensibility to pests are the attributes that have contributed the most to the success and occurrence of Douglas-fir plantations in Europe. Introduction program of an exotic species includes testing of its provenances in new ecosystems and localities. In Serbia, testing of the genetic potentials of Douglas-fir, native to North America, has begun by seting up provenance trials on several locations. Afforestation with exotic tree species must be justified and it should fulfill the aims of the introduction. Therefore, it is neccessary to test all the traits of the introduced species to show the effects of ecological factors. The aim of this research was to determine the ecological adaptations of Douglas-fir in Serbia by studying its anatomic characteristics. In the paper, the influence of locality conditions on the diameter of resin canals in the needles of different Douglas-fir provenances was investigated on the sites where the provenance tests were set up. A two-way ANOVA was performed, by investigating the effects of site and provenance factors on the diameter of resin canals. Resin canals serve as an important diagnostic taxonomic characteristic in conifers, while resin itself has important physiological and protective role in conifers.
