Opis:
Due to the lack of maintenance, abandoned cemeteries are often incorporated into the landscape. In many cases the information about the age of the cemetery is unavailable. To find out the approximate time of the formation of the cemetery the information recorded in the annual tree and shrub rings can be used. One of the most common tree species, planted for ornamental and symbolic purposes on the cemeteries, are Thuja orientalis and Thuja occidentalis. Alien to the Polish flora, these species adapted well to the local habitat and climatic conditions. The paper presents an attempt to apply dendrochronological dating to determine the age of the abandoned cemeteries in the region of the Great Masurian Lakes, part of the Masurian Lake District (north-eastern Poland). The study included five abandoned cemeteries. In total, 15 cores were taken from the trees. After applying the standard dendrochronological method, local chronologies for the studied species were established. The research indicated that the oldest found specimens - over 70 yrs old - are Thuja occidentalis individuals growing at the Słabowo cemetery. At the other sites the specimens of both Thuja species date back to the 1960s and early 1970s. Compared to the historical information regarding the age and origin of the studied objects, thujas growing there are much younger than the age of the cemeteries foundation. The presented method proved to be very helpful in understanding the time of Thuja occidentalis and Thuja orientalis introduction at the investigated cemeteries.
Porzucone cmentarze w związku z brakiem pielęgnacji często wkomponowują się w krajobraz. Niejednokrotnie brak jest zachowanych informacji o wieku cmentarza. Aby poznać przybliżony wiek powstania cmentarza można posłużyć się informacji zapisanymi w przyrostach rocznych drzew i krzewów. Jednymi z najczęściej występujących drzewiastych gatunków sadzonych w celach ozdobnych i symbolicznych na cmentarzach są Thuja orientalis i Thuja occidentalis. Te obce dla flory polskiej gatunki, doskonale zaadaptowały się do zastanych warunków siedliskowych i klimatycznych. W pracy przedstawiono próbę zastosowania metody datowania dendrochronologicznego do określenia wieku porzuconych cmentarzy z Krainy Wielkich Jezior Mazurskich. Badaniem objęto 5 porzuconych cmentarzy. Ogółem pobrano 15 wywiertów z drzew. Po zastosowaniu standardowej metody dendrochronologicznej, utworzono lokalne chronologie przyrostowe dla badanych gatunków. Badania wykazały, iż najstarsze okazały się być okazy Thuja occidentalis występujące na cmentarzu Słabowo, których wiek wynosi ponad 70 lat. Na pozostałych obiektach rosnące okazy obydwu gatunków żywotników datowane są na lata 60. i początek lat 70.XX wiek. W porównaniu z informacjami historycznymi o wieku i pochodzeniu badanych obiektów rosnące na nich okazy żywotników są znacznie młodsze niż wiek założenia cmentarzy. Przedstawiona metoda okazała się być niezwykle pomocna w poznaniu czasu wprowadzenia żywotników Thuja occidentalis i Thuja orientalis na badanych cmentarzach.

Opis:
Korean arborvitae (Thuja koraiensis) is an evergreen shrub or small tree native to Korea and the extreme Changbai Mountain of China threatened by habitat loss. Due to the limited genomic sources of Ko- rean arborvitae, it is important to explore transcriptome to understand this economically important plant. We used RNA-seq technology to characterize the transcriptome of root, stem and leaf in Korean arborvitae, respectively. Based on the bioinformatics analysis of assembled transcriptome data, transcriptional path- ways and differentially expressed genes (DEGs) were identified. There were 152.26 million reads generated, and 446,568 unigenes with a mean size of 423.51 nt obtained via de novo assembly. Of these, 204,091 unigenes (45.70%) were further annotated by comparison to public protein databases. A total of 63,495 unigenes (14.22%) were associated into 130 pathways by searching against the KEGG database. DEGs analysis identified 11,890, 5,900 and 10,136 DEGs from the comparison of root vs. stem, root vs. leaf and stem vs. leaf, respectively. Besides, photosynthesis, plant hormone signal transduction and metabolism and biosynthesis of sugar and amino acids were changed in different tissues. We obtained 446,568 unigenes in Korean arborvitae and 11,890, 5,900 and 10,136 DEGs from the compar- ison of root vs. stem, root vs. leaf and stem vs. leaf, respectively. These results will aid in understanding and carrying out future studies on the molecular basis of Korean arborvitae and contribute to future artificial production and applications.

Opis:
Rhizosphere is a region of the strongest interactions be- tween plants, soil and microorganisms, which play an important role in plant development. Due to a number of interdependencies, they are main factors determining the health and proper growth of plants. All methods used in agriculture that promote the growth of microbial populations and their biodiversity are beneficial both for cultivated plants and for the environment. Thuja occidentalis cv. Brabant, is a very popular plant in Poland. In the study the effect of mineral fertilizers: Urea, Polifoska 6, Super Fos Dar 40, enriched with beneficial strains of fungi and bacteria, on selected groups of soil microorganisms was evaluated. The fungi Asper- gillus niger and Purpureocillium lilacinum and bacteria Bacillus sp., Bacillus amyloliquefaciens, Paenibacillus polymyxa, which have been shown to have beneficial effects on plant growth in previous works, have been used as additives to bio-fertilizers. The use of mineral fertilizers Urea, Polifoska 6 and Super Fos Dar 40, enriched with selected strains of fungi and bacteria had a beneficial effect on the development of microorganisms in the rhizosphere of the Thuja occidentalis, especially in the second year of research.

Thuja ocidentalis Smaragd

Opis:
The negative effects of the urban environment on the morphological and physiological states of Thuja occidentalis 'Smaragd' have been investigated. For comparison, two plots were selected for the cultivation of eastern arborvitae cultivars: one in a public garden (the control plot) and the other one in street planting with its positive vertical temperature gradient associated with overheating and dehydration of the soil. This situation had a negative impact on the biometric and physiological parameters of the plants, and, in the end, the level of their vitality. If, under optimal growth conditions, the vertical temperature gradient is negative (the air temperature in the crown is higher and the soil temperature in the rhizosphere zone is lower), the physiological processes in Thuja ocidentalis 'Smaragd' (transpiration, water-holding capacity) proceed in a normal mode. A change in the temperature regime (soil temperature is higher than the air temperature in the crown), under the conditions of a positive temperature gradient, leads to negative consequences: the morphological structure of plants changes (the growth of the apical and side shoots slows down, the number of needles increases, the lower parts of the trunks become bared, the length and volume of the crown are reduced), also physiological processes are disturbed – moisture deficiency increases, water holding capacity decreases, the pigment composition of needles changes towards decreasing the amount of chlorophylls (a + b) and carotenoids. A decrease in the vitality level of the study plants with a positive temperature gradient was confirmed by the vitality indices Rfd established by means of the fluorescence method (negative gradient 0.64; positive gradient 0.33).

Opis:
The market value of essential oils is steadily increasing every year. They are mainly used as aromas and preservatives in food and cosmetics industries. The content and yield of the obtained extracts change across the seasons of the year. The knowledge of these differences is important for essential oils industry to gain the best quality and quantity of products. In this study Thuja occidentalis L. (Eng. northern white cedar) extract was obtained from leaves by maceration in dichloromethane. Plant material was collected during each season of the year and the finished products were thoroughly examined through GC-MS analysis. The seasonal variations of volatile compound composition showed that the most adequate period to obtain T. occidentalis extract on an industrial scale is spring. This is due to the best efficiency (almost 10%) and the highest content of monoterpenes (67%).

Opis:
Thuja occidentalis and T. plicata belong to alien trees most frequently cultivated in Europe. Morphologically they differ significantly from each other and their natural ranges are geographically isolated, hence the taxonomic status of both taxa has never been questioned. In cultivation, however, these species are often very difficult to distinguish so speculations appeared that they can hybridize with each other. Reports about their hybrids growing in the Kórnik Arboretum, Poland, have been delivered several times; for the first time in 1933, then in 1957 and in 1981. In the latter publication, based on those hybrids, a new nothospecies Thuja ×plicatoides was described. That name, however, was not validly published, because its Latin diagnosis was limited only to a few words and no mention was made of how the hybrid differed from its parental species. The analysis of numerous arborvitae specimens growing in the Kórnik Arboretum, and in many other places in Poland, has shown that the earlier reports about the occurrence of Thuja hybrids in cultivation were fully justified. The results of this study were documented by numerous photographs showing the main diagnostic features of T. occidentalis, T. plicata and their hybrids. Special attention was paid to the characteristics of cones, which are rarely used in the Thuja taxonomy. The shape of cone scales, the length of the scale mucro and the structure of small 'lips' on the scale apices turned out to be significant cone features; the latter was used for the first time when distinguishing between both Thuja species. The cone and leaf features made it possible to recognize not only 'pure' species, but also their hybrids. The name Thuja ×plicatoides Seneta, for formal reasons has been rejected, so for the hybrids a new name Thuja ×senetiana has been proposed, which commemorates Włodzimierz Seneta, an outstanding Polish dendrologist.

Opis:
Thuja ×soeegaardii, a hybrid of Th. plicata Donn ex D.Don and Th. standishii (Gordon) Carrière, is described as a new nothospecies from the Kórnik Arboretum, Poland, based on plants obtained in 1988 from the Botanical Garden in Gothenburg, Sweden. The hybrid was found for the first time at the Hørsholm Arboretum, Denmark, in 1938, among seedlings grown from seeds collected from Thuja standishii. Plants grown from rooted scions of this hybrid were planted in several places within the Hørsholm Arboretum. Soon, the hybrid plants were gifted to the Botanical Gardens in Copenhagen and Gothenburg as well to the Poulsen’s Plant Nursery in Kvistgård. In 1967 seedlings were sent from Kvistgård to the National Arboretum in Washington, where one of them developed into a particularly showy, lush and vigorous plant characterized by a dense, narrow, conical crown. The offspring obtained from rooted scions turned out to be very drought and wind-resistant, especially suitable for the formation of tall hedges and windbreak screens. This plant, now very widespread in cultivation, especially in the United States, goes by the name of Thuja ‘Green Giant’. In terms of morphology, many features of Th. ×soeegaardii are intermediate as compared to the parent species. From the Th. plicata, it differs by the following characteristics: leaves not or only weakly shining above, lateral leaves with inwardly curved (not straight) apices, the apical part of lower central leaves thickened and slightly bent from the stem (not appressed), glands on central leaves only weakly visible, central leaves of primary shoots acuminate (not long acuminate) and seed wings sparsely papillose in the upper part (only rarely smooth). From Th. standishii, it can be distinguished by the less glaucous upper leaf surface, the less protruding apical part of lower central leaves, at least faintly visible glands on central leaves, acuminate (not acute) central leaves of primary shoots and less distinctly papillose upper part of seed wings.

Opis:
Nowadays, substances stimulating the growth and development of different agricultural plant species are used in intensive farming. Some of such plant growth regulators are Asahi SL and Moddus 250-EC. So far the literature dealing with growth regulators has focused mainly on their effects on deciduous trees. Because no data are available on how those substances affect conifer trees, this paper presents description of experiments on the effects of Asahi SL and Moddus 250-EC on the increase of tree height and branch length of Picea pungens and Thuja occidentalis. The research has proved that morphological features of the plants tested in the experiment varied according to which growth regulator was used and in what month the measurements were taken. Conifer trees sprayed with Asahi SL had a bigger yearly height growth rate and bigger growth of branches than those sprayed with the stimulator Moddus 250-EC.

W pracy przedstawiono wyniki badań uprawy żywotnika zachodniego odmiany ‘Smaragd’ na podłożach z różnym udziałem keramzytu oraz podłożach szczepionych mykoryzą. Udział keramzytu w poszczególnych próbach badawczych wynosił: 0, 10, 20, 30, 40 i 50%. Przygotowanie próbek do badań polegało na wcześniejszym wymieszaniu gleby z keramzytem i nasadzeniu roślin do wazonów. Badano takie parametry roślin, jak wysokość, masę świeżej części naziemnej (biomasa) oraz masę części podziemnej (korzeni po opłukaniu). Badanie przeprowadzono w okresie 2 lat. Stwierdzono, że największy przyrost roślin można osiągnąć, stosując dodatek keramzytu na poziomie 20–30%. Zaobserwowano również, że zwiększenie przyrostu roślin jest możliwe przy uprawie roślin w kombinacji keramzytu z dodatkiem mykoryzy. Spostrzeżono, że możliwość stosowania dużego udziału dodatku keramzytu w mieszankach podłoży, w połączeniu z jego niewielkim ciężarem, otwiera nowe możliwości wykorzystania tego surowca do upraw roślin na dachach zielonych, garażach podziemnych oraz w budownictwie halowym.
The results of the research growing northern white-cedar (Thuja occidentalis L.) on substrates with different share of expanded clay and substrates vaccinated mycorrhiza. The addition of expanded clay in the individual test samples was: 0, 10, 20, 30, 40 and 50%. Preparation of samples for investigation consist of early mixing of soil with expanded clay and planting of plants for pot. The study was conducted in two years were tested parameters such as growth of plants, the mass of the ground part and the root mass. It was found that the highest growth of plants can be achieved by applying the addition of expanded clay at 20–30%. It was also observed that increasing the growth of plants is possible with the plant cultivation in combination with the addition of expanded clay mycorrhiza. It was noticed that the ability to use a large share of addition of expanded clay in mixtures of substrates, combined with its low weight opens up new possibilities for using this resource for plants in crops for green roofs, underground garages and building a hall.

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:
Gross margin is the difference between the annual value of production from 1 ha of crops and the variable costs incurred in their production. One of the points of this study was t o record individual variable costs for hardy nursery stock, especially consumption and labour costs. It should be mentioned that the gross margin includes just the main variable costs. It is often very difficult to split the other smaller variable costs, e specially between the crop categories. The gross margin evaluated for hedge cultivars of Eastern arborvitae plants grown in containers varied with the area of the nursery, from 95,75 PLN/ha in small nurseries to 125,687 PLN/ha in big ones. For plants grown in the field, the margin was much lower, from 47,217 PLN/ha to 65,527 PLN, respectively.

Opis:
Introduction: Fungal disseases are the most common opportunistic infection. Objective: The main aims of the study were to determine phenolic content and to evaluate the antioxidant and anti-candida activity of the selected Indian-origin plant extracts from the fruit pulp, stem, leaves, and seeds of three plants of Indian origin. Material and methods: The extracts from Terminalia chebula, Thuja occidentalic and Syzygium jambolanum were investigated. The total phenolic content, antioxidant potential of different crude extracts was accessed using the free radical, 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS). Anti-candida activity was evaluated using disk diffusion method and broth dilution assay against Candida albicans. Results: Ethanol and methanol extracts of Indian traditional plants possessed high radical scavenging activity: T. chebula 29.38±0.15, T. occidentalis 6.26±0.24 and S. jambolanum 25.64±0.18 at 0.32 mg/ml. The extracts exhibited good zones of inhibition diameters ranged between: for T. chebula 6.33±0.57 mm and 19.66±1.52 mm in diameter, S. jambolanum 7.00±00 mm and 23.33±1.52 and T. occidentalis 7.66±0.57 and 17.00±1.00 mm. C. albicans were susceptible to all three tested extract at different concentrations. The lowest MIC 1.95 mg/ml was recorded with S. jambolanum while the T. chebula and T. occidentalis inhibited the growth at 3.90 mg/ml, respectively, against the C. albicans. Conclusion: The study result paves an overall view on the bioactivities of three traditional Indian medicinal plants crude extracts.

Opis:
The effect of light conditions on the accumulation of phenolic compounds was investigated in the needles of one-year and two-year old shoots, collected from perennial specimens of common yew (Taxus baccata L.), American arborvitae (Thuja occidentalis L.) and common juniper (Juniperus communis L.), growing in an urban garden. The content of total phenols and flavones was partially related to the light requirement or light tolerance of conifer tree. In Taxus needles, a shade-loving species, higher accumulation of phenolic metabolites was observed under shaded condition (in two-year old shoots) and was linked with the growth intensity in spring. In Thuja and particularly in Juniperus, the level of phenolics was related to the insolation intensity, probably so as a part of the adaptation mechanism.

Opis:
The history of research on tree species of alien origin began in Germany at the beginning of the nineteenth century, when chancellor Bismarck inspired by information about John Booth – who introduced Douglas fir into Europe – became closely interested in that subject matter (North American trees species were characterised by extraordinary productivity). On 15th June 1880, Bernhard Danckelmann – director of the Forest Academy in Eberswalde – was instructed to work out a detailed scheme of the whole system of forest experimental plots. Adam Schwappach was recruited to Eberswalde in 1886 by Bernhard Danckelmann and was to manage the project. Thanks to that, the forest research institute in Eberswalde has today a one of a kind system of permanent experimental plots including 32 species of alien trees originating mainly from North America (26 species), but also from the Caucasus (1), the Balkans (1) and the Japanese archipelago (4). This paper describes the main objects of research on selected alien species (Pseudotsuga menziesii, Thuja plicata, Chamæcyparis lawsoniana, Chamæcyparis pisifera, Tsuga heterophylla) at the Eberswalde Institute and discusses their most significant results from the point of view of a silviculture-expert. One element of particular importance within this analysis is the comparison of productivity of the researched species in relation to yield tables for Scots pine. Experiments concerning the productivity and usefulness of important tree species of alien origin for different scenarios of climate change (dangerous for the natural environment of Central Europe), have been conducted for over 130 years and the results of those experiments are a further subject of this paper.

Opis:
Paper analyses relationships between radial growth and seven crown−related parameters (crown length, relative length, width, slenderness, projection area and volume as well as single tree space) for ten alien and native tree species growing in 'common garden' conditions in the WULS−SGGW Forest Experimental Station in Rogów (central Poland). Significant correlation was found between 10− and 15−years mean tree−ring width and all analysed crown parameters as well as single tree space for Abies grandis, Abies nordmanniana and, except for crown length and its relative length, for Pinus sylvestris. No relationship was observed between radial increment of Larix decidua, Pseudotsuga menziesii and Quercus rubra and any of analysed crown parameters.
