Résumé :
The aim of this study was to investigate the chemical diversity of Pinus nigra Arn. essential oils. The research was carried out on the needles collected from eighteen provenances of black pine grown in common garden located in West-Northern Tunisia and belonging to four different subspecies (Pinus nigra subsp. nigra, Pinus nigra subsp. salzmannii, Pinus nigra subsp. pallasiana, and Pinus nigra subsp. laricio). Essential oil yields ranged from 0.19% to 0.68%. The obtained essential oils have been analyzed by GC-FID and GC-MS apparatus. Twenty-three constituents accounting about 98% of total essential oil composition were identified. The essential oil compositions appeared to be very different according to their origin. Thus, five main essential oil chemotypes were identified in Pinus nigra plants: caryophyllene oxide, camphene, ß-caryophyllene, α-amorphene, and germacrene D. The chemotaxonomic value of the essential oil compositions was discussed in relation to the results of the multivariate statistical test, including a detailed survey of the available literature data.

Résumé :
Досліджено таксономічний склад та проведено географічний аналіз P. nigra у вуличних насадженнях Умані. На підставі відповідності віковим параметрам діаметра та висоти її окремих екземплярів, відзначено високу стійкість рослин до складних умов урбанізованого середовища та встановлено перспективність використання виду, за дії на нього чисельних антропогенних факторів. Результати показують, що всі досліджувані рослини P. nigra мають високі показники життєздатності та належать до першої групи перспективності. Значення акліматизаційних чисел свідчать про перспективність інтродукції P. nigra та успішність акліматизації в умовах урбанізованого середовища. Оцінивши декоративні якості P. nigra, виявлено, що в основному вона виділяється на фоні інших видів своєю компактною овальною чи конусоподібною кроною, темно-сірою з різними відтінками тріщинуватою корою та довгою темно-зеленою хвоєю. Саме завдяки цим якостям вона зберігає привабливий вигляд протягом усього року, навіть у зимовий період. На підставі отриманих результатів, сумарний річний показник декоративності основних ознак P. nigra становить 4 бали і свідчить про наявність високих декоративних якостей рослин цього виду. Отже, використання P. nigra в урбанізованому середовищі покращує екологічні умови міста та позитивно впливає на емоційний стан населення.

Résumé :
UDK 630*232:582.475 U istraživanju je korišteno sjeme crnog bora podrijetlom iz klonske sjemenske plantaže “Prkos” (nije priznata), Uprave šuma Podružnica Gospić, Šumarija Gospić (urod 2001), dorađeno tijekom zime 2001/2002 u trušnici u Šumarskom institutu Jastrebarsko. Prilikom sjetve u sjemeništu rasadnika, bitna je količina sadnica po jedinici površine (ovisno o vremenu zadržavanja u sjemeništu 1, 2, ili 3 godine), što ovisi o kakvoći sjemena (punoća, čistoća, klijavost i dr.), te o količini posijanog sjemena (kom / m2 ili g / m2) koja je određena formulom na osnovi koje dobivamo potrebnu količinu sjemena za željeni broj biljaka. Za gustoću sjetve, u dosadašnjoj praksi uglavnom su se koristile neke iskustvene norme i načini izračunavanja broja odnosno količine sjemena po m2. U našim istraživanjima razvidno je kako smo dorađenim sjemenom (do 98% punoće) i manjim brojem sjemenki dobili veći broj biljaka u odnosu na broj istih dobivenih iz manje kvalitetno dorađenog sjemena. Isto tako, razvidno je kako pri sjetvi na osnovu formule “1” (X = broj sjemenki / m2) dobivamo od 40% do 45% željenog broja biljaka, dok sijanjem količine sjemena po formuli “2” (N = količina sjemena u g / m2), dobivamo 3,5 puta više biljaka crnog bora od željenog broja (željeni br. “V”). Određenim izmjenama postojećih formula za izračunavanje potrebne količine sjemena za željeni broj biljaka, postigli bismo veću točnost, što je i potvrđeno u ovim istraživanjima sa sjemenom crnog bora. Ista istraživanja (sa sjemenom – jele i bukve), provodimo u drugim rasadnicima, gdje preliminarni rezultati ukazuju na sličnost s prikazanima u ovome radu, čime bismo potvrdili navedeno.

Résumé :
During a study on the live crown characteristics of Pinus laricio (Pinus nigra Arn. ssp. laricio (Poir.) Maire), the observation of branch cross-sections allowed us to work on the problem of the discontinuance of cambial activity. This work points out the existence of missing rings with a histologic point of view and establishes the generality of the phenomenon for this species. In addition to the observations at the base of living branches, the cross-sections in all the successive growth units of the branch were observed to establish the distribution of the annual wood layers along the branch and to ascertain the dissymmetry between the upper side and the lower side of the branch. The occurrence of this phenomenon in the upper part of the crown raises the problem of the contribution of these branches to tree development and its implication in forest management.Key words: growth rings, Pinus nigra Arn. ssp. laricio (Poir.) Maire, missing rings, anatomy, branch growth, crown.

Résumé :
The present paper aims to investigate the chemical composition of unripe black pine seeds obtained from Bulgaria. The lipid fraction was evaluated in unripe seeds, and the cellulose, total carbohydrates, glucose, fructose, and sucrose were evaluated in seedcakes. The major fatty acid identified in the Pinus nigra seed oil was unsaturated linoleic acid (44.2%), followed by the saturated palmitic acid (31.2%). The amount of unsaturated pinolenic (10.5%) and oleic acids (8.8%) was also rather high. The amino acid composition of the protein fraction of seedcakes was also determined. The amino acid composition was represented mainly by asparagine (3.92 mg/g), serine (3.79 mg/g), alanine (3.65 mg/g), arginine (3.32 mg/g), phenylalanine (2.98 mg/g), lysine (2.85 mg/g), proline (2.69 g/mg), tryptophan (2.44 mg/g), valine (2.33 mg/g), isoleucine (2.28 mg/g), and tyrosine (2.05 mg/g). The mineral content (N, P, K, Mg, Na, and Cu) of the seedcakes was evaluated, as the amount of K (8048.00 mg/kg) and Mg (172.99 mg/kg) were the highest in the samples. These findings emphasized the potential use of the unripe black pine seeds in different areas due to their chemical importance and values.

Résumé :
The experimental studies were conducted from 2015–2017 years in two cycles. The aim of the research was to determine a better grafting time and a choice of an appropriate rootstock for the propagation of two cultivars of mountain pine (Pinus mugo Turra). The influence of the grafted cultivar and rootstock used on the level of chloroplast pigments in the needles was also checked. The studies concerned two cultivars of mountain pine (Pinus mugo) ‘Grześ’ and ‘Zundert’, which were grafted on four different rootstocks: Pinus contorta (Dougl. ex Loud.), Pinus nigra (Arn.), Pinus sylvestris (L.) and Pinus mugo subsp. uncinata (Ramond Domin) in two dates: 20 January and 15 March. The highest percentage of graft success was obtained for the two cultivars on Pinus uncinata and Pinus contorta rootstocks. A later term of grafting procedure affected bigger effectiveness of grafting of the two studied cultivars, except for the graft success on Pinus sylvestris rootstock. The highest increments of side shoots and lengths of main stems for ‘Grześ’ cultivar were obtained on Pinus nigra, and for ‘Zundert’ the influence of the rootstock on the above mentioned parameters was not evident. No significant differences in the number of increments in the first and second year of studies were observed. The highest level of chlorophyll A and B was found in the needles of ‘Grześ’ cultivar, independently from the rootstock used. Among tested rootstocks, only Pinus nigra had a significant impact on a higher content of chlorophyll B in the needles of the studied cultivars of mountain pine trees.

Résumé :
AbstractGlucanase and chitinase enzymes play an important role in different plant processes including defense against pathogens and morphogenesis. Moreover, their role in the processes of somatic embryogenesis has been demonstrated. It has been suggested, that the presence of this type of proteins might be a marker for embryogenic potential of callus cultures. In this work we screened for the presence of glucanases and chitinases in liquid growth media of a set of conifer embryogenic cell lines in order to find correlation with their embryogenic potential. We have found that none of the 12 chitinase isoforms detected in culture media of Pinus nigra Arn. or the nine chitinases detected in media with Abies alba × A. cephalonica and Abies alba × A. numidica embryogenic tissues could be linked to their embryogenic capacity. Similarly, none of the six glucanase isoforms detected in the extracellular fluid of Pinus nigra Arn. cultures can be assigned as a marker of embryogenic potential. Thus, our data indicate the large variability and doubtless importance of glucanases and chitinases for cell growth and development of somatic embryos, however, do not support the premise that they are markers of embryogenesis.

This paper presents the results of studies on protein polymorphism in seeds of Scots pine (Pinus sylvestris L.) and Austrian pine (Pinus nigra Arn.) as the most important economic species of the genus Pinus in Serbia. Polymorphism of protein markers was determined in selected genotypes originating from seven populations (Scots pine) and six populations (Austrian pine). Analysis of protein markers was performed using two statistical methods, NTSYS and correspondence analysis. Both methods give the same arrangement of the analyzed populations, whereby, because of a different view of genetic distances, they can and should be combined, enabling easier and more precise understanding of mutual relationships of the observation units.

Résumé :
Total height is one of the basic morphometric tree variables included in all forest management inventories, because it is connected with several forest processes and functions related to the estimation of the woody tree volume and sustainable forest yield. The current research, based on a total sample of 1059 measured Black pine (Pinus nigra Arn.) trees from Cyprus, is an attempt to explore the biological processes related to the tree height allometry of this species and develop a generalized mixed-effects model for tree height prediction. The proposed model, with three additional basic covariates and two random parameters, explained almost 96% of the height variance. The model results showed that although competition and site-connected variables affected the total height, it was the crown base height that explained, to a large degree, the height expression. Through the mixed-effects modeling approach it was possible to explore the complex biological processes related to the tree allometry of Black pine and depict those within a mathematical formulation. The proposed generalized model decreased the error significantly, and therefore it can be used for operational forest management purposes. However, for marginal predictions, use of only the fixed part of the basic model could suffice, since this also provided unbiased parameter estimates.

Résumé :
Seed orchards are an important source of seeds with improved genetic quality. Here we present results of a study on the genetic composition of seed orchards crop of Austrian black pine (Pinus nigra Arn.). Two seed orchards were included in the study – a clonal seed orchard established near Sliven, and a seedling seed orchard, established in the region of Simitli. The outcrossing rates were higher in the clonal seed orchard (Sliven), 0.873 and 0.806 multi-locus (tm) and single-locus (ts) estimates, respectively. The same values were 0.623 and 0.530, respectively, in the seedling seed orchard (Simitli). The inbreeding coefficient was positive in both cases, but was significantly different from zero in the clonal seed orchard only (0.101 vs. 0.032). Thus, the two studied seed orchards demonstrate different genetic efficiency. The results are discussed in relation to seed orchard management and efficiency.

Résumé :
This paper presents the results of soil research in Austrian pine (Pinus nigra Arn.) forest communities in the Visegrad area, carried out to determine the basic soil characteristics and eco-production potential of forest habitats as an important basis and framework for the successful management of these forests on the principles of sustainable development. Austrian pine forests in this region are an important and ecologically valuable community. The complexity of the geological structure and relief dynamics are dominant environmental factors that condition the expressed variability of soils in the study area. Forest communities of Austrian pine are formed on the peridotites and serpentinites, eutric ranker (haplic leptosol), eutric cambisol (haplic cambisols) and pseudogley (haplic planosol), dense granular and marl limestones calcomelanosol (mollic leptosol), rendzina (rendzic leptosol) and calcocambisol (leptic cambisol). The productivity of these soils is highly correlated with depth and texture composition, and the impact of these factors is linked with soil type, climate and other site conditions. In the research area, soil types with low production potential such as rankers, rendzinas, limestone and dolomite calcomelanosol are dominant. Deeper variants of eutric cambisol, pseudogley and calcocambisol can be classified as soils with moderate to high production potential.

Résumé :
A high-throughput quantitative Nuclear Magnetic Resonance 1H-NMR method was developed and applied to screen the quantity of the diterpenic resin acids in the heartwood of black pine, due to the renewed scientific interest in their medicinal properties and use in various diseases treatment. The 260 samples were taken from Pinus nigra clones, selected from four provenances of the Peloponnese (Greece), participating in a 35-year-old clonal seed orchard. Total resin acids per dry heartwood weight (dhw) varied greatly, ranging from 30.05 to 424.70 mg/gdhw (average 219.98 mg/gdhw). Abietic was the predominant acid (76.77 mg/gdhw), followed by palustric acid (47.94 mg/gdhw), neoabietic acid (39.34 mg/gdhw), and pimaric acid (22.54 mg/gdhw). Dehydroabietic acid was at moderate levels (11.69 mg/gdhw), while levopimaric, isopimaric, and sandaracopimaric acids were in lower concentrations. The resin acid fraction accounted for 72.33% of the total acetone extractives. Stilbenes were presented in significant quantities (19.70%). The resin acid content was composed mainly of the abietane type resin acids (83.56%). Peloponnesian Pinus nigra heartwood was found to be the richest source of resin acids identified to date and is considered the best natural source for the production of such bioactive extracts. The results indicate a high potential for effective selection and advanced breeding of pharmaceutical and high economic value bioactive substances from Pinus nigra clones.

Texte intégral
Résumé :
Wildfires are currently considered the major threat to forests in Mediterranean countries. It has been implied that a large percentage of arson-caused fires in Spain are connected with the extensive reforestation programs implemented between 1940 and 1970. However, no consistent studies have been conducted to study the relationships between arson-caused fires and stand origin. Therefore, the goal of this study was to analyze occurrences and model the influence of forest stand origin (artificial or not) on the development of wildfires in peninsular Spain. Twenty-one neural network models were trained to estimate fire incidence through fire type (surface or crown fire), burned area and total treed burned area, based on stand age (years), canopy cover (%), natural age class (from seedling to mature stages) and fuel type classification. Models were built for reforested stands and natural stands of Pinus pinaster Ait., the Mediterranean pines Pinus sylvestris L., Pinus nigra Arn., Pinus halepensis Mill. and Eucalyptus sp. L’Hér., or groups of these species, and the resulting models were compared. Reforested stands presented higher fire incidence than natural stands mainly for productive species like Pinus pinaster Ait. According to the fire type models, thickets had a large influence in the development of crown fires in reforested stands in a general model for all species, the model with the Mediterranean group of pines, and the Pinus pinaster Ait. model. Vertical continuity influenced crown fire propagation in natural Mediterranean pines and in Eucalyptus stands. Presence of shrubs, grasslands and wood slash was related to surface fires in models for both reforested and natural stands. The results suggested that stand origin was influential on fire incidence, at least with regard to fire type and commercial species in the northwestern region of Spain.

Résumé :
The aim of the present study was to determine the thermodynamic and kinetic parameters of biomass obtained from black pine (Pinus nigra Arn.). The biomass, consisting of twigs with needles and needles alone of black pine, was used. Ultimate analysis with the elemental composition of the biomass with respect to the main components such as carbon (C), hydrogen (H), nitrogen (N), and sulfur (S) of the biomass before and after water distillation was made. The high heating value (HHV) and low heating value (LHV), energy density and fuel value index were determined. Thermodynamic (Gibbs energy, enthalpy, and entropy) and kinetic (activation energy, the rate constant of the process, and reaction order) parameters of the biomass were calculated.

Résumé :
This paper discusses research results concerning properties of substrates used for nursery production of Austrian pine (Pinus nigra Arn) and Scots pine (Pinus silvestris L) in the experimental field of the Faculty of Forestry in Belgrade There is no doubt that peat is the most favorable substrate for successful massive nursery production of various woody species. Favorable physical, chemical and biochemical properties guarantee nursery production success, on condition that all technical and technological procedures, characteristic for this production, are recognized. Certain shortcomings that may occur with different kinds of peat (inadequate air capacity, nutrient deficiency, excessive acidity, etc) may relatively easily be overcome with appropriate materials and procedures. Nevertheless, the main shortcoming of this most widely used nursery substrate, especially when the countries with economies in transition are concerned, is its high price. In order to overcome this problem, it is necessary to use domestic resources for creating a substrate of approximately the same characteristics, but much lower price Research results regarding the substrate ? mixture "Goc 1" show that this substrate, comprising 30% silica sand, 20% earthworm manure, and 50% bark humus, is characterised by all necessary starting prerequisites for fulfilling the cited functions. This material represents loamy sand of almost neutral reaction (pHH2O=6.9, pHCaCl2=6.40), and even though its CEC is relatively modest (33.08 cmol(+) x kg?1), it is extremely well supplied with bases (V=94.32%). Also, "Goc 1" is rich in humus (8.94%), with relatively high content of total N (0.47%), and favorable C:N ratio (11.0). It is extremely well supplied with available phosphorus and potassium (>50 cmol(+) x kg?1). Further research regarding stability of this artificial substrate and alterations of its physical, chemical, and biochemical properties in the course of exploitation, together with monitoring the growth and development of Austrian and Scots pine seedlings, will show if the composed mixture "Goc 1" is of good enough quality to successfully replace peat in massive nursery production of Pinus nigra Arn., and Pinus silvestris L. in the future.

Résumé :
M. pini is one the most widespread and dangerous pathogenic fungi in the plantations of Pinus species in the world. This fungus has been observed on more than fifty Pinus species, and on European Larch, Douglas Fir, Norway Spruce, Serbian Spruce and Sitka Spruce. In Serbia, M. pini caused greatest damage in plantations of Austrian pine (P. nigra Arn). In Serbia both states of the fungus have been observed, i.e. conidiomata and ascostromata. Conidia are far more significant in the infection process. The critical period for infections is May - June. Of the all tested fungicides, the best results have been obtained by copper protectants. In heavily infected plantations of Austrian pine the protections should be carried out in the period when the plantations are 5-20(25) years old.

Résumé :
We have developed a method for the routine isolation of Pinus nigra Arn. ssp. salzmannii (Dunal) Franco protoplasts. The optimized electroporation conditions for uidA gene (gene for beta-glucuronidase) expression in protoplasts from cotyledons excised from 8-day-old seedlings were determined using an exponential pulse wave generator for gene transfer. The protoplasts were electroporated with plasmids containing the chimeric uidA gene under the control of several promoters, and in parallel, cotyledons were bombarded with the same constructs using a biolistic gun. Both techniques confirmed that gene expression was higher when controlled by the sunflower polyubiquitin gene promoter than by the cauliflower mosaic virus CaMV35S promoter, whereas the rice actin and maize alcohol dehydrogenase promoters resulted in lower uidA expression levels, as determined fluorometrically. In this study, the electroporation procedure has been more effective than the particle bombardment procedure to determine the promoter strength on transient gene expression in P. nigra.

Résumé :
Aleppo pine (Pinus halepensis Mill.) is the most widely disturbed conifer tree in native forest and plantations throughout the Adriatic coast of Montenegro. However, pathogenic fungi in the region are extremely diversified and constitute the principal threat to healthy tree growth: 15 pathogenic fungal species have beden identified in the Eumediterranean zone - a typical habitat of Aleppo pine, whereas 21 fungal pathogens occurred in northern Submediterranean zone - an atypical habitat for Aleppo pine in Montenegro. Greatest damages are inflicted by Sphaeropsis sapinea, a pathogenic generalist on pine, and Cronartium flaccidum, causal agent of rust disease on pine. The following relates, for the first time, the presence of hypersensitive response (HR) in young needles and shoots (organs rich in nitrogen) as a specific defense mechanism in Aleppo pine against Sphaeropsis sapinea, an otherwise very harmful pathogen for Austrian pine (Pinus nigra Arn.) and other pines in the Mediterranean part of Montenegro. Thus, better understanding of the ecology of S. sapinea, of C. flaccidum, as well as of associated mycobiota and mechanisms of host defense are essential for establishing measures and tools for protection of Aleppo pine ecosystems.

Texte intégral
Résumé :
The invasive potential of the nonnative Austrian black pine (Pinus nigra subsp. nigra Arn.) was analyzed in a 100-year-old Mediterranean mixed deciduous forest in the Massane Nature Reserve, eastern Pyrenees (France). The reserve holds approximately 120–150 semiferal cattle (Bos taurus L.) that browse and trample the woody regeneration. Tree age structure was assessed by dendrochronology to reconstruct the pine population dynamics in grazed and nongrazed (fenced in 1954) portions of the forested reserve. The age structure of the pine population regenerating before 1960 was similar between the inside and outside of the enclosed reserve area. Since 1960, pine recruitment has occurred only in the nongrazed area. The diameter variability with age changed since the 19th century. For pines less than 20 years old, the diameter variability is low, whereas it is very high for individuals older than 100 years. Diverse forest structural changes (composition, canopy height, density, etc.) likely explain the variability in diameter at a given age. Cattle do not appear to affect tree growth as it is similar inside and outside the fenced area, but they control the regeneration of nonnative Austrian black pines, which can spread in the absence of cattle. If nonnative black pine poses a risk for forest conservation, large herbivores may play a useful role in maintaining this species at low abundance.

UDK 630*5:582.4(497.6) Dugo prisutan problem u šumarstvu BiH je velika zastupljenost slabo produktivnih, uglavnom nekvalitetnih izdanačkih šuma ili neobraslih površina. Na oko 50% šumskih površina u BiH proizvodni potencijal staništa ne koristi se optimalno, odnosno ne proizvodi se maksimalna količina kvalitetnog drveta. Jedna od primjenjivanih mjera za prevazilaženje ovog problema je unošenje i podizanje zasada autohtonih i alohtonih vrsta drveća koje se odlikuju brzim rastom i kvalitetnim drvetom. Podignuti su brojni zasadi smrče (Picea abies Karst.), bijelog (Pinus sylvestris L.) i crnog bora (Pinus nigra Arn.), te u manjem broju zelene duglazije (Pseudotsuga mensiesii Franco.), evropskog (Larix europaea L.) i japanskog ariša (Larix leptolepis Gord.) i američkog borovca (Pinus strobus L.). Postignuti rezultati su zbog nedostatka iskustva bili različiti. Provedena su istraživanja proizvodnih i strukturnih karakteristika zasada smrče, bijelog i crnog bora u BiH, dok su za alohtone vrste drveća istraživanja provedena samo parcijalno. Prilog tom istraživanju je i istraživanje predstavljeno u ovom radu. Cilj ovog rada je analiza i ocjena proizvodnosti šest vrsta četinara (3 autohtone i 3 alohtone) u komparativnom ogledu na području Gostovićke rijeke.

Résumé :
The increased frequency and intensity of warming-induced droughts have triggered dieback episodes affecting many forest types and tree species worldwide. Tree plantations are not exempt as they can be more vulnerable to drought than natural forests because of their lower structural and genetic diversity. Therefore, disentangling the physiological mechanisms leading to growth decline and tree mortality can provide tools to adapt forest management to climate change. In this study, we investigated a Pinus nigra Arn. plantation situated in northern Spain, in which some trees showed canopy dieback and radial-growth decline. We analyzed how radial growth and its responses to drought events differed between non-declining (ND) and declining (D) trees showing low and high canopy defoliation, respectively, in combination with carbon (δ13C) and oxygen (δ18O) isotope ratios in tree rings. The radial growth of P. nigra was constrained by water availability during the growing season and the previous autumn. The radial growth of D trees showed higher sensitivity to drought than ND trees. This fact is in accordance with the lower drought resilience and negative growth trends observed in D trees. Both tree classes differed in their growth from 2012 onwards, with D trees showing a reduced growth compared to ND trees. The positive δ13C-δ18O relationship together with the uncoupling between growth and intrinsic water-use efficiency suggest that D trees have less tight stomatal regulation than ND trees, which could involve a high risk of xylem embolism in the former class. Our results suggest that different water use strategies between coexisting ND and D trees were behind the differences in growth patterns and point to hydraulic failure as a possible mechanism triggering dieback and growth decline.
