AB  - Landmark-based geometric morphometrics (GM) was used to examine, for the first time, spontaneous hybridization between Alnus incana (L.) Moench and Alnus rohlenae Vít, Douda and Mandák, and to assess inter- and intrapopulation variability in leaf shape, leaf size and venation in natural populations in Serbia (Western Balkans). Two geographically distant (30 km) and two close (1.2 km) populations were selected to examine hybridization. The variability in leaf shapes was assessed by canonical variate analysis and linear discriminant analysis performed on the symmetric component of variation. Covariation between the symmetric component of shape variation and the number of pairs of secondary leaf veins was investigated with partial least squares analysis. Static allometry was examined for the first time in the genus Alnus Mill. A higher proportion of A. incana leaves was classified as A. rohlenae in geographically close populations, which is in accordance with the hypothesis about spontaneous hybridization. No single leaf of A. rohlenae was classified as A. incana, indicating that putative hybrids can only be found in grey alder populations. This study demonstrates that GM is a powerful tool for species delimitation and hybrid detection in the genus Alnus and it can be used for preliminary screening in hybrid zones.

AB  - Phytochemical profiling of six natural populations of Gentianella austriaca was performed
by HPLC identification and quantification of a number of secondary metabolites, and evaluation of time series of peak areas by chemometric analysis. Phytochemical analysis of G. austriaca revealed the presence of iridoids, flavone-C-glucosides and xanthones. Twelve secondary metabolites were identified in the aerial parts, roots and seeds, including swertiamarin (SWM), gentiopicrin (GP), sweroside (SWZ), isoorientin (ISOOR), swertisin (SWE), demethylbellidifolin-8-O-glucoside (DMB-8-O-glc), bellidifolin-8-O-glucoside (BDF-8-O-glc), mangiferin (MGF), corymbiferin (CBF), corymbiferin-1-O-glucoside (CBF-1-O-glc), bellidifolin (BDF) and campestroside. Multivariate statistical analyses showed relatively low variability among populations according to secondary metabolite content. However, some pharmacologically important compounds were found in higher amounts in a few populations, which could be useful for conservation and future biotechnological procedures.

AB  - Introduction: A variety of plant traits, from architectural to the cellular level, have been connected to flammability, but intraspecific variability of plant traits (ITV) and components of flammability is poorly studied. The lack of knowledge about ITV of plant traits related to flammability appears to be a major shortcoming in further interpreting species flammability and fire behavior and incorporating the data into models.

Methods: Morpho-ecophysiological traits (width, length, thickness, weight, area, volume, moisture content, flatness, specific leaf area, density of leaf tissue, ratio of area to volume) and time-to-ignition of fresh foliage were measured in seven populations of Picea omorika.

Results: All leaf traits are presented along with their correlations to the flammability trait. The seven populations differed in terms of fresh leaves’ time-to-ignition. Differences among populations in morpho-ecophysiological traits were also significant but not consistent among populations. PCA classified 49 elements into three different groups, where three populations were clustered by higher leaf area-related traits, other three populations were clustered by higher leaf length, volume, thickness, time-to-ignition, density index, moisture content, width, weight, and one population was classified between the two main groups. The first two principal components accounted for 87% of the total variance: variability in leaf area- and leaf weight-derived parameters (specific leaf area and density index) and time-to-ignition primarily defined the formation of the first axis, while variability in leaf flatness (based on leaf weight and thickness) primarily contributed to the formation of the second axis.

Discussion: Results suggest high ITV in natural populations of P. omorika regardless of site fire history.

AB  - Deliblato Sands is the single largest expanse of sand in Europe. It is the most fire-prone area of Serbia due to the absence of surface water, sandy soils, specific microclimate conditions, and vegetation composition. Post-fire regeneration is a long-term process that includes many aspects of vegetation regrowth and habitat recovery. In the third year following one of the disastrous fires, the growth dynamics of two geophyte species in unburned and burned sites were studied. During the growing season, burned and unburned populations of Crocus reticulatus Steven ex Adam and Iris pumila L. were assessed for growth parameters (biomass production, specific leaf area, leaf area index) and leaf-level ecophysiological traits (photosystem II efficiency, chlorophyll amount, relative water content). Species acclimated differently to changed abiotic and biotic site conditions after the fire event. C. reticulatus burned and unburned populations differed significantly in terms of flowering phenology and ecophysiological traits, whereas I. pumila burned and unburned populations differed significantly in terms of growth parameters. The findings support the assertion that geophytes are generally well adapted to environmental disturbances. Species, however, responded differently to fire-induced changes in the physicochemical and biotic environment, depending on their ecological requirements and adaptive capacity.

AB  - Natural populations of Gentiana asclepiadea L., located at two mountainous sites, were HPLC-analyzed regarding the contents of six representative secondary metabolites. The contents of swertiamarin (SWM), gentiopicrin (GP), sweroside (SWZ), mangiferin (MGF), isoorientin (ISOOR), and isovitexin (ISOV) were determined in six populations (three per study site), and separately for aboveground and belowground plant parts. PCA showed a clear separation of four groups according to the contents of the analyzed secondary metabolites. Out of six analyzed compounds, five were present in all samples and only one (SWZ) was found in Golija populations (belowground parts) but not in Vlasina populations, and its presence can be indicative of the geolocation of populations. Clear separation of groups was mostly affected by the different contents of chemical compounds in plant parts (aboveground versus belowground) and by the differences related to population origin (higher content of SWM and GP in belowground parts of individuals from Vlasina populations and higher content of MGF and ISOOR of individuals from Golija populations). The results of this study contribute to the spatiochemical profiling of G. asclepiadea populations and a better understanding of inter- and intrapopulation variability of pharmacologically important compounds.

AB  - Natural populations of Rubus hirtus Waldst. & Kit. were studied at three locations along the Gabrovnica river on Stara Planina mountain, to assess the inter-population differences in ecophysiological and ecomorphological parameters. The content of total chlorophyll in leaves, estimated by the SPAD method, as well as leaf width and leaf width/length ratio had the highest values in population A, which inhabits a forest community dominated by hornbeam and sessile oak and grows in vegetative shade. Populations B (which is also located within the forest complex) and C (which is located in a relatively open habitat) had lower values for the examined parameters. Inter-population differences in the examined parameters can be partially interpreted as an adaptation to habitat light conditions (significant differences between individuals from populations A and C). However, the values of parameters in population B cannot be explained by light conditions, indicating the need to consider complex environmental conditions at that site, primarily heavy metal contamination of soil and groundwater.

Within a species’ area of distribution, a wide range of biotic and abiotic factors synergistically shape different habitats, and plant populations develop a set of specific features to respond to given environmental conditions. Distinct populations with phenotypic differences determine the ecotypes within the taxon. Similarly, the chemotype is defined as a chemically distinct plant population, according to the composition of secondary metabolites. Many secondary metabolites have pronounced biological activities and implications for human health. With respect to searching for new sources of secondary metabolites with potential health effects, natural populations of plant species attract the substantial attention of researchers because their habitats are highly diverse and unpolluted. Many studies on this subject have confirmed the biological and chemical diversity of natural populations and emphasized the need for the conservation of natural resources.

AB  - Wild edible fruits are highly valued in human nutrition and traditional medicine due to their high content of dietary fibers, vitamins, minerals, and natural antioxidants. Physiologically active components that can potentially reduce risks for chronic diseases leads to these plants being classified as “functional food.” The different classes of phytochemicals can be synthetized based on plants’ genetic potential and environmental conditions. Although these phytochemicals have a lower bioactive potential than pharmaceuticals, their daily intake in small amounts can have noticeable long-term physiological effects. The area of the Balkan Peninsula is characterized by a unique biodiversity and represents one of the centers of plant diversity. Serbia is distinguished by its exceptional floral diversity of vascular plants, which is the result of specific climatic, orographic, edaphic, and historical conditions. Wild fruits mostly inhabit mesophilous deciduous forests in hilly–mountainous regions. In the territory of Serbia, over 90 species of wild fruits have been described, belonging to 15 families and 26 genera.

AB  - Variability in the contents of representative secondary metabolites in Gentiana pneumonanthe individuals was investigated in relation to population origin, plant parts and developmental stage. Chemical analyses (HPLC) of six secondary metabolites (swertiamarin (SWM), gentiopicrin (GP), sweroside (SWZ), mangiferin (MGF), isoorientin (ISOOR), and isovitexin (ISOV)) were performed for individuals from six populations located within a 3 × 3 km area at Maljen Mt., and separately for below- and above ground plant parts in three developmental stages. Different plant parts showed pronounced differences in the contents of the six secondary metabolites and a high level of variability during the plant ontogeny. The highest contents of three dominant compounds (SWM, GP, and MGF) were detected in different developmental stages. Both below- and above ground plant parts contained GP, MGF, SWZ, and SWM at some developmental stages, whereas ISOOR and ISOV were registered in above ground parts. The full-flowering stage was characterized by the highest contents of MGF, GP, and ISOOR in aboveground-, and GP in belowground parts. In the post-flowering stage, a high content of MF was detected in below ground parts. The results of this study contribute to a better understanding of interpopulation, ontogenetic and between-organ variability in rare and threatened G. pneumonanthe.

AB  - Helichrysum plicatum DC. is widely used in folk medicine in treating a variety of health disorders. The aim of this study was to examine the influence of different extraction solvents on the chemical composition, antioxidant potential, and antimicrobial activities of H. plicatum. Aerial parts were separately extracted with ethanol, dichloromethane, and sunflower oil. The oil extract (OE) was re-extracted with acetonitrile. A total of 142 compounds were tentatively identified in ethanolic (EE), dichloromethane (DCME), and acetonitrile (ACNE) extracts using HPLC-DAD/ESI-ToF-MS. The dominant compound class in all extracts were α-pyrones, alongside flavonoids in EE, terpenoids in DCME and ACNE, and phloroglucinols in DCME. The antioxidant potential of the extracts was assessed by the 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) assay. EE and DCME possessed the most potent radical scavenging capacity. Antimicrobial activity was investigated on eight bacterial, two yeast, and one fungal species. All extracts exhibited high antifungal and notable antibacterial activities compared to control substances, with DCME being the most potent. DCME exhibited stronger antimicrobial activity against P. aeruginosa than the standard chloramphenicol.

AB  - Inter- and intrapopulation variability in six natural populations of the rare species Gentiana pneumonanthe was examined based on morphological and chemical data. Population size and linear morphometric parameters differed significantly among populations, but without a clear connection to habitat conditions, i. e. water supply and light availability. Leaf shape varied from ovate to lanceolate in all populations, and one population was distinctive in having the largest number of leaves of transitional shape. HPLC analyses of six secondary metabolites were performed separately for belowground parts, and aboveground vegetative and reproductive parts of individual plants (6 populations ×7 individuals ×3 plant parts, n=126) in order to examine differences at the population and individual levels. Three secoiridoids (swertiamarin (SWM), sweroside (SWZ), and gentiopicrin (GP)), one xanthone (mangiferin (MGF)), and two flavones (isoorientin (IO) and isovitexin (IV)) were detected and quantified in the analyzed samples: sweroside dominated in the aboveground reproductive part, mangiferin in the aboveground vegetative part, and gentiopicrin in the belowground part. At the population level, differences in contents of the analyzed chemicals among populations were significant only for a few metabolites. At the individual level, a pronounced organ-dependent distribution of secondary metabolites was revealed. The results of this study contribute to a better understanding of natural variability within populations of the rare and threatened G. pneumonanthe, and provide data on the contents and within-plant distribution of secondary metabolites, which are important as pharmacologically active compounds and may be useful for further biotechnological procedures regarding this species.

AB  - The reliability of diarylheptanoids as chemotaxonomic markers at inter- and intraspecific levels has been investigated. Six diarylheptanoids were quantified in bark ethanol extracts of four Alnus spp. populations by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The populations described here as locus classicus Alnus glutinosa (I) and locus classicus Alnus incana (III) are clearly differentiated. Compared to population I, individuals in population III have higher extract yields and hirsutanonol-5- O - β -D-glucopyranoside content and lower contents of hirsutanonol, rubranoside A and oregonin. Individuals from neighboring populations of A. glutinosa (II) and A. incana (IV) share similar contents of hirsutanonol. All the studied populations exhibit a high intrapopulation variability of the selected diarylheptanoids; they have a heterogeneous chemotype and they partially overlap. The geographical proximity of populations II and IV increases their chemical similarity. Principal component analysis (PCA) clearly shows that the biggest dispersion of individuals lies within population IV. The reason for its heterogeneity might be its physical proximity to population II, i.e. the appearance of hybrids. Also, geometric morphometrics of leaves was performed as a screening criterion for spontaneous hybrids.

AB  - Diarylheptanoids are a group of secondary metabolites widely distributed in the Betulaceae family and characteristic for Alnus species. In this study, the chemotaxonomic power of diarylheptanoids, such as hirsutanonol-5-O-β-d-glucopyranoside, rubranoside A, oregonin, platyphylloside, alnuside A and hirsutanonol, has been investigated in combination with principal component analysis (PCA) for differentiation of Alnus species. Concentrations of six diarylheptanoids in the bark extracts of two natural populations of Alnus glutinosa (black alder) and Alnus incana (gray alder) were determined by ultraperformance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). PCA clearly shows the separation of three groups. Populations I (A. glutinosa) and II (A. incana) both consisted of individuals of the corresponding species. Four individuals from both sampled populations formed a separate group (population III), which possibly represents a hybrid group. Accordingly, diarylheptanoids may serve in combination with PCA as chemotaxonomic markers at the species level, which may also reveal hybrid species.

abstract = "Diarylheptanoids are a group of secondary metabolites widely distributed in the Betulaceae family and characteristic for Alnus species. In this study, the chemotaxonomic power of diarylheptanoids, such as hirsutanonol-5-O-β-d-glucopyranoside, rubranoside A, oregonin, platyphylloside, alnuside A and hirsutanonol, has been investigated in combination with principal component analysis (PCA) for differentiation of Alnus species. Concentrations of six diarylheptanoids in the bark extracts of two natural populations of Alnus glutinosa (black alder) and Alnus incana (gray alder) were determined by ultraperformance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). PCA clearly shows the separation of three groups. Populations I (A. glutinosa) and II (A. incana) both consisted of individuals of the corresponding species. Four individuals from both sampled populations formed a separate group (population III), which possibly represents a hybrid group. Accordingly, diarylheptanoids may serve in combination with PCA as chemotaxonomic markers at the species level, which may also reveal hybrid species.",

AB  - Ovim istraživanjem obuhvaćene su dve populacije Alnus glutinosa (L.) Gaertn. (Prilički kiseljak i Rimski most) i dve populacije Alnus incana (L.) Moench (Golijska reka i Sastavci) uzorkovane na planini Goliji. Osnovni ciljevi bili su: 1) ispitivanje varijabilnosti i odnosa populacija unutar i između vrsta u odnosu na koncentraciju diarilheptanoida u kori prirodnih populacija A. glutinosa i A. incana; 2) ispitivanje sezonske varijabilnosti diarilheptanoida u kori vrsta A. glutinosa i A. incana; 3) procena hemotaksonomskog značaja diarilheptanoida u ispitivanim vrstama; 4) procena mogućnosti primene diarilheptanoida u detekciji spontanih hibrida između A. glutinosa i A. incana; 5) ispitivanje varijabilnosti oblika, veličine i nervature lista u populacijama A. glutinosa i A. incana; 6) procena spontane hibridizacije između ove dve vrste na osnovu morfologije lista. Koncentracija najzastupljenijih diarilheptanoida (hirsutanonol-5-O-β-D-glukopiranozida, oregonina, hirsutanonola, alnuzida A, platifilozida i rubranozida A) u etanolnim ekstraktima kore ispitivanih populacija određena je pomoću UHPLC-MS/MS. Međupopulaciona varijabilnost koncentracije diarilheptanoida ispitana je pomoću parametarskih (ANOVA) i neparametarskih (Kruskal-Wallis) testova, analize glavne komponente (PCA) i diskriminantne analize (DA). Prvi uvid u kvantitativnu distribuciju odabranih diarilheptanoida kod A. glutinosa i A. incana je procenjen na osnovu analize populacija Rimski most i Sastavci. DA je pokazala 100% diskriminacije između tri grupe individua koje je izdvojila PCA, na osnovu čega je postavljena hipoteza da je jedna grupa od četiri individue hibridogenog porekla. Diarilheptanoidi su se pokazali dobrim hemotaksonomskim markerima na interspecijskom nivou i utvrđena je njihova mogućnost primene u detekciji spontanih hibrida. U narednoj vegetacijskoj sezoni, ispitana je sezonska, unutarpopulaciona, međupopulaciona i interspecijska varijabilnost koncentracije diarilheptanoida u dve geografski bliske (Rimski most i Sastavci) i dve relativno udaljene populacije crne i sive jove sa tipičnih staništa za svaku vrstu: Prilički kiseljak (A. glutinosa) i Golijska reka (A. incana). PCA je pokazala tendenciju jasnog međusobnog odvajanja grupa individua iz udaljenih populacija A. glutinosa i A. incana i preklapanja grupa individua iz geografski bliskih populacija ovih vrsta. Sve populacije su pokazale izrazit unutarpopulacioni varijabilitet, pri čemu je najheterogenija populacija Sastavci. Sezonska varijabilnost diarilheptanoida u kori uzorkovanoj u junu 2015. i aprilu 2016. godine ispitana je u populacijama Rimski most i Sastavci. Većina diarilheptanoida bila je prisutna u većoj koncentraciji u uzorcima sa istog staništa iz juna. Ovi rezultati mogu ukazati na postojanje različitih plastičnih odgovora kod ispitivanih vrsta u različitim sezonama. Geometrijskom morfometrijom je ispitana varijabilnost oblika lista u sve četiri populacije Alnus spp. PCA je pokazala kontinuum oblika listova, od oblika tipičnih za A. glutinosa do oblika tipičnih za A. incana, uz postojanje prelaznih oblika u oblasti preklapanja. Rezultati PCA ukazuju na morfološku bliskost listova vrsta A. glutinosa i A. incana, zatim na veliku varijabilnost i fenotipsku plastičnost individua u okviru populacija, kao i na verovatnoću postojanja hibrida. Potencijalni hibridi na koje je ukazala DA imaju intermedijarnu vrednost broja parova nerava (SN) između A. glutinosa i A. incana. Veličina lista, merena pomoću veličine centroida (CS), bila je značajno manja u populaciji Sastavci u odnosu na druge populacije; populacije A. glutinosa se nisu razlikovale prema SN i CS. Rezultati ukazuju na to da su alometrija lista, SN i CS relativno pouzdani indikatori delovanja sredinskih faktora.
AB  - In this study, two populations of Alnus glutinosa (L.) Gaertn. (Prilički kiseljak and Rimski most) and two populations of Alnus incana (L.) Moench (Golijska reka and Sastavci) were sampled on mountain Golija with the aims to investigate: 1) variability and relations of populations within and among species based on the concentration of diarylheptanoids in the bark of natural populations of A. glutinosa and A. incana; 2) seasonal variability of diarylheptanoids in the bark of A. glutinosa and A. incana; 3) the reliability of diarylheptanoids as chemotaxonomic markers in the studied species; 4) the reliability of diarylheptanoids for the detection of spontaneous hybrids between A. glutinosa and A. incana; 5) variability of leaf shape, size and venation in the populations of A. glutinosa and A. incana; 6) spontaneous hybridization between the studied species based on leaf morphology.
Six diarylheptanoids (hirsutanonol-5-O-β-D-glucopyranoside, oregonin, hirsutanonol, alnuside A, platyphylloside and rubranoside A) were quantified in bark ethanol extracts of four Alnus spp. populations by UHPLC-MS/MS. Interpopulation variability of diarylheptanoid concentration was investigated with ANOVA, Kruskal-Wallis test, principal component analysis (PCA) and discriminant analysis (DA).
Quantitative distribution of selected diarylheptanoids in the bark of A. glutinosa and A. incana was first analyzed in populations Rimski most and Sastavci. DA completely discriminates three groups of individuals that were implied by PCA. Based on the results, a hypothesis is proposed that the group of four individuals is of hybridogenic origin. Diarylheptanoids proved to be good chemotaxonomic markers at the interspecific level and may also reveal hybrid species.
In the next vegetation season, seasonal, within population, among population and interspecies variability of diarylheptanoid concentration were investigated in two geographically close (Rimski most and Sastavci), and two relatively distant populations
of black and grey alder sampled from the typical localities for the two species: Prilički kiseljak (A. glutinosa) and Golijska reka (A. incana). PCA shows clear separation of groups of individuals that belong to distant populations of A. glutinosa and A. incana, and partial overlapping of groups of individuals from geographically close populations Rimski most and Sastavci. All populations display pronounced intrapopulation variability. The most diversified is population Sastavci.
Seasonal variability of diarylheptanoid content was studied in the bark sampled from populations Rimski most (A. glutinosa) and Sastavci (A. incana) in two seasons (June 2015 and April 2016). The majority of diarylheptanoids are more abundant in samples collected in June than in April. These results may indicate different plastic responses of investigated species in different seasons.
The variability of leaf shape in four investigated alder populations was examined by geometric morphometry. PCA shows a continuum of leaf shapes between shapes typical for A. glutinosa and shapes typical for A. incana, with transitional shapes in the overlapping zone. These results implicate leaf morphological similarity of A. glutinosa i A. incana, great variability and phenotypic plasticity of individuals within populations and probable hybrid occurrence. Leaves from potential hybrid individuals indicated by DA have intermediate number of pairs of secondary leaf veins (SN) between A. glutinosa and A. incana. Leaf size was measured by centroid size (CS) which was significantly lower in population Sastavci (A. incana) compared to other populations; SN and CS did not show significant differences in populations of A. glutinosa. Leaf allometry, CS and SN seem to be good indicators of the influences of environmental factors.

AB  - Key message: Multivariate morphometric analyses were used for the first time to examine sexual dimorphism and shape variability of needles in natural populations of relict speciesTaxus baccataL.Abstract: Needle morphology and intraspecific variability of Taxus baccata L. were examined for the first time in Serbian natural populations (in the central Balkans). A geometric morphometric approach was used to assess size and shape variation of needles and to address questions of sexual dimorphism and phenotypic plasticity. Population-specific sexual size dimorphism was found. In the Tara population, females had larger needles than males and this was in accordance with earlier reports on T. baccata dimorphism. We found it unusual that in the other two populations, Kopaonik and Malinik, sexual size dimorphism was constrained and the sexes had needles of equal size. Multivariate analysis of needle shape revealed that the Tara population differed from the other two populations and was characterized by straighter, more symmetric needles. The absence of sexual size dimorphism and the less symmetrical shape of needles could be signs of a deviation from optimal conditions for yew in the Kopaonik and Malinik populations as regards mean annual temperature, precipitation, humidity and soil quality. There is also an indication that sexual size dimorphism in needles arises from a modification in female morphology and that female yews carry more information about climate. However, the conclusions presented in this study have certain limitations because of the small number of individuals in the Tara population (only 3 female and 4 male plants) that represent the quasi-total of adult yews at this site.

AB  - Ethnopharmacological relevance

Ethnobotanical knowledge and traditional medicinal practices from different parts of the world are of global importance and documentation of ethnobotanical, and ethnopharmacological data is a key prerequisite for further research in the area of herbal medicine and its implementation in clinical practice.
Aims

An attempt was made to evaluate the scientific output of research related to ethnobotany and herbal medicine in journals indexed in the subject area “Integrative and Complementary Medicine” in the period 2001–2013, in order to ascertain research trends in both subdisciplines.
Materials and methods

All articles related to ethnobotany and herbal medicine, extracted from journals included in the field of I&C Medicine and published in the period 2001–2013, have been analyzed for general bibliometric data, and specific data: ethnobotanical data (geographic, floristic, pharmacological, sociological and other relevant data) and phytotherapeutic data (type of applied herbal medicine, plant species studied, pharmacological activity of studied plant species and disease and disorder type studied on a particular model).
Results

In the studied period, the number of articles dealing with ethnobotany and herbal medicine increased 6.3-fold. Articles related to ethnobotanical studies documented medicinal flora from 81 countries, either giving an overview of overall medicinal flora, or presenting the ethnomedicinal aspect of the use of plants for the treatment of ailments typical to the studied area. Additionally, the authors provided significant information on the methods of use and herbal preparations. In herbal medicine studies, plants, traditional plant remedies, herbal medicinal products and active herbal compounds were tested for many of pharmacological activities (146), with the curative activity emerging as most frequently tested. Out of 39 model systems, most of the studies were carried out under controlled in vitro conditions (4589 articles), followed by rat in vivo (2320), human in vivo (1285), mouse in vivo (955), and on agents of pathogenic diseases (887); more than 800 medical disorders were treated.
Conclusions

The study revealed the regions most studied for new records of floristic and ethnomedicinal diversity, the most frequently studied plant species, and the most promising therapeutic indications for the integration of herbal remedies in the curative process, as ascertained from the selected bibliographic databases.

AB  - The composition of the essential oil of the twigs and needles of Taxus baccata L. from three natural populations in Serbia has been determined by GC/MS analysis. Of the 91 detected compounds, 87 were identified. The most abundant compound classes were aliphatic alcohols, terpenes, aliphatic hydrocarbons, and aliphatic aldehydes, which together comprised ca. 86.92% of the total oil composition. The dominant constituents were oct‐1‐en‐3‐ol (23.48%), (3Z)‐hex‐3‐en‐1‐ol (11.46%; aliphatic alcohols), and myrtenol (11.38%; oxygenated monoterpene). The PCA of 22 selected compounds revealed differentiations of populations based on geographic distribution. The CA showed that Populations I and II from the Dinaric Alps were similar, and that Population III from the Balkan mountain system was distinct. This was the first investigation of interpopulation variability of T. baccata populations based on essential oil composition. The results of this study were compared with those of previous studies concerning volatile compounds produced by Taxus species. The results indicate that the essential oil content of T. baccata populations from this study is unique, mostly resembling the population from southeast Serbia.

AB  - The patterns of tree-related stress research depended on their cultivation status and were statistically highly significant in all analyses. Non-cultivated tree species were studied more, cited more often, by authors from differing countries, with emphasis on different tree processes, stress types and research areas, and published in different journals. From 2001–2014, 4128 articles in 586 different academic journals dealt with tree stress. A majority of journals published stress-related research either on cultivated or on non-cultivated tree species. The articles were averagely cited 17 times, the five dominant journals being Acta Horticulturae, Tree Physiology, Trees—Structure and Function, Forest Ecology and Management and PLoS ONE. Research was published by authors from 109 countries, authors from China, USA, Spain, Brazil and Italy being the most productive. International collaboration was present in 21 % of the articles. A total of 1141 tree species were studied from 366 genera. The dominant species studied were Olea europaea, Malus x domestica, Pinus sylvestris, Prunus persica, Picea abies. Around ¾ of the articles were single species studies. Water stress, followed by drought stress, salt stress, abiotic stress, and environmental stress were the most studied types with over 90 % articles dealing with a single stress type. Physiological and ecophysiological research of trees exposed to stress dominated, followed by molecular biology and biochemistry, genetics, ecology. Tree growth was the most studied process/activity, followed by photosynthesis, gene expression, stomatal conductance and water status. An increase in “-omics” type research was observed in recent years in cultivated tree research.

AB  - In studies of population variability, particular attention has to be paid to the selection of a representative sample. The aim of this study was to assess the size of the new representative sample on the basis of the variability of chemical content of the initial sample on the example of a whitebark pine population. Statistical analysis included the content of 19 characteristics (terpene hydrocarbons and their derivates) of the initial sample of 10 elements (trees). It was determined that the new sample should contain 20 trees so that the mean value calculated from it represents a basic set with a probability higher than 95 %. Determination of the lower limit of the representative sample size that guarantees a satisfactory reliability of generalization proved to be very important in order to achieve cost efficiency of the research.

AB  - Out of a total number of tree species in Serbian flora, 28% are hermaphrodites, 43% are monoecious and 29% are dioecious. The dendroflora appears to have a larger proportion of unisexual than hermaphrodite species. The monoecious system is the dominant unisexual system within the tree species in Serbia. The possible sex differentiation by RAPD markers and Correspondence Analysis was examined in a population of Fraxinus ornus var. angustifolia. On the basis of 6 selected RAPD bands which contribute to the differentiation in frequency between male and hermaphrodite individuals, Correspondence Analysis visualized the following tendency: 20 trees of each variety were separated into two groups that mainly correspond to sexual types. Our results showed that RAPD markers assisted by Correspondence Analysis could be used in identifying male and hermaphrodite individuals in F. ornus varieties.

AB  - The present study investigated the influence of exogenously added jasmonic acid on the morphogenesis and the concentration of photosynthetic pigments in the selected bryophite species: Atrichum undulatum, Bryum alpinum, B. argenteum. The moss A. undulatum was grown on the sugar enriched MS medium, whereas the species B. alpinum and B. argenteum were grown on the MS media without sugars. The plants were grown for six weeks in long-day conditions (16/8 h photoperiod). Four different jasmonic acid concentrations were added to the media. Biomass production in species A. undulatum and B. alpinum increased in the presence of lower concentrations of exogenously added jasmonic acid compared to control biomass production. The analysis of photosynthetic pigment concentrations was conducted as well. This analysis showed an increase of total pigment concentrations at lower levels of applied jasmonic acid and a decrease of pigment concentrations at higher levels of the applied jasmonic acid. No significant dependence on the levels of pigments with regard to the concentration of jasmonic acid was noted in the case of B. argenteum.
