AB  - The pedunculate oak (Quercus robur L.) is economically and ecologically one of the most
significant tree species in Serbia, however, little is known about the influence of the riverbed distance and its water supply on ecophysiological responses of this species. Given the limited information on the light-response curve of photosynthesis for oaks in southwest Srem, Serbia, the aim of this paper is to enhance understanding of their ecophysiological responses in this context. Maximum assimilation rate (Amax), the quantum yield (Ф), and light compensation point (LCP) were compared in adult trees situated along the transect from the river: (1) close to the river, (2) intermediate, (3) farthest from the river, and (4) forest reserve (second closest), with the first three transects being managed forests and the last one being an unmanaged forest reserve. The measurements were conducted in July during the first evidence of drought. The highest Amax rates were measured in all light intensities on the site closest to the river and the smallest on the site that was most distant to the water source. The most efficient were trees close to the river and the ones in the forest reserve. No significant difference between compensation points was confirmed for the studied groups of trees, although the forest reserve trees showed slightly higher values. The results demonstrated clear response between transects, which followed the distance from the riverbed. Pedunculate oak's reliance on groundwater is in tight relation with ecophysiological processes in trees; groundwater depletion may threaten its survival in areas distant from the river.

AB  - The influence of different groundwater table depths on pre-dawn water potential (PWP), soil moisture content and antioxidant activity (FRAP, RSC against DPPH·, NO and ABTS radicals) of adult pedunculate oak (Quercus robur L.) trees was assessed in three managed stands (localities 1-3) and one unmanaged (locality 4 - forest reserve). The study sites were located within single forest complex at different distances from the Sava riverbed. The measurements were performed during July 2015, when the first evidence of drought was evidenced. We hypothesised that the trees at locations farther from the river would be more drought-stressed due to lower groundwater depth and will show higher antioxidant capacity. Indeed, trees at localities 2 and 3 were more drought-stressed as compared to trees at locations 1 and 4, as indicated by the PWP results. Since antioxidant capacity can be directly correlated to drought tolerance, the present results
indicate a higher antioxidant capacity in leaf extracts from locality 3, but also good oxidative adaptation in leaf extracts from locality 4, where the obtained values for almost all examined antioxidant tests were without statistically significant differences compared to those on locality 3. Obtained results may help to explain differences in biochemical responses to water deficit stress of pedunculate oak trees from different microsites within the single forest complex and provide us
valuable information about intra-species drought resistance. Therefore, this can be an important tool for the improvement of breeding strategies and artificial regeneration plans for pedunculate oak in dry lowland regions.

AB  - Oak powdery mildew (Erysiphe alphitoides (Griffon and Maubl.) U. Braun and S. Takam.)) is one of the most common foliar pathogenic organism of oaks, exploiting harmful effects, particularly on young seedlings. To assess and evaluate these negative effects, an experiment was conducted under semi-controlled conditions with 20 one-year-old seedlings of Quercus robur L. infected with E. alphitoides, half of them showing 50% of leaf coverage by epiphytic mycelia and the other half a coverage of 75%. The results of the present study have shown that all observed parameters of chlorophyll a fluorescence transient were highly effective in the detection of severe biotic stress. Moreover, the studied parameters of slow fluorescence kinetics were also considerably influenced, with the coefficient of non-photochemical fluorescence quenching and the Stem-Volmer type non-photochemical fluorescence quenching parameters showing the fastest responses. In case of leaf stomatal traits, the decrease of stomata guard cell width coupled with the increase of stomatal density was observed as the protective mechanism of Q. robur against the stressor. The overall results showed the adverse effects of powdery mildew infection on the photosynthesis of pedunculate oak seedlings, which progressed in time and depended on the severity of the infection. The importance of the results of the present study lays in evaluation and monitoring of the effects of powdery mildew development on the photosynthetic apparatus of one-year-old Q. robur seedlings, which is the most vulnerable stage for the infection by the mentioned pathogen.

AB  - The general aim of this work was to compare the leaf-level responses of different protective components to water deficit and high temperatures in Quercus cerris L. and Quercus robur L. Several biochemical components of the osmotic adjustment and antioxidant system were investigated together with changes in hormones. Q. cerris and Q. robur seedlings responded to water deficit and high temperatures by: (1) activating a different pattern of osmoregulation and antioxidant mechanisms depending on the species and on the nature of the stress; (2) upregulating the synthesis of a newly-explored osmoprotectant, dimethylsulphoniopropionate (DMSP); (3) trading-off between metabolites; and (4) modulating hormone levels. Under water deficit, Q. cerris had a higher antioxidant capacity compared to Q. robur, which showed a lower investment in the antioxidant system. In both species, exposure to high temperatures induced a strong osmoregulation capacity that appeared largely conferred by DMSP in Q. cerris and by glycine betaine in Q. robur. Collectively, the more stress-responsive compounds in each species were those present at a significant basal level in non-stress conditions. Our results were discussed in terms of pre-adaptation and stress-induced metabolic patterns as related to species-specific stress tolerance features.

AB  - In the present study we compared the physiological performances of Prunus avium L., Robinia pseudoacacia L., Juglans nigra L., and Populus x euramericana cl. Pannonia, planted at the coal mine tailings of the Mining Basin "Kolubara" (Serbia), to assess the potential of different tree species for land reclamation. The measurements were conducted during three consecutive years characterized by contrasting climatic conditions (wet and drought). The results showed that the rate of net photosynthesis (A), stomatal conductance (gs) and transpiration rate (E) sharply declined in two dry years in all tree species. These trends were particularly evident for R. pseudoacacia and J. nigra, in which A, gs and E were twice as low during the dry years. On the other hand, R. pseudoacacia and P. x euramericana cl. Pannonia seedlings were characterized by the highest water-use efficiency and intrinsic water-use efficiency during the dry years, indicating that these species are more efficient responders to drought, due to their ability to maintain a balance between the loss of water and the CO2 assimilation rates. The survival rate of the examined tree species was high ( GT 86%) and increased in the following order: P. avium  LT  J. nigra  LT  R. pseudoacacia  LT  P. x euramericana cl. Pannonia. Based on the obtained results we recommend R. pseudoacacia and P. x euramericana cl. Pannonia as a good solution for afforestation and revitalization of degraded habitats, such as coal mine tailings, although high survival rate, observed in P. avium and J. nigra, makes these two species a candidate for planting during degraded sites reclamation, as well.

AB  - The present study focuses on the estimation of the effects of oak powdery mildew on
the leaf physiological traits of Quercus robur L., based on the combination of chlorophyll
a fluorescence parameters with leaf gas exchange parameters. In order to have a better
insight into the effects of Erysiphe alphitoides (Griffon and Maubl) U. Braun and S.
Takam. on the light-harvesting apparatus, a greenhouse semi-controlled experiment
was performed with 50 individuals of one-year-old seedlings. Half of them were kept
under optimal conditions, and the other half were infected with the studied obligate leaf
pathogen. The criteria for carrying out the measurements was a visual coverage of the
leaf surface with epiphytic micelia above 75%.
The results of the present study showed a highly significant decrease of net
photosynthesis and an increase of substomatal CO. concentration of leaves infected
with E. alphitoides above 75%. The net photosynthesis was reduced by 43.9%,
meanwhile the 65.7%. increase of substomatal CO: concentration was even more
substantial. Moreover, the effects of oak powdery mildew on all of the observed
parameters of fast kinetics of chlorophyll a fluorescence were found to be statistically
significant. However, the parameters of the pulse amplitude modulated fluorescence
were just mildly affected by the examined pathogen, with only the minimal and maximal
fluorescence values of previously dark adopted leaves showing a significant difference.
The results of this study showed the effectiveness of chlorophyll a fluorescence
parameters in detection of severe biotic stress conditions, on the example of highly
infected oak leaves with E. alphitoides. Follow up studies should be conducted in order
to determine the effects of oak powderily mildew in early and mild infection stages,
based on the parameters of chlorophyll a fluorescence.

AB  - The aim of the present study was to evaluate the effect of one of the
most important foliar diseases, powdery mildew, on the leaf physiological traits of Quercus
robur L. using chlorophyll a fluorescence parameters in combination with parameters of
leaf gas exchange. For this purpose, greenhouse semi-controlled experiment was conducted
with 25 one-year-old seedlings kept in optimal conditions, and the same number of seedlings
infected with the mentioned pathogen. Measurements were carried out when the coverage
of epiphytic micelia visually reached more than 75% of the surface of leaves in the infected
seedlings.
The results of gas exchange measurement showed that Erysiphe alphitoides (Griffon
and Maubl.) U. Braun and S. Takam caused a significant reduction of net photosynthesis (A)
and a significant increase in substomatal CO2 concentration (Ci). Furthermore, considering the
fast kinetics of chlorophyll a fluorescence, all of the observes parameters were significantly
affected by oak powdery mildew. On the other hand, pulse amplitude modulated fluorescence
parameters were mildly affected, with only minimal (Fo’) and maximal (Fm’) fluorescence
of dark adopted leaves showing significant difference. This study presented the possibility of
usage and the effectiveness of chlorophyll a fluorescence parameters in detection the severe
stress conditions, on the example of leaves infected with oak powdery mildew over 75%. Some
additional studies should be conducted in the future to determine the possibility of usage
and the effectiveness of the observed fluorescence parameters of fast kinetics in detection
of mild and early stress.
AB  - Циљ рада био je да се процени утицај храстове пепелнице, као једне од најзначајнијих фолијарних болести на физиолошке карактеристике листа храста лужњака (Quercus robur L.).

Мерења су вршена када је прекривеност листа епифитном мицелијом визуелно достигла више од 75% површине покривености лишћа.
Резултати мерења размене гасова указали су на то да је храстова пепелница имала значајан утицај на смањење нето фотосинтезе (А), као и на повећање интерцелуларне концентрације CO2 (Ci). Поред наведеног, статистички значајна разлика је утврђена за све посматране параметре брзе кинетике флуоресценције хлорофила а између здравих листова и листова заражених преко 75% храстовом пепелницом. Међутим, поменути патоген имао је слаб утицај на параметре импулсне амплитудне модулације флуоресценције. Једино су минимална (Fo’) и максимална (Fm’) флуоресценција замрачених листова показале значајне разлике између контролних и пепелницом заражених листова садница. У раду је приказана могућност и ефикасност коришћења параметра флуоресценције хлорофила а у детекцији јаког стреса на примеру листа зараженог пепелницом изнад 75%. Даља истраживања требало би усмерити ка испитивању могућности и ефикасности коришћења параметара брзе кинетике флуоресценције за детекцију почетног и благог стреса.

different treatments in semi-controlled conditions: optimal soil moisture – control (K), drought
followed by recovery after the restoration of the optimal soil moisture (T1) and the treatment

photosynthesis were examined in correlation with the applied treatments. Treatment T2 was
influenced to a significant reduction in the intensity of photosynthesis, stomatal conductance
and instantaneous water use efficiency, as well as to a significant increase in the intercellular

Ten stomatal traits (stomatal density (SD), guard cell length (LA) and width (WB), stomatal aperture length (La) and width (Wb), pore surface of guard cell (SPSLAWB), pore surface of a widely opened pore (SPSLaWb), coefficient (SSC), potential conductance index (PCI) and relative stomatal pore surface (RSPS)) were examined using methods of univariate (ANOVA and Tukey's HSD test) and multivariate statistical analyses (principal component analysis (PCA), discriminant analysis and cluster analysis). The results obtained provide significant insight into the genetic diversity and differentiation of European beech provenances and confirmed high genetic variability within and between examined European beech provenances, according to all examined parameters. Differences at the intra-provenance level had a bigger impact on most of the examined stomatal traits (with 70-80% of total variation), while differences at the interprovenances level accounted for only 20-30% to the total expected variance. The results of PCA and canonical analysis suggest ecotypic pattern of genetic variability related to seed origin, which influenced leaf stomatal traits in F. sylvatica provenances. Forward stepwise discriminative analysis showed that WB, SD, PCI, SPSLaWb and Wb traits accounted for the same level of discrimination, as all the examined stomatal parameters together. However, the analysis detected considerably small correct allocation of the model that included all examined traits (only 38.85%). In order to discriminate examined beech provenances more precisely, additional phenotypical traits (e.g. morphological, physiological, etc.) should be included in the model.

AB  - Aim of study: In the present paper the nature and level of co-dependence between leaf functional traits and intrinsic water-use efficiency (WUEi) were studied in one-year-old Quercus robur L. seedlings, grown in a common garden experiment under moderate drought conditions. The study was established to identify those traits that might potentially be utilized to improve leaf-level WUEi, and therefore be used in breeding programmes to enhance drought adaptation of Q. robur. Area of study: The study was carried out at the common garden site within the UNESCO Biosphere Reserve Mura-Drava-Danube. Material and methods:The study involved one-year-old seedlings of eight half-sib lines of Q. robur. Eighteen leaf parameters were analyzed; i.e. physiological, biochemical, morphological and anatomical. The data were processed using multivariate statistical methods: a) principal component analysis, b) stepwise regression analysis, and c) path coefficient analysis. Main results: The results showed that leaf stomata traits, particularly stomatal density (SD), and leaf dry mass per unit leaf area (LMA) were the most important traits, closely associated with WUEi. Stomatal density achieved the highest score on PC1 (0.825), in which WUEi had the highest loading (0.920), as well. SD was also included first in stepwise regression model. Research highlights: These results demonstrate that under moderate water stress WUEi in Q. robur half-sib lines were mainly the result of the plants' structural acclimation to surrounding environmental conditions.

AB  - The aim of this study was to examine the number of species, their coverage, present life forms and the diversity of dendroflora of an urban block (N 45°15', E 19°48') in the Novo naselje district of Novi Sad. The results manifested that, in regards of coverage, the biggest influence on the composition of the dendroflora had interspecies hybrida) species, with a number of 1039 individuals (38%). On the other hand, introduced species were present in higher numbers (918 individuals, 32%) than autochthonous (799 individuals, 30%). Analysis of the representation of phanerophyt (Ph) life forms in the composition of the urban vegetation, lead to the conclusion of the dominance (1504 individuals, 55%) of nanophanerophyts (nPh), bushes with height up to 2 m. The diversity of the dendroflora was calculated with the Simpson's index of heterogeneity resulting in 0.901, as well as with the reciprocal Simpson's index of 10.113, pointing out to the richness of woody species. Significance of these findings is discussed in relation to the creation an unified cadaster of green spaces of Novi Sad, purposed for monitoring and maintenance of the woody species.

AB  - The seedlings of pedunculate oak (Quercos robur L.) were exposed to different ater contents (non-limiting and severe drought) for 30 days in a greenhouse in order to examine the effects of prolonged summer drought on diurnal fluctuations of gas exchange parameters. Results showed that, in control treatment, diurnal course of photosynthetic rate (A), transpiration rate (E) and stomatal conductance (g(s)) was bimodal, showing clear midday depression. In stress treatment, the diurnal dynamics of A exhibited an atypical double-peaked pattern, whereas the diurnal change in E and g(s) presented a single-peaked curve. A positive and significant correlation between A and g(s) was observed in well-watered as well as in drought stressed plants, whereas intercellular CO2 concentration (Ci) increased with decreasing A rate. Therefore, we might assume that in both treatments die largest part of the reduction in photosynthesis was caused by stomatal closure; however, this finding does not preclude the existence of alternative mechanisms that may also have affected photosynthesis. The diurnal dynamics of instantaneous water use efficiency (WUE) exhibited maximum values in the early morning, afterwards it decreased during late morning and throughout the afternoon with the decline being greater in the stressed than in the control plants. Comparing to the control, the plants subjected to permanent water deficit have increased intrinsic water use efficiency (WUEi) during the early morning, pointing out on minimized loss of water per fixed CO2. Leaf temperature (TI), as an environmental factor, was in a significant negative correlation with WUE, and in a positive one with E, in both treatments. The results of the study point to the adverse effect of prolonged experimental drought on net photosynthesis and other gas exchange parameters in pedunculate oak leaves, allowing them to he used as an important indicator of environmental conditions and trends in climate change.

AB  - Klimatske promene koje se intenzivno dešavaju u poslednjih nekoliko decenija imaju globalni efekat na vegetaciju i šumski pokrivač, što dovodi do velikih transformacija u prirodnim resursima i strukturi pejzaža. Uticaj klimatskih promena na vrste često se procenjuje korištenjem modela distribucije vrste (SDMs). Ovi modeli koriste podatke o životnoj sredini i prisustvu/odsustvu neke vrste, utvrđuju njihov međusobni odnos, te na drugim lokacijama pokazuju da li su uslovi sredine pogodni ili ne za postojanje te vrste. Pošto se modeli lako implementiraju, oni se danas koriste u velikoj meri za razmatranje različitih pitanja u istraživanju životne sredine, kao i za pružanje smernica za primenjena istraživanja. Cilj ovog rada je razviti i oceniti Random Forest (RF) model zasnovan na trenutnim podacima o rasprostranjenju šuma evropske bukve, ekoloških i klimatskih karakteristika na teritoriji Srbije. Dobijeni model će poslužiti kao osnova za izgradnju modela koji će predvideti distribucije vrste u budućnosti.Tačnost modela je ispitana upotrebom adekvatnih statističkih metoda. Analiza True Skill Statistic (TSS) ukazuje na veliku tačnost modela (TSS = 0.87, specifičnost =87.81, senzitivnost =99.44). Tačnost je potvrđena analizom površine ispod ROC (Receiver Operating Characteristic) krive (AUC) (AUC=0.97, specifičnost =88.01, senzitivnost=99.27). Takođe, rezultati ukazuju na potrebu za uključivanjem više ekološki relevantnih topografskih varijabli prilikom projektovanja modela distribucije vrsta u odnosu na klimatske promene, naročito za vrste koje su u korelaciji sa topografijom, odnosno visinskom raspodelom.
AB  - Climate change that has been intensively occurring in the last few decades has a global effect on vegetation and forest cover, leading to major transformations in natural resources and the landscape structure. The impact of climate changes on species is often estimated using a species distribution models (SDMs). These models use environmental data and presence/absence of a species, determine their mutual relationship, in order to show on other locations whether environmental conditions are suitable or not for the existence of this species. Since models are easy to implement, they are now widely used to consider various issues in environmental research, as well as providing guidance for applied research. The aim of this paper is to develop and evaluate the Random Forest (RF) model based on current data on existence of European beech, ecological and climatic characteristics in the territory of Serbia. The model obtained will serve as the basis for building a model that will foresee the distribution of species in the future. The accuracy of the model was tested using adequate statistical methods. The True Skill Statistic (TSS) analysis indicates a high accuracy of the model (TSS = 0.87, specificity = 87.81, sensitivity = 99.44). The accuracy was confirmed by the analysis of the area under the ROC (Receiver Operating Characteristic) curve (AUC) (AUC = 0.97, specificity = 88.01, sensitivity = 99.27). Also, the results pointed to the need to include more environmentally relevant topographic variables when designing a SDM in relation to climate change, especially for species that are correlated with topography.

Pošto se modeli lako implementiraju, oni se danas koriste u velikoj meri za razmatranje različitih pitanja u istraživanju životne sredine, kao i za pružanje smernica za primenjena istraživanja. Cilj ovog rada je razviti i oceniti Random Forest (RF) model zasnovan na trenutnim podacima o rasprostranjenju šuma evropske bukve, ekoloških i klimatskih karakteristika na teritoriji Srbije. Dobijeni model će poslužiti kao osnova za izgradnju modela koji će predvideti distribucije vrste u budućnosti.Tačnost modela je ispitana upotrebom adekvatnih statističkih metoda. Analiza True Skill Statistic (TSS) ukazuje na veliku tačnost modela (TSS = 0.87, specifičnost =87.81, senzitivnost =99.44). Tačnost je potvrđena analizom površine ispod ROC (Receiver Operating Characteristic) krive (AUC) (AUC=0.97, specifičnost =88.01, senzitivnost=99.27). Takođe, rezultati ukazuju na potrebu za uključivanjem više ekološki relevantnih topografskih varijabli prilikom projektovanja modela distribucije vrsta u odnosu na klimatske promene, naročito za vrste koje su u korelaciji sa topografijom, odnosno visinskom raspodelom., Climate change that has been intensively occurring in the last few decades has a global effect on vegetation and forest cover, leading to major transformations in natural resources and the landscape structure. The impact of climate changes on species is often estimated using a species distribution models (SDMs). These models use environmental data and presence/absence of a species, determine their mutual relationship, in order to show on other locations whether environmental conditions are suitable or not for the existence of this species. Since models are easy to implement, they are now widely used to consider various issues in environmental research, as well as providing guidance for applied research. The aim of this paper is to develop and evaluate the Random Forest (RF) model based on current data on existence of European beech, ecological and climatic characteristics in the territory of Serbia. The model obtained will serve as the basis for building a model that will foresee the distribution of species in the future. The accuracy of the model was tested using adequate statistical methods. The True Skill Statistic (TSS) analysis indicates a high accuracy of the model (TSS = 0.87, specificity = 87.81, sensitivity = 99.44). The accuracy was confirmed by the analysis of the area under the ROC (Receiver Operating Characteristic) curve (AUC) (AUC = 0.97, specificity = 88.01, sensitivity = 99.27). Also, the results pointed to the need to include more environmentally relevant topographic variables when designing a SDM in relation to climate change, especially for species that are correlated with topography.",

AB  - U istraživanju je posmatrano ukupno 17 stabala hrasta lužnjaka (Quercus robur L.) koji se nalaze u drvoredu u Novom Sadu, na Bulevaru vojvode Stepe (N 45o 25'61.75', E 19 o79'73.47'). Sa svakog stabla je tokom oktobra 2017. godine metodom slučajnog uzorka sakupljeno po 50 žira - radi istraživanja varijabilnosti genotipova na osnovu morfoloških osobina ploda. Ispitivani su morfološki parametri dužina ploda (mm), širina ploda (mm), koeficijent izduženosti (odnos dužine i širine ploda) i masa ploda (g). Rezultati jednofaktorske analize varijanse ukazuju na statistički značajne razlike između plodova posmatranih genotipova hrasta lužnjaka. U slučaju parametra izduženosti ploda (odnos dužine i širine ploda), utvrđena F vrednost se pokazala kao najveća (F= 99.36) i na nivou je statističke značajnosti od p LT 0.001. Za dužinu ploda utvrđena je vrednost F=97.86 na nivou značajnosti od p LT 0.001, za masu ploda F=5.844 na nivou značajnosti od p LT 0.05, dok se razlike između srednjih vrednosti širine ploda pokazale kao statistički ne signifikantne. Na osnovu analiziranih podataka moguće je izdvojiti individue 1,2,6,11,12,13,16,17, koje se po poželjnim karakteristikama ploda (veća dužina, širina i masa ploda) izdvajaju od ostalih i predstavljaju osnovu za dalja istraživanja. U narednom periodu će biti sprovedena istraživanja vezano, kako za uticaj veličine semena na morfološke karakteristike sejanca hrasta lužnjaka, tako i na otpornost sejanaca prema abiotičkim faktorima stresa (suša, itd.).
AB  - In this experiment seventeen Pedunculate oak trees (Quercus robur L.) were observed, located in an alley on the Boulevard of Vojvode Stepe (N 45o 25'61.75', E 19 o79'73.47') in Novi Sad, Serbia. From each tree, fifty acorns were randomly collected for the purpose of researching the variability of the genotypes based on the morphological characteristics of their fruits. The characteristics researched were the length and width of the fruit (mm, respectively), coefficient of elongation (ratio of the fruit length and width) and the weight of the fruit (g). Results of the one-way ANOVA show that there are statistically significant differences between the fruits of the observed Pedunculate oak genotypes. In the case of the coefficient of the elongation, the calculated F value turned out to be the highest (F=99,36), and it is on the level of statistical significance p LT 0.001. For the length of the fruit the determined value of F=97.86 is on the level of significance p LT 0.001, for the weight of the fruit F=5.884 is on the level of significance p LT 0.05, but the differences between the mean values of the width of the fruits are not shown as statistically significant. The analysis of the data from this research shows that genotypes 1, 2, 6, 11, 12, 13, 16 and 17 stands out from the others based on the desired characteristics of their fruits, and they present an interesting base for further research. In the following period experiments will be conducted regarding the effects of seed dimensions on the morphological characteristics of Quercus robur L. seedlings, and the resistance of seedlings to abiotic factors of stress (draught, etc.).
