Opis:
The paper shows differences in morphological and anatomical features of the Scots pine (Pinus sylvestris L.) growing on former agricultural and forest lands. It was found that at the same age and in the same climatic conditions Scots pines from former agricultural land had larger stem dimensions and needle sizes as compared with the trees growing on forest land. These results lead to an interesting conclusion connected with future afforestation and reforestiation in the Krynki Forest District.

Opis:
The anatomical and morphological diversity of Scots pine (Pinus sylvestris L.) needles was investigated in nine Polish populations grown on the experimental plots at the Forest Experimental Station of the Warsaw University of Life Sciences – SGGW (Rogów, Central Poland). The experiment started in 1966 and the needle samples were collected from the trees cut down during the thinning treatment in 2016. The following needle traits were measured: (1) length, (2) width, (3) thickness, (4) cross−sectional area of the transfusion tissue, (5) epidermis thickness, (6) width to thickness of the needle cross section ratio, (7) distance between the vascular bundles, (8) number of resin ducts, and (9) length of the needle scales. The results showed that trees from the provenances differ with respect to the studied needle features, however, the differences, for individual traits, are relatively small and in most cases are statistically insignificant as measured by the Kruskal−Wallis test. Statistically significant differences (p<0.05) were found only in case of such features as the number of resin ducts and the length of needle scales. The results may suggest that the environmental conditions of the Polish lowland are not sufficiently diversified to induce clear differences between the individual morphological and anatomical traits of pine needles. However, despite the relatively small differences between the studied populations regarding individual traits, the use of the UPGMA (Unweighted Pair Group Method with Arithmetic mean) dendrogram, taking into consideration the combined effect of all the examined traits of needles, allowed to separate geographically the tested Polish provenances into three groups: I – mid−western (Rogów, Bolewice, Spała, Karsko, Gubin, Tabórz), II – north−eastern (Rospuda, Starzyna) and III – south−eastern (Janów Lubelski). It is suggested that this may be related both to the ability of Scots pine to adapt to local conditions as well as the possibility that the geographical groups of tested populations originated from three different main glacial refugia.

The effect of hard coal fly ash applied on surface of forested (formerly arable) rusty soil on chemical composition of soil surface horizons was evaluated in field experiments conducted between the years 1992-1995. The application of fly ash at the dose 15, 30, 60 and 120 t ha-1 on the soil surface caused a decrease of acidity of soil surface layer which was dependent on the fly ash rate. The deacidification of soil lasted only two years. The application of fly ash increased also the content of macro- and microelements in the soil as well as in Scotch pine needles.

Opis:
Pine needles and foodstuffs collected from Beijing, China, were analyzed by instrumental neutron activation analysis (INAA) combined with organic solvent extraction for total halogens, extractable organohalogens (EOX) and extractable persistent organohalogens (EPOX). The INAA detection limits are 50 ng, 8 ng and 3.5 ng for Cl, Br and I, respectively. The contents and distribution patterns of organohalogens in these samples are reported. EOCl accounted for 0.013 0.016% and 1.6 2.7% of the total chlorine in yogurt and apples, respectively, which suggested that chlorine in foodstuffs mainly existed as inorganic species and non-extractable organochlorines. EOCl contents in pine needles and foodstuffs were noticeably higher than those of EOBr and EOI. For pine needles, yogurt and apples, 1.6 34%, 23 58% and 29 35% of EOCl remained as extractable persistent organochlorine (EPOCl), respectively. Pine needle containing higher EOCl contents in chemical industrial and traffic hub areas indicated that chemical industries and exhaust emission from vehicle were the main sources of organochlorines in the Beijing's air. The relative proportions of the known organochlorines (such as HCHs, DDTs, chlordanes, heptachlor, HCB and PCBs) to the total EOCl and EPOCl were 0.04 1.6% and 0.7 21.5%, respectively, which implied that the identity of species of a major portion of the EOCl and EPOCl measured in pine needles was unknown.

Opis:
Mutational witches’ brooms (WBs) in conifers are widely used in landscaping. However, there have been few WB morphology and anatomy investigations. The needle structure of witches’ brooms and normal crown (NC) in Pinus sibirica clones was studied, using light microscopy technique. The aim was to compare the needle structure in WBs and NC and to reveal the effects of the mutation on the needle traits. Three WB and NC pairs of clones from the same trees were used in the study. WBs in the parental trees were characterized by different density in the affected part of the tree. In all pairs, WB needles were shorter and thinner than in NC. In contrast to NC needles, WB needle length was positively correlated with resin duct total area and width of endodermis cell. Thus, the affected needles had a changed structure, and the effect of the mutation was determined by mutation expression.

Opis:
The aim of this study was to characterize the turfosa form of Pinus sylvestris from the Gazwa peat bog reserve in terms of 16 anatomical needle traits and to determine whether pines with a typical morphotype inhabiting the peat bog have been so successful thanks to hybridization with the unique tufosa ecotype. Investigations were conducted on three phenotypic groups of Scots pine growing in the peat bog. The first two groups consisted of 30 tufosa trees at the age of 117-217 years and 20 trees at the age of 30-85 years. The third group consisted of typical pines represented by 10 trees at the age of 20-55 years. In total 30 trees of typical pine, surrounding the peat bog, at the age of 100-150 years served as outgroup. Descriptive statistics, analysis of variance with the F test, Tukey's test, and a number of multivariate analyses were used to estimate differences between the studied groups of trees based on 16 anatomical needle characteristics. The old turfosa form from the Gazwa reserve proved to be a unique and relict peat bog pine, as it was shown by the differences in 10 analyzed needle traits in comparison to pine with a typical morphotype growing in the areas surrounding the peat bog. The young typical pines have adapted to conditions found in the peat bog owing to hybridization with the turfosa forms. The young turfosa trees differed from the old turfosa trees and also they have probably been of a hybrid origin. The old turfosa form from the Gazwa reserve is a threatened ecotype due to its hybridization with pines from the population surrounding the peat bog.

Opis:
We investigated the phenotypic variation of five morphological needle characters of Scots pine (Pinus sylvestris L.) in three populations. Two of the populations occurred in bogs and the third one formed a degraded fresh pine forest showing some features of a dry pine forest. The greatest variation was found in characters a (needle length), b and d, denoting the number of stomatal rows respectively on the convex and flat sides of the needle. Conversely, characters c and e (average number of stomata per 2 mm of needle length on the convex and the flat side of the needle) were stable, with little interindividual variation. The two bog populations and the dryland population exhibited different sets of character correlations. The interpopulation differentiational detected on the basis of morphological character expression was markedly influenced by both the different edaphic conditions, and the distinct genetic structure of the studied populations.

Opis:
The process of plant selection by insects is mediated by repellents and attractants. Several compounds may be involved in this interaction. Thus intraspecific variation of the compounds concentration play an important role in the herbivory. The best tool for the characteristic of this variation is chemometrics. The strategy of the analysis with the use of literature data on terpenes and sesquiterpenes variations in Pinus caribaea needles in relation to Atta laevigata herbivory is exemplified herein. Simple cluster analysis and principal components analysis were used for the data study. Two factors were found to be sufficient to describe total variation in more than 90%. Factor 1 is responsible for repellent properties. From factor loading, the relevant chemical compounds were identified.
Wiele różnych substancji chemicznych zawartych w roślinach wpływa na zachowanie owadów, pełniąc funkcje repelentów lub atraktantów. Często nie pojedyncze związki, lecz ich mieszaniny o określonym składzie są aktywne semiochemicznie. Zmienność składu lotnych roślinnych substancji semiochemiczych można oceniać metodami chemometrycznymi w celu znajdywania składników istotnych w ekologicznej interakcji. Przeprowadzono pełną analizę chemometryczną danych literaturowych dotyczących zmian składu terpenów i seskwiterpenów z igieł sosny Pinus caribaea w odniesieniu do żerowania mrówek Atta laevigata. Do klasyfikacji danych zastosowano metodę analizy wiązkowej i metodę głównych składników. Dla opisu ponad 90% zmienności składu wystarczyło zastosować dwa faktory opisujące dane dotyczące drzew defoliowanych i niedefoliowanych. Metodą analizy chemometrycznej z ładunków faktorów zidentyfikowano związki chemiczne istotne w oddziaływaniach ekologicznych.

Opis:
The effect of the amount of pine needle oil on the properties of rigid polyurethane (RPUF) foams was investigated. The influence of pine needle oil content on the cellular morphology, physical, mechanical, and antibacterial properties of RPUF was evaluated. The addition of pine needle oil had decreased the dynamic viscosity and processing times of polyurethane (PUR) systems. It was found that the foams containing 5 wt % of pine needle oil had better mechanical properties, e.g. compressive strength, flexural strength, and impact strength. RPUF containing the highest concentration of pine needle oil, such as 15 wt %, possessed improved antibacterial activity against E. coli and S. aureus. This study confirmed that the use of pine needle oil is an effective approach to the production of RPUFs with antibacterial activity.
Zbadano wpływ dodatku olejku sosnowego na właściwości użytkowe sztywnych pianek poliuretanowych (RPUF): strukturę, właściwości fizyczne, mechaniczne i antybakteryjne. Układy poliuretanowe (PUR) modyfikowane dodatkiem olejku sosnowego charakteryzowały się mniejszą lepkością dynamiczną oraz krótszymi czasami syntezy niż układy bez dodatku. Najlepsze właściwości mechaniczne, w tym m.in. wytrzymałość na ściskanie, zginanie trójpunktowe i udarność, wykazywała pianka poliuretanowa zawierająca 5% mas. olejku sosnowego. Najlepszymi właściwościami antybakteryjnymi (względem E. coli oraz S. aureus) odznaczała się pianka zawierająca 15% mas. olejku sosnowego. Stwierdzono, że modyfikacja układów poliuretanowych dodatkiem olejku sosnowego umożliwia otrzymanie RPUFs o właściwościach antybakteryjnych.

Opis:
The basic aim of the work was to widen the knowledge about variation of Pinus mugo in the Karkonosze (Giant) Mountains and verification of provenance of several, probably planted populations on that basis. Seven populations were sampled, four on hardly accessible precipices of glacial cirques as natural, and three on the topical, mostly plane or only slightly in clined parts of the mountains as potentially alien ones. The variation of the needles was biometrically analyzed in respect of 23 morphological and anatomical characters. Measurement data were subject of multivariate statistical analyses. Results call attention on rather continuous variability of P. mugo in the Karkonosze Mts. The differences among samples were found as relatively low and no direct connections have been detected between variation and provenance from precipices versus plane sites.

Modern forestry management should be based on the principle of sustainability.In order to preserve habitat productivity, the amount of nutrients removed from the environment along with forestry products must be taken into consideration. This study shows the exact concentrations of chemical elements in different tree parts of Scots pine, growing on poor soils in north-western Poland. The observedvalues were compared to the values found in literature. In addition, the relationship between the concentrations of elements and stem diameter or stand density was researched. The highest concentration of chemical elements was observed in the needles (C, N, P, K, Mg, S, Mn, Na, Fe) and the lowest (C, N, P, S, Cu, Na, Ni, Pb, Zn, Fe) in the stem wood. Most of the macronutrients (P, K, Ca, Mg and S) reached optimal values, with the exception of N showing a deficiency, especially in the needles. The relationship between the content of elements and DBH or stand density was rather weak, and in both cases, negative.

Opis:
Pinus eldarica has been introduced to Iran from more than 800 years ago. Some individuals of this pine have altered both in shape and growth rate in northeastern of Iran, and generated two distinct morphotypes which are called Conical-shaped and Ball-shaped pines. This study was conducted to discriminate these morphotypes using macromorphological and anatomical characteristics. Results of macromorphological analysis showed significant differences both with univariate and multivariate analysis and consequently two new morphotypes were clearly separated from Mondell pine individuals. Furthermore, anatomical differences observed in Conical-shaped pine in comparison with two other pines, from some valuable taxonomical point of view traits such as cross-section form of needle, number of stomata per area, number and position of resin ducts etc. Furthermore, the existent difference in traits like cuticle thickness, stomata density, needle perimeter and length, state increasing the adaptation potential to aridity in Conical-shaped pine in comparison with two others. The differences of two new morphotypes demonstrate that they are new variants of Mondell pine and it is need to be used molecular markers and phylogenic studies for specifying the cause of these morphological and anatomical differences.

Opis:
The photochemical activity of photosystem II (PSII) was measured by chlorophyll a fluorescence intensity of Scots pine needles, from trees growing in various forest experimental areas exposed to air and soil pollution. Fluorescence techniques was used as a no-invasive method of detection injuries of the photosynthetic apparatus. Chlorophyll fluorescence parameters such as PSII photochemical efficiency (Fv/Fm), chlorophyll fluorescence decrease ratio (Rfd) and size of the acceptor pools available to PSII (Sm) indicated seasonal changes in the activity of the photosynthetic apparatus of pine needles. Significant differences in the variable fluorescence parameter rations Fv/Fm and Rfd between the studied sites were found in middle-winter dormancy period in January and also in samples collected in August. Winter inactivation of photosynthesis results in areduction of the photochemical efficiency Fv/Fm and Rfd. Presented results demonstrate that the effect of industrial pollution on Scots pine needles is detectable by of measurements of fluorescence parameters. They showed that Scots pine trees indicated physiological adaptation to environmental pollution and this can be monitored by the fluorescence signals earlier than by other methods.

Analizowano następujące parametry fluorescencji chlorofilu a: Fv/Fm, Rfd i Sm/Fm. Stwierdzono ich sezonowazmie - nność. Istotne różnice statystyczne pomiedzy stanowiskami wzrostu badanych populacji wystąpiły dla parametru Fv/Fm i Rfd w okresie spoczynku zimowego w styczniu. Zaburzenia fotosyntezy zimą prowadzą do redukcji wydajności fotochemicznej wyrażonej stosunkiem Fv/Fm i Rfd. Uzyskane wyniki wskazują iż kondycję drzew iglastych rosnących w skażonym środowisku można ocenić przez pomiar fluorecencji chlorofilu a w igłach. Przedstawione badania wspierają hipotezę zakładającą, że sosna zwyczajna należy do drzew o wyraźnej fizjologicznej zdolności adaptacji do skażonego środowiska.

Opis:
This work was undertaken to determine lipids changes in needles of Scots pine (Pinus sylvestris L.) populations growning on polluted stands near a phosphate fertilizer factory in Luboń, and copper smelter in Głogów and in a control area in Kórnik. Needles from polluted areas had a lower content of total phospholipids than samples from the unpolluted site. Greater changes were detected in membranes of needles collected in October and January. In comparison with the control total phospholipid in needles of populations from polluted areas were 14 to 33% lower. Phosphatidylcholine (PC) phosphatidylethanolamine (PE) and phosphatidylglicerol (PG) were the dominant phospholipids. The analysis of fatty acids in phospholipid fraction showed a decrease of linoleic acid (18:2) and linolenic acid (18:3) contents. The level of polyunsaturated fatty acids in needles of three populations from polluted areas was up to 40% lower as compared with the control. Moreover, phospholipids and their fatty acids showed seasonal fluctuations. The contents of PC, PG and PE increased in autumn and in winter, during the process of cold acclimation. In July, current-year needles did not show significant differences in membrane lipid composition between the polluted areas of Scots pine populations. The results suggest that the lipid changes of needles could be associated with disturbances in phohospholipid metabolism, caused by environmental pollution.

Opis:
The main aim of this study was to describe the variation between the populations of the dwarf mountain pine Pinus mugo Turra based on the morphological and anatomical traits of their needles, and to investigate the relationship between the observed variation and environmental conditions (altitude and substrate).Two-year-old needles were collected from 180 individuals of six populations of P. mugo growing in the Tatra Mts. Two populations were classified as dense, located at 1360–1450 m altitude, and the remaining four formed loose clusters and were situated at 1500–1650 m altitude. Four of the populations are growing on granite and two on a limestone substrate. The natural variation of 10 morpho-anatomical and 3 synthetic needle traits was measured. In addition to descriptive statistics, the analyses of variance (ANOVA) with a Tukey test and principal component analysis were computed. We also estimated Pearson correlation coefficients for the examined needle traits and altitude as well as substrate. Our results indicate that the P. mugo populations differ significantly with regard to the investigated traits for which the Trzydniowiański Wierch population was the most distinct. The observed pattern of variability is largely caused by differences in stomatal traits and these features are positive correlated with altitude. Additionally, populations growing on granite have larger values for most of the examined traits compared to populations growing on limestone.
