Opis:
The results of morphological and anatomical studies on Pinus uliginosa needles from newly-discovered localities of this species in Węglowiec (Bory Dolnośląskie) are presented. The data obtained were compared to similar published material on P. uliginosa needles from its loco classico in Batorow and from the lowland locality in Węgliniec Nature Reserve, and to P. sylvestris growing nearby. In terms of needle structure, all three P. uliginosa populations were slightly different. The samples analyzed differed markedly from the sample of P. sylvestris, which contradicts the hypothesis that Scots pine has had a significant influence on the gene pool of P. uliginosa.

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 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 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.
Badano fotochemiczną aktywność fotosystemu II (PS II) igieł sosny zwyczajnej mierząc fluorescencję chlorofilu a igieł trzech populacji rosnących pod wpływem skażenia gleby i powietrza. 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:
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:
The objective of the study was to determine differences in the response of trees of three species: Pinus sylvestris, Picea abies and Pseudotsuga taxifolia to environment pollution with fluorine compounds. The amounts of free and complexed fluorine (FA) and total fluorine (FB) were determined in the needles of trees of the three species growing in a polluted area and in an area considered free from pollution. The results of this study showed that Douglas fir is a greater sensitivity to fluorine compounds than Norway spruce and Scots pine, despite its high resistance to fluorine absorption. Estimation of the degree of environment pollution on the basis visible injury and the content of fluorine compounds in needles is discussed. The results were supplemented with observations of lily of the valley (Convallaria maialis) – a plant particularly sensitive to injury by fluorine compounds.
Celem badań było określenie zróżnicowania w reakcji drzew sosny zwyczajnej, świerka pospolitego i daglezji zielonej, na wpływ związków fluoru. Analizowano zawartości fluoru wolnego i związanego kompleksowo (FA) oraz całkowitego (FB) w igłach drzew rosnących w terenie skażonym oraz uznanym za wolny od wpływu zanieczyszczeń. Wyniki tych badań wskazują na większą wrażliwość daglezji niż świerka i sosny mimo, że charakteryzuje się ona znaczną odpornością na pochłanianie fluoru. W pracy dyskutowana jest możliwość wykorzystywania obserwacji widocznych objawów uszkodzeń i pomiarów zawartości fluorków, do oceny stopnia skażenia środowiska przez związki fluoru. W badaniach dodatkowo uwzględniono konwalię – jako roślinę wskaźnikową na ten typ zanieczyszczeń.

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:
To evaluate the geographic variability of Pinus sylvestris populations seven morphological traits of needles of pines from IUFRO 1982 provenance trial have been analyzed. The studied populations originated from northern (>55°N in Russia, Sweden and Latvia), central (55-47°N in Poland, Germany, Belgium, France, Slovakia) andsouthern (<47°N in Hungary, Bosnia, Montenegro andTurkey) European ranges of Scots pine. The analyzedprovenance trial experimental areas were locatedin Kórnik (western Poland) andin Supraśl (north-eastern Poland). The greatest variation was found in needle length and number of stomata rows on the flat and convex side of a needle, whereas number of stomata per 2mmof needle length on flat and convex side of a needle was stable, with minor interpopulational variation. Biometrical analyses revealed a significant population × location interaction anda geographical pattern in interpopulational differentiation in both experimental sites, with the northern andsouthern European Scots pine groups of provenancesdiffering significantly from the group of central origin. The results obtainedare compatible with previous results of studies on provenance variability of the Scots pine from IUFRO 1982. In the light of available data, the influence of the Balkan glacial refugia of Pinus sylvestris on a present genetic diversity of this species in Europe and the reconstruction of Scots pine migration routes after the last glacial period are discussed.

Opis:
The taxonomic position of the population of tree-like, mostly polycormic individuals of pines from the Mshana peat bog in the Gorgany Mountains (East Carpathians, Ukraine) has been studied on the basis of the morphological characteristics of cones and needles, and anatomical characteristics of the needles. These features have been compared with the surrounding Pinus mugo population as well as P. uliginosa, P. mugo, P. sylvestris and P. uncinata from natural populations of the taxa. Tree-like individuals were found to have the most similar needles to P. uliginosa, but most similar cone characteristics to P. mugo. It was concluded, that the tree-like population has a relic character and can present the trace of the early migration of P. uliginosa from the West and its hybridisation with P. mugo.

The effect of two fungicides Falcon 460 EC and Gwarant 500 SC used at recommended rates and concentrations to protect seedlings in the natural regeneration of Scots pine against Lophodermium needle cast was investigated. Also, the effect of the fungicides on the status of mycorrhizae and growth of seedlings was assessed. Single or twofold application of Falcon or Gwarant to pine seedlings during the growing season may appear insufficient to provide complete protection against Lophodermium needle cast, especially when the threat of infection is higher. Falcon was found to be more effective in protecting pine seedlings against Lophodermium needle cast in comparison with Gwarant. None of the tested fungicides had a limiting effect on the formation of mycorrhizae and growth of seedlings. Both fungicides had a slight limiting effect on the formation of complex dichotomous and coralloid structures only in one−year−old pines.

Opis:
Scots pine (Pinus sylvestris L.) is one of the most widespread forest trees in the world, ranging from southern Mediterranean mountains to eastern Siberia. 30 trees of Scots pine from the Miłomłyn Forest District were analyzed in terms of 7 nuclear and 8 chloroplast microsatellite DNA loci as well as 7 morphological needle traits. Nuclear microsatellites (Simple Sequence Repeats) have proved to be useful in studying phylogeographic and gene flow patterns in conifers and are being used to infer the demographic history of tree species. A population’s genetic diversity, in fact, represents an important criterion which could be applied in planning future forest management and breeding. Additionally, many elements of Scots pine morphology, including needle traits, are subject to environmental modification. However, the adaptability of those traits remains, to some extent, under genetic control. The trees we investigated here are called Tabórz pine located in the northeast of Poland. This population is described as one of the best in Poland and even in Europe regarding bio mass production, ductility and wood quality. The aim of the study was to determine variation and genetic structure within this population. An analysis of phenotypic differentiation showed that the traits which differed the most between individuals were needle length, the number of serrations per 2 mm of needle length along the right edge and the number of stomatal rows on the convex side of the needles. In Tabórz pine, we detected 30 different genotypes with 87 alleles as well as 28 haplotypes with 30 alleles. We also revealed a slight excess of homozygotes, but the population is still in Hardy-Weinberg equilibrium. The Scots pine population from Tabórz furthermore showed a higher level of genetic diversity compared to stands from other Polish and European regions. This diversity may be the main factor impacting on the population’s wood quality and its breeding value.
