Opis:
Oak acorns used to be an important human food, up until recent times. The major factor inhibiting their use in modern nutrition is their high tannin content. Polish oak trees were screened in order to find out whether there are any major geographical or interspecific differences in tannin and total phenolic contents in acorns, which might help us to establish further directions in the search for low-tannin individuals. We studied the level of phenolic compounds using the standard Polish and European Pharmacopoeia method, with Folin-Ciocalteu reagent and hide powder. Altogether 49 acorn samples of Quercus robur, 13 of Q. petraea, 1 of Q. pubescens (all native) and 12 of Q. rubra (introduced) were collected in different regions of Poland. The amount of investigated phenolics in Q. robur and Q. petraea acorns was similar, and tannins constituted the main component. The Q. pubescens sample was distinguished by the lowest tannin and total phenolic content and a relatively high amount of non-tannin phenolics. Q. rubra had a slightly lower tannin content than Q. robur and Q. petraea acorns, but the level of other phenolics was much higher. The results for Q. robur suggest geographical variability of phenolic content as well as a relationship between the phytochemical and biometric parameters of oak acorns.

Opis:
Oaks have often been depicted in scientific and popular literature primarily for their size, as well as cultural and historical value. Such studies usually concerned the most impressive specimens on a national scale. However, often there is little data on the largest specimens on a local scale. The study carried out between 2020-2021 in Gryfino County was an attempt to fill this gap. The study was conducted on a group of trees that are thickest in terms of diameter at breast height. The analysis included a detailed description of dendrological parameters and an assessment of health according to the scales used in modern dendrology. Information from historical sources was also taken into account.

Opis:
Oak gall−nuts are pathological excrescences on the leaves of oaks (in Poland: Quercus robur L. and Q. petraea Liebl.) created by the Cynips quercusfolii L. The potential medical use of these non−wood forest products should be taken under consideration because of widespread use in folk medicine, but also because of the presence of gall−nuts of Middle Eastern oak species Quercus infectoria in the current Farmakopea… [2017]. The aim of this study was the preliminary analyzes of Quercus robur L. galls in the context of the diversity of the raw material and its possible consequences for the variability in tannin content, and therefore for the therapeutic value. The galls were collected in September 2018 from five living trees forming compact mid−field tree plantation in Podkarpackie Region (SE Poland). To determine the tannin content, hide powder method was used, while mass spectrometry was used for determining the identity of the raw material. The tannin content was found to be between 10.02 ±0.2% and 15.47 ±0.07%. There were no statistical differences between the tannin content of four weight groups of tested gall−nuts. The analysis of mass spectra showed the presence of gallic acid and tannin disintegration products. The results indicate that the tannin content in domestic oak galls is lower than in Quercus infectoria ones, for which less than 20% is required, however Polish galls are still the richest native tannin raw material. It was not proved that the content of tannins in oak galls was influenced by their size. A large variation in tannin content depending on the sample suggests that it might be possible to identify i.e. forest sites or climatic zones, where the obtained gall−nuts will be characterized by the high tannin content.

Opis:
Distribution of Turkish Quercus L. has a crucial value since Turkey is a transition place between Europe and Asia and located at the meeting point of three phytogeographical regions. To compare the diversity of species and to find the distribution patterns of oaks, species richness of the most current distributions were studied. Relationships of phytogeographical regions and presence of the Anatolian Diagonal relevant to oak distributions were also investigated. Analyses were performed on Davis'grid square system. The highest richness of Quercus species were found at north-western Turkey which were located in the meeting place of Asia and Europe. The lowest richness scores were found at eastern and south-eastern Anatolia. Moreover, latitude, longitude and altitude histograms showed a correlation with species richness. However, the presence of Anatolian Diagonal is partially supported.

Opis:
The article presents the results of inoculation of beech and oak stumps with a biological preparation of oyster fungus (Pleurotus ostreatus) mycelium. The inoculum was grown on a sawdust substrate at Warsaw University of Life Sciences Department of Mycology and Forest Phytopathology. The experiment was set up at the Forest Experimental Station in Rogów. Stumps were inoculated: i) immediately after tree felling or ii) at approximately 5 and 12 months after felling. A total of 60 beech stumps and 50 oak stumps were inoculated in the years 2002– 2004. The infected stumps were then inspected for the presence of the mycelium and fruiting bodies of P. ostreatus. The presence of fruiting bodies of other wood-decaying fungi was also noted. The extent of rotting was determined macroscopically, with the causal agent being confirmed on the basis of isolation and identification of mycelium from fragments of colonized wood obtained from rooted-out stumps. Oyster fungus mycelium was found to colonise beech stumps much more effectively than oak stumps. Stumps inoculated immediately after, or five months after felling were more effectively colonized by the mycelium than those inoculated after one year.
Zbadano możliwości wykorzystania boczniaka ostrygowatego (Pleurotus ostreatus) do szczepienia pniakow bukowych i dębowych w celu ograniczania bazy pokarmowej opieniek (Armillaria spp.). Biopreparat na podłożu trocinowym przygotowano w Zakładzie Mikologii i Fitopatologii Leśnej SGGW w Warszawie. Doświadczenie założono na 5 powierzchniach, na siedlisku LMśw, w Nadleśnictwie Rogow. Na wszystkich powierzchniach przed założeniem doświadczenia obserwowano występowanie objawów opieńkowej zgnilizny korzeni. Inokulowano pniaki powstałe zaraz po ścięciu drzew oraz ok. 5- i 12-miesięczne. W sumie, w latach 2002– 2004, zaszczepiono 60 pniaków bukowych i 50 dębowych. Na zainfekowanych pniakach oceniano występowanie grzybni i owocników boczniaka ostrygowatego oraz obecność innych gatunków grzybów wielkoowocnikowych. Makroskopowo określano zasięg widocznej zgnilizny i potwierdzano sprawcę (Pleurotus ostreatus) poprzez izolację i identyfikację grzybni z fragmentów drewna wykarczowanych trzech pniaków bukowych i trzech dębowych. Stwierdzono, że grzybnia boczniaka ostrygowatego znacznie skuteczniej kolonizowała pniaki bukowe niż dębowe. Pniaki powstałe zaraz po ścięciu drzewa oraz 5-miesięczne były efektywniej zasiedlane przez grzybnię boczniaka niż pniaki inokulowane po roku od momentu ich powstania. W trakcie trwania doświadczenia na szczepionych pniakach bukowych odnotowano owocniki 19 gatunków grzybów wielkoowocnikowych, a na pniakach dębowych 16 gatunków. Pniaki bukowe najliczniej były kolonizowane przez Bjerkandera adusta i Trametes versicolor, natomiast pniaki dębowe przez Stereum hirsutum.

Opis:
Erysiphe alphitoides causes the most common disease of assimilation apparatus of oaks of different age. It is believed that the pathogen overwinters in buds of the host plant or in the cracks of the bark. The aim of the study was to search for the presence of E. alphitoides in buds, leaves, and wood of sessile oak shoots using molecular techniques. Two hypotheses have been tested: (i) oaks are infected by E. alphitoides, and (ii) the pathogen overwinters in the host plant buds. The samples used in the study were collected form sessile oak trees (Miradz Forest District; 52°41'23.197'N, 18°25'33.942'E) in 2017, and consisted of dormant buds (collected in May), young leaves (collected in June), leaves with visible symptoms of the disease (collected in August), shoot with sip and surface layers of wood (collected in December). Additional part of buds was collected in May 2018. The PCR reaction was carried out with primers specific for E. alphitoides and E. hypophylla. For species identification Sanger method was used. The resulting sequences were compared using BLAST algorithm with reference sequences deposited in the NCBI database. Sequences from isolates obtained from leaves showed 97−99% similarity to the reference sequence of E. alphitoides. Pathogen did not occur in the superficial layers of shoots and buds. As some studies show, at very low temperatures (below –20°C), the mycelium of the pathogen dies, therefore further study should be undertaken on wintering of the pathogen causing the powdery mildew disease on oaks. It also should be examined whether the pathogen overwinters in the form of bagnial spores produced in chasmothecia overwintering on leaves, in the leaf buds, or in bark cracks, and whether the wintering site of the pathogen is related to the age of trees and or to the stands where the trees grow.

Opis:
The corridor method of oak (Quercus sp) cultivation is an old, forgotten silvicultural method. It was developed around the turn of the 19th and 20th century on the south-eastern borders of Poland (Podole, Wołyń) and Russia and made use of other species such as hornbeam, linden and birch as a cover for oak, which is a tree species sensitive to frosts. The nowadays recurring phenomenon of oak disease initiated a search for silvicultural alternatives and thus the usefulness of reviving the corridor method for oak regeneration was investigated by examining existing tree stands established in this way. Our research plots were located in five young stands and two in mature as well as old stands. In the stands of the 2nd and 3rd age classes, the density of oaks was observed to be 1500 - 3500 /ha, which accounted for 30-50%. The density of oak in old stands (7th age class) was similar to model-predicted values. Furthermore, the corridor method gave very good production results as exemplified by the oak stands growing on the fresh broadleaved site, which had a very high stand quality index. In addition, the species composition was observed to diversify throughout these oak stands’ development, thus supporting arguments for the conservation and preservation of oak-hornbeam forests. To summarise, the prerequisites for the success of the corridor method are systematic cuts of young stands (forest cultures and thickets) to inhibit the growth of accompanying undesired species and limiting the number of grazing animals.

Opis:
Climatic parameters are the main environmental factors affecting tree growth. The main aim of the presented study was to determine whether different oak species growing under contrasting environmental conditions show different sensitivity to climatic parameters. Four oak stands with Quercus robur, Quercus petraea, Quercus polycarpa and Quercus dalechampii growing in the same area were evaluated. Standard dendrochronological methods were used for sample preparation, ring width measurements, cross-dating, chronology development, and the assessment of growth-climate response patterns. Although the species grew under different environmental conditions, their local tree-ring chronologies are highly correlated. The radial growth responses to climatic parameters differ slightly, but the response depends more on local site conditions than on the oak species. At the same time, the strongest correlations between radial growth and climatic parameters were identical among species and sites. The amount of water available in the soil was the main climate-dependent factor limiting radial growth. Approximately since the 1990s, the distribution of rainfalls within the growing season has changed at the expense of spring precipitation. The significance of relative soil moisture content during spring for oak growth increased and the significance of summer values decreased.

This study examines the effect of flood on oak stands in the Wołów Forest Division by assessing the loss of leaf area due to insect feeding as determined in laboratory analyses of samples collected from standing trees. We compared stands, in which water stagnated for at least one month and stands with no water stagnation. It was found that the mean damage to the carbon assimilating organs of stands with stagnating water was lowered by approximately 6% compared to stands that were not affected by flood. Thus, no definite effect of flood contributing to losses of carbon assimilating organs in oak trees could be shown.

Opis:
The rate of oak decline has greatly accelerated in recent years. It has been reported that in October 2005, the amount of standing dead trees in oak stands of 14 Forest District Administrations situated within the Regional Directorate of State Forests in Warsaw exceeded 70,000 m3 and an area of 103 hectares was selected where sanitary fellings need to be applied. The restocking of cut areas in the thinned stands with substitutional species was proposed. Besides, the paper presents a conception of oak regeneration by planting trees in wider spacing, under the shelter of pioneer species (mainly birch), using the tending species (i. a. hornbeam).

Opis:
Oak decline is insufficiently described problem. Declining oaks are in various age and the most commonly observed symptoms of the disease include growth inhibition and buds mortality. The dieback occurs periodically, mainly because of the impact of abiotic factors (drought, frost and the lowering of the groundwater level). In this complex phenomenon the biological factors, including numerous species of Chromista (Chromalveolata) and fungi play important role as well. The list of pathogens responsible for the dieback includes numerous species of Pythium and Phytophthora, as well as Biscogniauxia, Discula, Pleurophoma, Botryosphaeria and Diplodia. Among other organisms responsible for the oak decline are fungi belonging to Fusarium species. The aim of this study was to investigate the species composition of pathogens colonizing the dying oak buds including undeveloped or dying shoots obtained from Łomża, Rudka and Czarna Białostocka forest districts (eastern Poland). Sampling of symptomatic shoots of Quercus robur L. was performed in 2013, respecting different parts of tree crowns (top, central and bottom). Mycological material for analysis included mycelium growing on dying shoots after incubation in a chamber and tissue collected from symptomatic shoots and placed on PDA medium. For selected isolates of fungi the identification was confirmed by the PCR analysis using ITS1 and ITS4 primers. Among analyzed fungi Fusarium spp., Alternaria alternata, Cladosporium cladosporioides, Botryosphaeria quercuum and /em>Coniothyrium spp. required special attention. The Fusarium spp. group of fungi dominated with an average frequency of 32%. The molecular analysis revealed the presence of several species including Fusarium avenaceum, Cladosporium cladosporioides, Lophiostoma corticola and Nectria mauritiicola.

The paper presents the state and conditions of oak natural regeneration in the „Białowieża Primeval Forest” Promotional Forest Complex. It has been stated that under natural conditions oak appears in all forest types but it infrequently grows into a stand. With the recent expansion of hornbeam, it is difficult for oak effectively to regenerate. It has been confirmed in this study that the shelterwood cutting system (leaving some trees to dye naturally) is the most efficient method of natural regeneration of oak in the Białowieża stands.
