Opis:
Представленные в статье исследования были направлены на рпределение числовых данных об основных химических, физических и механичеcких свойствах древесины черного дуба происходящей из отечественных pаскопок локализованных на речной террасе Вислоки и заливной террае реки Бобр. Проведенные исследования показали, что древесина черного дуба после сушки до воздушно-сухого состояния характеризуется высокими механическими свойствами. Одним из существенных недостатков древеcины ископаемых дубов является ее повышенная склонность к десорбционным трещинам в сравнении с современной древесиной. Можно констатировать, что древесина черных дубов пригодна для использования в деревоперерабатывающей промышленности и в художественном ремесле для производства ряда очень ценных издений.
The aim of the investigations as presented in the paper was to determine the numerical data about basic chemical, physical and mechanical properties of black oak wood originating from home discoveries located on a terrace of the Wisłoka river and on the flooded terrace of the Bóbr river. The investigations have proved that the black oak wood after drying to the air-dry state is characterized by high mechanical properties. One of the significant shortcomings of the fossil oak wood is its greater susceptibility to desorption crackings as compared with the contemporary wood. One can presume that the black oak wood originating from both discovery places could be made use of in the wood processing industry and artistic craft for production of many very valuable articles.

Opis:
Results of the investigations of spatial and temporal differentiations of Apoidea in the forests of Wielkopolski National Park were presented. It was shown that the both forest floor differ with the degree of species differentiation and domination’s structure and total number of bees. In the herbaceous layer of the forests about twice as many spedes were found than in the crowns. Also the Shannon-Weaver’s indices for bees communities of the herbs layer are higher in all three investigated forest ecosystems. The curves of Apoidea numbers in tree crowns and forest floor were similar. The curves of Apoidea numbers in the deciduous forests have one peak in the first days of May. Whereas the curves of Apoidea numbers in the pine forest have multi peak course. It was proved that trees play an important role in feeding chain of bees inhabiting deciduous forests.

Opis:
Subfossil trunks of oak (Quercus robur L. and Q. petraea Lieb.) are fundamental for construction of long dendrochronological standards for southern Poland. In the last three years over 400 new oak trunks from alluvial deposits from the basins of the rivers Vistula and Odra were analysed. Most trunks came from the last 2500 years and the produced local chronologies permitted for improvement of the standard chronology POLAND2, covering the period 474 BC-I 555 AD. Subfossil oak trunks from several sites in the river Vistula basin (Grabie, Wolica, Podolsze and others) and from alluvia of the river Odra in Wrocław enabled construction of a new long chronology C_3000E, spanning the years 1795-612 BC. This chronology was absolutely dated through teleconnection with standards for southern Germany. A row of floating chronologies, dated with the radiocarbon method, was established for the older periods of Holocene. They cover the following intervals: ca. 670-400 BC, ca. 2200-1900 BC, ca. 3400-3100 BC, ca. 3800-3600 BC and ca. 6650-6150 BC. Subfossil oak chronologies constructed by the author, together with standards based on living trees, monuments of wooden architecture, and archaeological timbers from Wielkopolska (449- I 994 AD), Lower Silesia (780-1994 AD) and Małopolska (910-1997 AD) practically allow for absolute dating of oak timbers from the area of southern Poland coming from the last 4000 years.

Opis:
The aim of the studies carried out in the natural oak-hornbeam forest Tilio-Carpinetum typicum and in the degenerated form in the stage of pinetization Pinus-Lamniastrum, was to obtain and compare qualitative-quantitative structures of soil fungi communities in two different oak-hornbeam forests. This degenerated form of oak-hornbeam forest is the result of removing the natural tree population (typical oak-hornbeam forest) and re-afforesting the resultant vacant area with pines. The study plots were located in such a way that the variations of soil fungi communities were affected only by seasonal changes in the vegetation of the degenerated oak-hornbeam forest Pinus-Lamnias- trum. The soils in both study plots are typical forest grey-brown podzolic soils (Luvisols). The results of mycoiogical studies indicate significant differences between soil fungi communities in both oak-hornbeam forests, although similarities especially in species composition of 15 of the most abundant fungi species were also found. The differences are the result of changes in the floral composition of degenerated oak-hornbeam forest. In the past, when typical oak-hornbeam forest covered whole studied areas, the soil fungi communities were probably almost the same in both plots. The first change could have happened after the removal of the trees; the second, after the re-afforestation of the resulting vacant area with pines. The re-appearance of Tilio-Carpinetum typicum in its once occupied habitat causes changes in the soil fungi community in the degenerated oak-hornbeam forest.

Opis:
The results of measurements of 5780 acorns confirm that Quercus robur has acorns of langer size, as componed with acorns of Quercus petraea. Their length varied from 1.90 to 3.50 cm, with the average 2.71 cm, while in case of Q. petraea this characteristic varied from 1.60 to 3.50 cm, with the average 2.43 cm. The diameter of acorns was similar for both species. Dry mass of Q. robur acorns ranged from 1.054 to 4.937 g, on average 2.5924 g; in the case of Q. petraea it ranged from 0.835 to 4.796g, on average 1.8364 g. Taking into consideration the coefficient of variability of length and diameter, both species do not differ significantly. It ranged from 9 to 12%. In the case of dry mass the difference was larger and it was 23% and 28% for Q. robur and Q. petraea, respectively. The analysis of variance (F-test) showed, that the species taken as the source of variability influences significantly the length of acorns (in 17%) and dry mass (in 47%). Internal features determine these characteristics in 52% and 46%. F-test did not detect any dependence between oak species and the diameter of acorns.

Opis:
The paper provides information concerning the growth of pine, spruce, oak, beech and fir stands based on the research conducted by the European Forest Institute in a number of the European countries and in Poland. Noteworthy i.a. is the increase in volume increment of spruce and pine in some stands in Germany up to 250% of the values given in the yield tables. Since the early fifties of the past century beech and sessile oak in Bavaria have exhibited an increase in the height growth and volume increment. Their values markedly exceed those provided in the tables. Fir, similar to spruce, pine and beech shows the reduction in the increment and dieback in the regions under heavy industrial pollution. However in other regions under the impact of air pollution the response of pure and multispecies stands with the share of fir was positive. In Poland, a rapid decline in the dbh increment in three tree species (fir, spruce, pine) in the seventies was greater than in the sixties. In 1981−1989, fir showed a favourable growth in diameter; this positive tendency was noticed in the whole range of fir distribution in Poland, though the increment did not return to the level before its decline. The pine increment regenerated after 1990. The poorest increment was found in spruce in the eighties following its collapse in the seventies (Żywiecki and Śląski Beskid).

The genetic variance of 3−year−old seedlings participated in up to 44% to the total variance. In subsequent years, this participation was close to zero due to the decline in participation of environmental variance after outplanting. At the age of 9 years, the genetic component of the variance was noted again. Depending on the provenance the heritability for the height trait at the age of 9 to 11 oscillated from near zero (provenance from Zalesie) to 0.61 (provenance from Tronçais).

The study presents results of dendrochronological analyses of Scots pine (162 trees) and English oak (97 trees) from 13 research plots located in NE Poland. The investigations resulted in construction of local chronologies (six for oak and seven for pine), which in turn enabled to define new regional chronologies; 2_NE_PL for pine, covering the period 1738−2003 AD, and Q_NE_PL for oak, 308−year long (1696−2003 AD). The elaborated chronologies allow for absolute dating of wood and yield new data on the extent of dendrochronological signal.

The aim of this study was to verify descriptions of the morphology of the fungus responsible for powdery mildew on oak leaves of nursery seedlings and of young trees in forest stands. Infected, fully developed leaves from apical parts of stems of Quercus robur or Q. petraea were collected in two national parks and in six forest districts in Poland. The taxonomic characteres of all specimens were generally consistent with those given in keys for Microsphaera alphitoides. However, the limoniform shape of conidia, characteristic of two sites (nurseries), has not been found in available synopses. Limoniform conidia were significantly longer and wider than others. Agreat variety of forms of mycelium on leaves were observed. The mycelium appeared in three forms: (1) floccose or felted oval patches (always with yellow or brown discoloration), (2) faveolate oval patches (often with yellow or brown discoloration), and (3) felted or mealy mycelium along veins (rarely with discoloration). Mycelium without limoniform conidia appeared in all forms, while mycelium with limoniform conidia appeared only in the form of patches, always causing leaf discoloration.

Oak and lime trees constitute nearly 2/3 of an overall number of trees considered as nature monuments in Poland. Being exposed to a number of agents their health condition often is poor. The wood−decaying fungi are the major age−limiting agents for trees. This paper presents the results of studies on the presence of various fungal species on 160 oak and lime trees. The author makes an attempt to define associations of fungi causing wood decay in ancient oak and lime trees in Poland.
