Abstract We present BeechCOSTe52 ; a database of European beech ( Fagus sylvatica ) phenotypic measurements for several traits related to fitness measured in genetic trials planted across Europe. The dataset was compiled and harmonized during the COST-Action E52 (2006–2010), subsequently cross-validated ensure consistency measurement data among provenances. Phenotypic (height, diameter at breast height, basal diameter, mortality, phenology spring bud burst autumn–leaf discoloration) were...
Secondary metabolites are ubiquitous substances occurring naturally in trees and microorganisms. They produced various metabolic pathways which determine their structure biochemical proprieties. However, the biological functions of many secondary remain undetermined. Usually, amounts by under natural conditions limited, makes mass production difficult not cost-effective. Metabolites plants, including gymnosperm angiosperm trees, as well fungi, important biologically active used industries...
The aim of this study was to determine the efficiency methods for artificial scarification black locust seeds based on influence air and liquid nitrogen temperatures. Three populations were selected analyses: a managed tree stand, seed stand orchard. Samples 200 (4 × 50) randomly selected. Before scarification, stored at −70 °C 24 h. Nine different treatments evaluated. To calculate germination capacity dynamics germination, observations made days 3, 5, 7, 10 14 after treatment. For...
Fraxinus excelsior L. is threatened by a variety of environmental factors causing decline the species. The most important biotic negatively affecting condition F. population are fungi such as pathogen Hymenoscyphus fraxineus. Abiotic with potentially harmful effect to accumulation heavy metals and salinity in soils. Thus, aim this study was investigate impact selected abiotic stress determine which them pose threat European ash. conducted using vitro techniques based on callus seedlings...
Abstract The forests of the Sudetes Mts are among ecosystems most threatened by climate change in Poland. Abiotic factors cause threat, such as an increase average annual temperature and a clear distribution atmospheric precipitation intensity during year. aim study is to characterise process tree mortality, especially spruce, main forest-forming species region, Sudetes. analyses carried out covered 12 forest districts belonging Regional Directorate State Forests Wrocław. Calculations made...
Abstract The vertices of the k th power a directed path with n are exposed one by to selector in some random order. At any time can see graph induced that have already appeared. selector's aim is choose online maximal vertex (i.e. no outgoing edges). We give upper and lower bounds for asymptotic behaviour p , 1/( +1) where probability success under optimal algorithm. In order derive bound, we consider model which obtains extra information about edges exact asymptotics algorithm this case....
Abstract In forest production, there is an emerging tendency towards the planting of fast-growing trees as attractive, renewable energy sources. Hence, efforts were made to develop a method micropropagation by organogenesis seven clones black locust ( Robinia pseudoacacia L.) that are resistant propagation traditional vegetative methods, well one plus tree (no. 9755) at age 60, see if mother plant limitation in trees. Overall results suggest Murashige and Skoog medium supplemented with 30 g...
The aim of this study was the assessment genetic diversity and differentiation patterns European beech (Fagus sylvatica L.) populations within its natural range in Poland. These stands cover 5.2% forest area Poland, form predominant tree communities throughout Carpathians Sudety Mountains, moraine landscape Pomeranian Lake District. Varying environmental conditions have resulted a great number ecotypes which are characterized by various ecological requirements. Poland represents northeastern...
In the field of complex networks, hypergraph models have so far received significantly less attention than graphs. However, many real-life networks feature multiary relations (co-authorship, protein reactions) may therefore be modeled way better by hypergraphs. Also, a recent study Broido and Clauset suggests that power-law degree distribution is not as ubiquitous in natural systems it was thought far. They experimentally confirm majority (56% around 1000 undergone test) favor with an...
Abstract The main aim of our study was to examine the current state and analyse prospects development urban forests in city Kharkiv. Modern methods assessment forest resources ranking were used evaluation process. data from last basic inventory electronic database ‘Ukrderzhlisproekt’ Production Association are used.Conducted investigation enables assess Kharkiv, show division by land category, list species composition according stakeholders as well compare existing optimal subject age group...
European beech (Fagus sylvatica L.) is one of the most important forest tree species in Poland and it covers 5.2% area. Present genetic structure populations has been formed within last few thousand years influenced by many different factors, not only environmental (postglacial) origin, but also anthropogenic ones. In Poland, attains its north-eastern limit natural range, limited continental climate, winter temperatures, air humidity soil conditions. The growth stands outside indicates that...
We examine the evolution of best choice algorithm and probability its success from a directed path to linear order same cardinality through $k$th powers path, $1 \leq k<n$. The vertices power known length $n$ are exposed one by selector in some random permutation. At any time can see graph induced that have already come. selector's aim is choose online maximal vertex (i.e., with no outgoing edges). It shown $p_n$ for optimal satisfies $p_n = \Theta(n^{-1/(k+1)})$. also consider case when...

Abstract The analysis of chosen selected Scots Pine (Pinus sylvestris L.), populations representing different seed regions: 107 (Międzyzdroje), 305 (Woziwoda), 206 (Strzałowo), 208 (Białowieża), 504 (Bolesławiec), 606 (Józefów) were performed using 10 isoensyme markers: Gdh (E.C.1.4.1.2), Sdh-A, Sdh-B (E.C.1.1.1.25), Pgd-B (E.C.1.1.1.44), Mdh-A, Mdh-C (E.C.1.1.1.37), Got-A, Got-B, Got-C (E.C.2.6.1.1), Dia-C (E.C.1.8.1.4). There calculated following genetic parameters: allelic frequencies,...
Abstract The history and dynamics of the introduction red oak into forest plantations in Ukraine are presented. positive negative consequences this artificially introduced species characterised. anthropogenic factor a broad representation probability low natural spread out outside existing highlighted. current data on area by administrative regions, categories, types site conditions age classes indicated. possibility controlling limiting adverse invasive effects stands is pointed out. It...
We investigate a family of algorithms minimizing energetic effort in random networks computing aggregative functions. In contrast to previously considered models, our results minimize maximal over all stations instead the average usage energy. Such approach seems be much more suitable for some kinds networks, particular ad hoc radio wherein we need functioning and replacing batteries after deployment is not feasible. analyze also latency proposed energy-optimal algorithms. model network by...
Abstract Existing knowledge of the Ukrainian foresters related to historical changes and current state silver fir forests, as well on various methods restoration such forests in Carpathians were discussed. Forest cover stands this region has been diminishing last two centuries. Only period from 1947 1956, area decreased by 38.8%. Currently, these areas are crucial for forestry. Therefore, natural artificial regeneration using seeds obtained seed orchards currently used. Thus, improving...

In present study, seed disinfestation was developed extract viable zygotic embryos. Different culture media and combinations growth regulators were also tested produce seedlings elm. potential in light darkness investigated determinate exact weight gain over specific period time. results experiments can used as tool for rapid large quantities...
Abstract New challenges related to the multifunctional role of forests in consideration both natural environment and economy come into view sequentially. In current forestry practice, an important element is not only quality forest cultivations (silvicultural aspect) but also costs incurred for their production tending (economic aspect). The main purpose this article show prospect increasing positive silvicultural effects depending on method used management Scots pine stands under given site...
