Pinussylvestris, etc ; arginine; boron; nitrogen; nutrition; soil; Show all 6 Subjects
Abstract:
... Free arginine (Arg) content was observed to multiply when the level of nitrogen (N) nutrition was high, and additional fertilization with boron (B) potentiated this effect. Owing to this feature, conifers can be suggested for use as bioproducers of Arg. Concentrations of Arg in relation to N and B fertilization needed to be better understood. The effect of soil fertilization with N and B on accumu ...

Abstract:
... To determine the role of environmental and host genetic factors in shaping fungal endophyte communities we used culturing and metabarcoding techniques to quantify fungal taxa within healthy Scots pine (Pinus sylvestris) needles in a 7-y old provenance-progeny trial replicated at three sites. Both methods revealed a community of ascomycete and basidiomycete taxa dominated by the needle pathogen Lop ...

Abstract:
... The biological durability of wood is frequently determined in laboratory tests with monocultures of different decay fungi under ideal conditions for fungal growth. To avoid contamination with mould and inhibition of fungal growth, wood specimens need to be sterilized using different methods. To determine the mass loss of wood blocks during incubation, the initial total dry mass is needed but shoul ...

Abstract:
... Since the late-19th century, the Middle Volga has played a major role in the supplying grains and other agricultural products to European Russia. The study area is located in the south of sub-boreal forest in the north and in the forest-steppe in the south. Due to large seasonal differences in rainfall, agriculture in the region, especially in its southern part, strongly depends on hydroclimate va ...

Abstract:
... In this study, pine nut kernels from two grafted species: Pinus koraiensis (PK) and Pinus sylvestris var. (PKS) were roasted (130, 150, 180℃ for 10, 20, 30 min) to investigate the effect of roasting pre‐treatment on chemical components, antioxidant activity, and oxidative stability of oils prepared from kernels. Increased temperature or time was found to cause a significant increase in oil yield, ...

Abstract:
... We analyse the concentration of caesium-137 (¹³⁷Cs) in forest litter in relation to forest site conditions. The research was carried out in 2004–2019 in the Krasnogorsk district of the Bryansk region (the Russian Federation). It covered three areas corresponding to the exclusion zone, compulsory resettlement zone, and the zone of residence of the population with the right to resettlement. In all t ...

Abstract:
... Somatic embryogenesis (SE) is an important method for the vegetative propagation of trees. SE is the developmental in vitro process in which embryos are produced from somatic cells. This method can be integrated with other biotechnological techniques, genomic breeding and cryopreservation, which enables commercial-scale sapling production of selected high-yielding genotypes in wood production comb ...

Abstract:
... KEY MESSAGE: We identified the effect of microclimatic conditions on soil mite communities (Mesostigmata) during the decomposition of broadleaved and coniferous litter. The abundance, species richness, and diversity of mite communities decreased from spring to autumn regardless of litter quality and was related to changes in temperature and precipitation. CONTEXT: Litter decomposition is one of th ...
... The quantitative registration of macromycete fruiting bodies was performed during two field seasons in the pine plantations of recultivated waste dump (experimental area) and in the pine forests on zonal soils (control area). The average quantity of carpophore macromycetes on the experimental area during two years of research exceeded ones on the control area by 41%. The field season of 2020 was c ...

Abstract:
... A dendroecological study of the annual ring parameters of Scots pine (Pinus sylvestris L.) trees growing in the forest-steppe and steppe zones of Eastern Transbaikalia has been carried out. Using the methods of digital anatomy of annual rings, two (Nov and Tz) tree-ring chronologies based on four parameters (annual ring width, earlywood width, latewood width, and latewood optical density) have bee ...
... Deep planting is recommended in Nordic countries only for normal-sized container seedlings planted on mounds. Its effects on smaller-sized seedlings are poorly understood. We studied the effects of planting depth on the early field performance of small-sized silver birch (Betula pendula Roth) and Scots pine (Pinus sylvestris L.) container seedlings. Silver birch seedlings (mean height of 16 cm) we ...
... We have reviewed information on early-, late- and limit-value decomposition stages for litter of Norway spruce (Picea abies) and Scots pine (Pinus silvestris). This synthesis covers c 16 studies/papers made along a climatic gradient; range in mean annual temperature (MAT) from −1 to +7 °C and mean annual precipitation (MAP) from 425 to 1070 mm. Scots pine has an early stage dominated by carbohydra ...

Abstract:
... There is great interest in determining the effects of forest thinning as a tool to improve growth recovery from drought in different tree species and climatic conditions. However, we lack a robust framework to determine how transient are post-drought growth resilience and enhancement, and if such growth improvement involves an uncoupling with climate conditions. We used regression analysis to dete ...

Abstract:
... Given that forest stand density is an important parameter for studies of carbon, water, and energy cycles and a core indicator for forest management, it requires accurate mapping to better assess how it impacts the eco-environment. Unfortunately, the calculation of stand density has long relied on the identification of individual trees for small-scale fine mapping or on empirical methods for macro ...

Abstract:
... The Scots pine (Pinus sylvestris) plantations in central Europe are currently damaged by a large-scale infestation by bark beetles (Scolytinae). Ips acuminatus and Ips sexdentatus are among the most aggressive species causing infestations of pine trees that are currently simultaneously attacked by Ips typographus. In pine plantations prone to damage, it is therefore necessary to carry out the bark ...
... The aim of our study was to analyze the influence of the thickness of Scots pine veneers on the chosen physical and mechanical properties of plywood-like composites dedicated to flooring applications. The utilitarian goal of the research is to replace three-layer flooring requiring high production costs with flooring materials of much cheaper (lower number but thicker veneers) and less specialized ...
... Tree stems have been identified as sources of volatile organic compounds (VOCs) that play important roles in tree defence and atmospheric chemistry. Yet, we lack understanding on the magnitude and environmental drivers of stem VOC emissions in various forest ecosystems. Due to the increasing importance of extreme drought, we studied drought effects on the VOC emissions from mature Scots pine (Pinu ...

Abstract:
... The genetic structures of the four putative hybrid swarms of Pinus sylvestris × P. mugo in Slovakia were analyzed in terms of individual admixture proportions calculated via inter-primer binding site (iPBS) marker loci. This work aimed to reevaluate the hybrid swarms’ differentiation status as postulated in the previous studies at both population and genomic levels. The study confirmed intermediat ...

The paper presents a dendroclimatic analysis of tree-ring chronologies of conifers (Pinus sylvestris L., Larix sibirica Ledeb.) and deciduous (Betula pendula Roth., Populus balsamifera L.) tree species growing in natural, extrazonal landscapes of pine forest belts (ribbon forest) and natural–anthropogenic landscapes of shelter belts in the dry-steppe subzone of the south of western Siberia. The ma ...

Abstract:
... Although skid roads are more and more commonly used in Poland, they are still quite often criticised due to a certain loss of wood volume and the impact on edge trees. In this context, the results of the research described in this article can be used as a substantive contribution to discussions about strip roads. Research was carried out in a 42-year-old pine tree stand (Pinus sylvestris L.) in th ...
