Anpassung antioxidativer Systeme an Licht und Temperatur:
(2001-05-21)Unfavourable environmental conditions can cause oxidative stress in aerobic organisms. The acclimation of the antioxidative system in beech (Fagus sylvatica) and spotted nettle (Coleus ... -
Assembly of root-associated fungi in different soil layers and nitrogen uptake by ectomycorrhizae in temperate forests
(2021-07-30)Fungi are a remarkably highly diverse group of organisms on Earth, playing a pivotal role in ecosystem functioning. Belowground, they act as decomposers, pathogens or symbionts. Members of these functional categories are ... -
Communication between mycorrhizal fungi and poplar
(2015-03-18)Volatile organic compounds (VOCs) have multiple functions in the atmosphere and biosphere. VOCs are involved in above- and belowground biotic interactions. For example, VOCs released by microbes have the potential to ... -
Community structure of Arbuscular Mycorrhizal Fungi in temperate grassland and tropical land-use systems
(2015-08-31)Most plants in temperate and tropical regions form symbiotic association with mycorrhizal fungi. Studies on mutualistic association of mycorrhiza focus mainly on temperate regions of the world, whereas little information ... -
Correlation between anatomical/chemical wood properties and genetic markers as a means of wood certification
(2008-06-18)Southeast Asian forests have high species diversity. Of the floral community, Dipterocarpaceae (dipterocarps) are the most well known. This tree family is extremely rich with more than 500 ... -
Diversity and function of root-associated fungal communities in relation to nitrogen nutrition in temperate forests
(2019-01-29)Ectomycorrhizal fungi form symbiotic association with roots of a variety of plant species. They provide plants with nutrients in exchange of photosynthetic carbohydrates. In natural ecosystems, plants form associations not ... -
Drought stress response of tetraploid hybrid aspen (Populus tremula L. x P. tremuloides Michx.) of protoplast fusion experiments)
(2016-05-17)Poplar (Populus) varieties that are planted in short rotation coppice are supposed to show high biomass production, the ability to propagate via stem cuttings but also drought tolerance because drought is a very important ... -
Ecophysiological field studies of phosphorus nutrition of beech (Fagus sylvatica)
(2021-10-19)Phosphorus (P) is an essential element for plant nutrition because it is required for many essential biomolecules such as nucleotides, membrane lipids and ATP. Plants take up P as inorganic phosphate (Pi) from soil solutions. ... -
Einfluss der Kreuzungsumgebung auf die Stressresistenz der Nachkommen von Fichte (<i>Picea abies L. [Karst.]</i>) und <i>Arabidopsis thaliana</i> (L.) Heynh.
(2006-01-06)Norway spruce (Picea abies L. [Karst.]) is one of the most planted conifer tree in Europe and has a high economic significance. Nowadays climatic situation is changing rapidly ... -
FTIR-ATR spectroscopic and FTIR-FPA microscopic investigations on panel board production processes using Grand fir (Abies grandis (Douglas ex D. Don) Lindl.) and European beech (Fagus sylvatica L.)
(2008-06-17)Global warming and climate change affect the composition of German forests and require the reconstruction of domestic forest stands. As a consequence, long-term goals of forestry are the ... -
Influence of mycorrhiza on nutrient physiology of trees in mixed and mono-specific stands along climatic and land use gradients
(2022-05-25)Global change drivers such as climate change, land-use change, anthropogenic N deposition, deteriorating P nutrition and other calamities jeopardize temperate forest ecosystem functions. Essential components for the ... -
Kohlenstoff- und Stickstofftransport in temperaten Laubbäumen und ihren Mykorrhizen
(2016-05-02)In the present work was shown that Transfer of Carbon and Nitrogen was detectable from leaves to associated mycorrhizas in different broadleaf tree species. For that results of different field and laborary Experiments with ... -
Modification of lipid biosynthesis in Populus x canescens and characterization of transgenic lines
(2021-04-30)Lipid-derived hydrocarbons have many important tasks in land plants. They prevent uncontrolled water loss as constituents of the hydrophobic properties of the cuticula. Another important task of lipid-derived hydrocarbons ... -
Mykorrhizafunktion bei der Konkurrenz um Stickstoff in Kalkbuchenwäldern
(2014-04-16)Beech (Fagus sylvatica L.) is a very important tree species in Central Europe due to its economical value and ecological services. Beech forests are often growing on soils, where nitrogen is the growth limiting factor. ... -
Physiological, morphological and molecular acclimation of Populus spp. to high salinity
(2022-03-25)Salinization of terrestrial land is a global environmental problem, causing loss in soil fertility. Cultivation of salt tolerant species counteracts soil degradation and ensures productive utilization of salt-affected ... -
Wood anatomy and cytokinin-related responses in poplar (Populus sp.) under environmental stress
(2018-02-09)Woody plants like poplar are of great importance as a second generation bioenergy crop. However, wood formation is dynamic and strongly affected by exogenous factors such as drought or seasonality, and endogenous factors. ... -
Wood Quality, Carbon and Nitrogen Partitioning, and Gene Expression Profiling in <i>Populus</i> Exposed to Free Air CO<sub>2</sub> Enrichment (FACE) and N-fertilization
(2006-02-14)Atmospheric CO2 concentrations ([CO2]) are continuously rising since the beginning of the industrialization. At the same time, N-deposition is also increasing. The influences of ...
