Ektomycorrhiza species in a soil exchange experiment

<p>Original data comes from a project which takes or took place as part of the DFG priority program "Exploratories for large-scale and long-term functional biodiversity research". The data is stored together with descriptive metadata, in combination called a dataset, in the project repository (https://www.bexis.uni-jena.de). Species information was extracted from that original dataset. The second paragraph is part of the metadata of the original dataset.</p> <p>Die Zusammensetzung der Ektomykorrhizagesellschaft in Buchenreinbeständen kann sehr unterschiedlich sein. Die vorkommende Baumarten spielen eine wichtige Rolle, aber sie können nicht der einzige Faktor sein, sont wurde i allen Buchenreinbeständen die gleiche Ektmykorrhizagesellschaft vorkommen. Andere Faktoren wie Bodentyp, Nährstoffe, pH, Bodenfeuchte spielen wahrscheinlich auch eine große Rolle.</p>

Influence of Environmental Change on the Rooting Zone of Forest Trees: Condition of Mycorrhizae

To investigate the structural and physiological characteristics of selected mycorrhizal species in relation to nitrogen availability. To test whether the Hartig-net of mycorrhizae is affected by nitrogen. To examine the biochemical responses of mycorrhizae to nitrogen (particularly enzymes associated with nitrogen metabolism: glutamine-synthetase and glutamate-dehydrogenase). Leading Questions: Can fine-roots and mycorrhizas of forest trees act as indicators for nitrogen and acid inputs into forest stands? What are the biochemical and molecular responses of mycorrhizas to nitrogen and acid inputs (particularly enzymes associated with the nitrogen metabolism and with the plant defense response)? Are there, among selected types of mycorrhiza, differences in the biochemical and molecular responses? Are the structural characteristics of mycorrhizas, i.e. formation of Hartig net, affected by nitrogen and acid inputs?

Unters. zur Mykorrhizierung v. Waldbäumen u. zur Bodenmikrobiol. auf forstl. rekultivierten Kippenstandorten des Lausitzer und des Mitteldeutschen Braunkohlereviers - TP I: Die Mykorrhizierung von Waldbäumen auf verschieden alten Kippenstandorten

Ziel des Teilprojektes war die Erfassung der Mykorrhizaformen auf unterschiedlich alten, forstlich rekultivierten Kippenstandorten (Chronosequenz).

The Role of Root Exudates in Aluminium Tolerance of Norway Spruce

This project aims at the role of chelating organic exudates from non-mycorrhizal long-roots and ectomycorrhizal lateral roots in Al tolerance of coniferous trees. A laboratory study is performed with Norway spruce seedlings as model system. Non-mycorrhizal and ectomycorrhizal seedlings are treated with solutions in which pH and total concentrations of Al and Ca are varied. Organic root exudates are analyzed for their composition with emphasis on low-molecular weight organic acids and phenolic compounds. The composition of root exudates and the occurrence of organically complexed Al are compared with concurrent changes in element uptake, and in root and shoot morphology. Leading Questions: Do chelating organic exudates play a role in the aluminum tolerance of coniferous trees?
