The effect of root colonization by Glomus mosseae on the qualitative and quantitative pattern of essential oils (EO) was determined in three oregano genotypes (Origanum sp.). To exclude a simple P-mediated effect through mycorrhization the effect of P application to plants on the EO accumulation was also tested. In two genotypes the leaf biomass was(More)
In some medicinal plants a specific plant-fungus association, known as arbuscular mycorrhizal (AM) symbiosis, increases the levels of secondary plant metabolites and/or plant growth. In this study, the effects of three different AM treatments on biomass and sesquiterpenic acid concentrations in two IN VITRO propagated genotypes of valerian ( VALERIANA(More)
Red clover, known for its estrogenic activity due to its isoflavones content (biochanin A, genistein, daidzein and formononetin), was inoculated with the arbuscular mycorrhizal fungus Glomus mosseae. Once the symbiotic fungus was well established, plants were harvested and we determined the root and shoot dry weight as well as the P-content. In roots and(More)
The total phenolic and flavonoid contents and 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reduction antioxidant power (FRAP) antioxidant capacities of 19 accessions of Salvia officinalis from the sage collection of the genebank in Gatersleben (Germany) were evaluated. The major phenolic compounds of sage, that is, rosmarinic acid, caffeic acid,(More)
The major effects of arbuscular mycorrhizal fungi (AMF) colonization on plant growth, monoterpenoids and coumarins were determined in two genotypes of angelica (Angelica archangelica L., Apiaceae). Genetically uniform experimental plants were used, which was achieved by in vitro propagation of two genotypes (individual plants). The effects of Glomus mosseae(More)
A novel oxygen-based microplate assay for studying fungal activity is described. Fungal activity results in a change of oxygen concentration in CVC-96 plates and thus produces a signal that enables continuous monitoring of fungal activity. In this study the oxygen consumption was different for three tested fungi, Fusarium oxysporum f. sp. lycopersici,(More)
