Abstract: | This paper presents a hydroponic system for culturing and maintaining the VAM fungus Glomus intraradices in symbiosis with linseed (Linum usitatissimum L.) under greenhouse conditions in pure nutrient solution. It was possible to obtain large quantities of mycorrhizal host plant roots as well as extramatrical mycelium and chlamydospores free of impeding residues of solid substrate components. Starting from linseed donor plants inoculated in sand and transferred to the nutrient solution, new infections arose within the fast growing root system, hyphae spread out into the liquid and infected mycorrhiza-free receptor plants. Data for infection rates and plant growth parameters are presented. In comparsion to other culture systems for VAM fungi, the advantages of this hydroponic system are discussed and potential uses suggested. |
