    Infectivity and effectiveness of Glomus intraradices on micropropagated plants (1994)
    Springer
    Mycorrhiza 5 (1994), S. 29-37

    Notes: Abstract Colonization by Glomus intraradices takes place very early within the root system of micropropagated plantlets of strawberry (var. avanta, elsanta), raspberry (var. himboqueen, Zeva I), and hortensia (var. leuchtfeuer). The arbuscular mycorrhizal fungus (AMF) did not colonize roots of the different hosts to the same extent, and considerable differences were observed between the varieties. The results reported here confirm that endomycorrhizal root colonization is affected by the host-fungus combination. The effects ranged from mutualistic (hortensia), through neutral (strawberry var. avanta, raspberry var. Zeva I) to negative (raspberry var. himboqueen and strawberry var. elsanta). Non-mycorrhized (control) plants of strawberry produced more runners than mycorrhized plants under controlled growth conditions (phytotron). Transfer of the potted plants to the field resulted in drastic alterations in overall growth and development within 4 weeks. Mycorrhized plants became healthy, and mycorrhized strawberry plants produced many stout runners. The number of the runners and their biomass were almost the same (var. avanta) and treated plants produced even more runners than the controls (var. elsanta). The authors have demonstrated the need to determine the specific effects of each species of AMF on individual prospective host plants prior to their utilization in the micropagation of plantlets.

    Identification of ergosterol in vesicular-arbuscular mycorrhizae (1992)
    Springer
    Biology and fertility of soils 13 (1992), S. 229-234 
    Details
    ISSN: 1432-0789
    Keywords: Vesicular-arbuscular mycorrhiza ; Glomus intraradices ; Ergosterol ; Fungal biomass ; High performance liquid chromatography ; Gas chromatography-mass spectrometry

    Notes: Summary Ergosta-5,7,22-tri-3-enol (ergosterol) was identified by gas chromatography-mass spectrometry in roots of berseem (Trifolium alexandrinum L., cv. Landsorte) and sweet corn (Zea mays L., cv. Honeycomb-F1) infected with the vesicular-arbuscular mycorrhizal (VAM) fungus Glomus intraradices. The fungal-derived compound ergosterol was determined quantitatively in root extracts using reverse-phase high performance liquid chromatography. The concentrations of ergosterol in VAM-infected roots reached 72 μ g-1 dry material in berseem and 52 μ g-1 in sweet corn after 80 days of growth, whereas concentrations in non-infected roots remained below 8 μ g-1 dry weight. Additionally, phytosterols such as β-sitosterol, campesterol, and stigmasterol were detected in both infected and non-infected roots. Ergosterol, as a characteristic fungal substance, is proposed as an indicator of fungal biomass in the early stages of VAM infection.
