Nuclear techniques to study the role of mycorrhiza in increasing food crop production

A group of consultants, whose names are listed at the end of this publication were invited by the FAO/IAEA Division to Vienna from 16-20 November 1981 to review, together with the Division's staff, the state-of-the-art regarding Vascular-arbuscular-mycorrhizal symbiosis with various food crops, to assess the useful role of the association in food crop production, and to recommend inputs that the Joint FAO/IAEA Division could make to promote research which might lead to the exploitation of VAM for increased crop production. The reports presented at the meeting covered several topics, including the ecology of the VAM fungus, mechanism of VAM infection, factors affecting the establishment of an effective symbiosis with food crops, mechanisms for enhanced nutrient availability to mycorrhizal plants, increased tolerance of mycorrhizal plants to adverse environmental conditions, inoculum production and field inoculation procedures. These reports, together with the experimental plans and recommendations made at the meeting, are embodied in this unpriced Technical Document. Separate abstracts were prepared for the various presentations at this meeting
