SILVA, Fábio Sérgio Barbosa da; YANO-MELO, Adriana Mayumi  and  MAIA, Leonor Costa. Production and infectivity of inoculum of arbuscular mycorrhizal fungi multiplied in a substrate supplemented with Tris-HCl buffer. Braz. J. Microbiol. [online]. 2007, vol.38, n.4, pp.752-755. ISSN 1517-8382.

The effect of adding Tris-HCl buffer on production and infectivity of AMF inoculum was investigated. Sporulation of Glomus etunicatum, Acaulospora longula and Gigaspora albida was improved in solution with buffer. The infectivity of G. etunicatum increased after storage, what suggests that the inoculum of this isolate is benefited by storage.

Keywords : mycorrhiza; organic buffer; sporulation; storage.
