Abstract

TAPIA-GONE, J. Jesús et al. Infectivity and effectiveness of arbuscular mycorrhizal fungi from saline soils on lettuce crop (Lactuca sativa). Rev. Mex. Mic [online]. 2010, vol.31, pp.69-74. ISSN 0187-3180.

Forming Fungi inoculation of Arbuscular Mycorrhiza (HFMA) in horticultural, streamlines the development and growth of plants, but have not yet been evaluated sufficiently in some crops. Reason for which evaluated the efficiency of a consortium made up of four morphospecies HFMA, isolated and propagated from five sites of saline soils of San Luis Postosi state and then propagated and inoculated in lettuce plants, identifying the species Glomus mosseae, 1,2,3,4,5 sites, and species Glomus aff. etunicatum, was identified in the sites 1,3 and 4, while the species Glomus intraradices and Paraglomus sp., at site 5. It demonstrates that the consortium of HFMA, retained their infectivity, as mycorrhizal colonization was greater than 80%, but no effect was observed for morphological variables assessed (root volume, leaf area and dry weight of foliage).

Keywords : Glomus aff. etunicatum; G. intraradices; G. mosseae; Mexico; Paraglomus sp.
