Título: | Comparative effects of native filamentous and arbuscular mycorrhizal fungi in the establishment of an autochthonous, leguminous shrub growing in a metal-contaminated soil |
Autor: | Carrasco Blázquez, Lucía CSIC; Azcón González de Aguilar, Rosario CSIC ORCID ; Kohler, Josef; Roldán Garrigos, Antonio CSIC ORCID ; Caravaca Ballester, María Fuensanta CSIC ORCID | Fecha de publicación: | 2011 | Editor: | Elsevier | Citación: | Science of The Total Environment 409(6): 1205-1209 (2011) | Resumen: | The aim of this study was to assess the effectiveness of inoculation with a native arbuscular mycorrhizal (AM) fungus, Glomus mosseae (Nicol. and Gerd.) Gerd. and Trappe, or a filamentous fungus, Penicillium aurantiogriseum Dierckx 1901, on the establishment of Coronilla juncea L. seedlings grown in a polluted, semiarid soil. For that, root and shoot biomass, nutrient uptake, mycorrhizal colonisation and nitrate reductase (NR) and phosphatase activities were analysed. Six months after planting, the shoot biomass of C. juncea was increased only by the inoculation with G. mosseae (by about 62% compared with non-mycorrhizal plants). The shoot NR and root acid phosphatase activities were increased more by inoculation with G. mosseae than with P. aurantiogriseum inoculation. The root NR activity and foliar nutrient contents were increased only by the inoculation with the AM fungus. The root Zn and Cu decreased with the AM fungus. In conclusion, the autochthonous AM fungus was an effective inoculant with regard to stimulating growth and alleviating heavy metal toxicity for plants growing on a soil contaminated by multiple heavy metals. Inoculation with an autochthonous, filamentous fungus does not seem to be a good strategy for phytoremediation of such problematic sites. | Versión del editor: | https://doi.org/10.1016/j.scitotenv.2010.12.019 | URI: | http://hdl.handle.net/10261/278446 | DOI: | 10.1016/j.scitotenv.2010.12.019 | ISSN: | 0048-9697 |
