Poplar biomass production at phytomanagement sites is significantly enhanced by mycorrhizal inoculation
2017
Abstract Afforestation of trace element (TE)-contaminated soil, notably with fast growing trees producing large biomass has been demonstrated to be an attractive option for their bioremediation. Mycorrhizal fungi can form symbiotic associations with plants, contributing to TE tolerance and participating actively in bioremediation processes. We studied the effects of mycorrhizal inoculation on the growth of two poplar clones (Skado and I214), to large-scale. Two TE-contaminated sites of ca . 1 ha (Pierrelaye and Fresnes-sur-Escaut, France) were planted with 2200 trees, and were either inoculated with a mixed commercial inoculum or not-inoculated and allometric parameters were determined afte…
Effect of mycorrhizal inoculation on metal accumulation by poplar leaves at phytomanaged sites
2017
Abstract Phytotechnologies for the management of lands contaminated with potentially toxic elements (PTEs) are considered as gentle alternatives to conventional remediation techniques. During the last few years, phytotechnologies have progressively shifted to phytomanagement, a concept that includes the valorization of the plant biomass produced on the contaminated site. This study aimed at evaluating the mid-term effect of ecto- and endomycorrhizal inoculation on the reduction of PTE mobility in soils and foliar accumulation by two poplar clones, Skado ( Populus trichocarpa x P. maximowiczii ) and I-214 ( P. deltoides x P. nigra ), dedicated to bioenergy purposes. The effects of inoculatio…
Mécanismes cellulaires et moléculaires et ingénierie écologique des mycorhizes à arbuscules
2017
SPEIPM; La mycorhize à arbuscules (MA) est une symbiose mutualiste entre des champignons telluriques (Gloméromycètes) et 80% des plantes terrestres, dont la majorité des plantes de culture. Elle est apparue il y a environ 475 millions d’années. Ce chapitre synthétise les connaissances actuelles sur les systèmes de transport impliqués dans les échanges de nutriments (avec un accent mis sur les échanges de carbone, azote, phosphate et soufre) entre les deux partenaires, ainsi que le prélèvement de ces nutriments par le champignon depuis le sol. Le chapitre adresse également le potentiel en ingénierie écologique de la MA dans le cadre d’une agriculture agroécologique.
