Amélioration de la technique d'enrobage de graines d'espèces endémiques avec des spores de champignons mycorhiziens pour la revégétalisation de sites miniers par hydroseeding

Abstract : In order to make easier the reestablishment of New-Caledonia endemic species on degraded soils by Nickel mining exploitations when topsoil use is impossible, the use of mycorrhizal symbiosis seems to be a good opportunity. Indeed, those micro-organisms provide plants with the ability to resist to water and metallic stresses. To ensure plants mycorhizis from their germination after hydroseeding, so for better performance in revegetation, we tested a mycorrhizal seed coating technic which appears to be the best with Alginate at 12,5g/L in distilled water which pH is taken to 7,5 containing mycorrhizal fungi spores. If this technic leads to the half the AMF spores germination, it permitted 40% of roots mycorhization, a rate barely reached by classic inoculation with double quantity of inoculant. By the way, this coating can also be stored once dry without mitigating these proprieties.
