Field performance of Pinusponderosa seedlings inoculated with ectomycorrhizal fungi planted in steppe-grasslands of Andean Patagonia, Argentina

Pinus ponderosa is the most planted tree species in the ecotone area of Patagonia, Argentina, subjected to water stress and a Mediterranean climate. Ectomycorrhizal (EM) fungi form obligate mutually beneficial associations with ponderosa pine which improve plant growth and resistance to adverse cond...
