| Sumario: | The pine-ectomicorrhiza symbiosis is of great ecological importance due to the microbial interaction established in mycorrhizosphere and the favorable edaphic conditions created by the decomposition of organic matter. The objective of this work was to estimate the effect of the colonization of the ectomycorrhizal fungus Laccaria laccata on the growth of Pinus greggii, as well as the abundance of microorganisms in its roots, under greenhouse conditions. It was observed that one year after sowing and 6 months after inoculation, L. laccata positively influenced the growth of P. greggii; in addition, the microbial metabolic activity (AWCD) increased, but there were no differences in the metabolic diversity index with respect to the control. In turn, a greater abundance of phosphate-solubilizing and nitrogen-fixing bacteria was found in the rhizosphere of the inoculated plants. This suggests that these organisms are favored under the conditions that induced the presence of L. laccatta. |
