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. La simbiosis pino-hongo ectomicorrícico es de gran importancia ecológica debido a la interacción microbiana establecida en la micorrizósfera y a las condiciones edáficas favorables creadas por la descomposición de la materia orgánica. El objetivo de este trabajo fue estimar el efecto de la colonización del hongo ectomicorrícico Laccaria laccata sobre el crecimiento de Pinus greggii, así como la abundancia de microorganismos en sus raíces, en condiciones de invernadero. Se observó que, un año después de la siembra y 6 meses después de la inoculación, L. laccata mejoró el crecimiento de P. greggii; además, aumentó la actividad metabólica microbiana (AWCD), mas no se presentaron diferencias en la diversidad respecto al testigo. A su vez, se encontró mayor abundancia de bacterias solubilizadoras de fosfatos y fijadoras de nitrógeno en la rizósfera de las plantas inoculadas. Lo cual sugiere que estos organismos se ven favorecidos en las condiciones que propicia la presencia de L. laccatta.

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. |
