| description | Physical-chemical properties of mine residues tend to prevent soil formation processes and plant growth. Nevertheless, there are plant species capable of growing in polluted environments and absorbing heavy metals. In Tlalpujahua, Michoacán, as in many mining sites, there are sites polluted with mercury because of the metal refining processes. We studied the effect of mercury in the growth medium in young conifer plants of Pinus devoniana Lindley, Pinus pseudostrobus Lindley, Pinus martinezii E. Larsen and, Juniperus deppeana Steud. Young plants of the four species were grown in media with four levels of mercury and three growth related response variables were recorded. Pinus devoniana and Pinus pseudostrobus had a reduction in growth when the concentration of mercury in the medium was 15 ppm or higher. Roots of P. devoniana had lower biomass when exposed to mercury than control plants. P. martinezii was resistant to mercury. J. deppeana had an intermediate resistance to mercury with high variation among individuals. Results indicate that J. deppeana and P. martinezii are species tolerant to mercury exposition and can be useful for reclamation of contaminated sites. |

Las propiedades fisicoquímicas de los residuos mineros tienden a inhibir los procesos de formación del suelo y el crecimiento de las plantas. Sin embargo, existen especies capaces de crecer en ambientes contaminados y absorber metales pesados. En Tlalpujahua, Michoacán, como en muchos sitios mineros, hay depósitos contaminados con mercurio a causa de las prácticas de beneficio de los metales. Se estudió el efecto de la presencia de mercurio en el sustrato, en el desempeño de plantas jóvenes de coníferas con individuos de Pinus devoniana Lindley, Pinus pseudostrobus Lindley, Pinus martinezii E. Larsen y Juniperus deppeana Steud. Las plantas de cada especie se sometieron a cinco dosis de mercurio adicionadas al sustrato y se midió la altura y se cuantificó la biomasa seca aérea y de raíz. Pinus devoniana y Pinus pseudostrobus disminuyeron su crecimiento después de ser expuestas a 15 ppm de mercurio en disolución. Las raíces de P. devoniana presentaron menor biomasa que las raíces de las plantas control. Pinus martinezii fue resistente al mercurio, mientras que J. deppeana muestra una tolerancia intermedia a la presencia de mercurio. Los resultados obtenidos indican que J. deppeana y P. martinezii son especies tolerantes al mercurio potencialmente útiles para la rehabilitación de sitios contaminados.
