Morphological and physiological parameters of pepper plants inoculated with Funneliformis mosseae under hydroponic conditions and with high copper concentrations
Industrialization and agricultural activity, through the use of fertilizers and pesticides, have caused severe environmental pollution. The heavy metals incorporation is one of the problems that most concern organizations linked to environmental monitoring. Copper is an essential micronutrient for plant growth but in high concentrations it is toxic. Arbuscular mycorrhizae actively participate in the heavy metals metabolism, increasing the tolerance of plants growing in contaminated sites. The morphological and physiological responses of pepper plants inoculated with the arbuscular mycorrhizal fungus Funneliformis mosseae in increasing concentrations of copper in a hydroponic culture were evaluated. Morphological measurements (dry weight, foliar area), physiological measurements (stomatal conductance and resistance, greenness index, leaf temperature, relative conductivity of cell membranes) and biochemical (protein pattern, content of malondialdehyde) were made. The growth of the non-inoculated or inoculated pepper plants showed a decrease with the increase of the copper concentration in the medium. The plants inoculated with the arbuscular mycorrhizal fungus could withstand a higher concentration of copper than the non-inoculated ones and this concentration varied according to the parameter analyzed. In general, in mycorrhized plants an increase in the tolerance threshold to copper was observed.

La incorporación de metales pesados al medio como modo de contaminación por el uso de fertilizantes y plaguicidas es una de las problemáticas que más preocupan a las organizaciones vinculadas al monitoreo del ambiente. El cobre es un micronutriente esencial para el crecimiento vegetal, pero en elevadas concentraciones es tóxico. Las micorrizas arbusculares, participan activamente en el metabolismo de los metales pesados, aumentando la tolerancia de las plantas que crecen en sitios contaminados. Se evaluaron las respuestas morfológicas y fisiológicas de plantas de pimiento inoculadas con el hongo micorrícico arbuscular Funneliformis mosseae en concentraciones crecientes de cobre en un cultivo hidropónico. Se realizaron mediciones morfológicas (peso seco, área foliar), fisiológicas (conductancia y resistencia estomática, índice de verdor, temperatura de hoja, conductividad relativa de membranas celulares) y bioquímicas (patrón proteico, contenido de malondialdehído). Las plantas inoculadas con el hongo micorrícico arbuscular toleraron una concentración mayor de cobre que las no inoculadas y esta concentración varió según el parámetro analizado. En general, en las plantas micorrizadas se observó un aumento del umbral de tolerancia al cobre.
