          Abstract

          Este trabajo consistió en propagar e identificar hongos micorrícicos arbusculares (HMA) recolectados de plantas medicinales (PM) de áreas naturales de bosques mixtos, y seleccionar consorcios micorrícicos con base en la promoción del crecimiento de vinca Catharanthus roseus (L) G. Don, planta medicinal cuyos alcaloides tienen propiedades antineoplásicas. En la primera fase experimental se recolectaron raíces y suelo rizosférico de 13 PM establecidas en campo para evaluar el porcentaje de colonización total (PCT) y cuantificar el número de esporas; además, se tomó una parte del suelo para establecer plantas trampa en invernadero durante 10 meses, y posteriormente evaluar el PCT e identificar los principales géneros de HMA. Todas las PM en su condición natural presentaron colonización micorrícica, observándose cuatro géneros de HMA (Glomus, Acaulospora, Gigaspora y Scutellospora), de los cuales Acaulospora y Glomus fueron los predominantes. En la segunda fase experimental se seleccionaron ocho consorcios con base en el PCT (> 40 %) obtenido en las plantas trampa, que correspondieron a las muestras recolectadas de Adiantum capillus-veneris L., Castilleja tenuiflora Benth., Erigeron karvinskianus DC., Pimpinella anisum L., Plantago major L., Ricinus communis L., Rubus fruticosus L. y Rumex mexicanus Meisn. Estos consorcios fueron inoculados en plántulas de C. roseus para evaluar su capacidad de estimular el crecimiento de esta especie en condiciones de invernadero. Después de 70 días, a pesar de presentar un solo género predominante (Glomus), el consorcio aislado de R. mexicanus promovió de manera más consistente el crecimiento de C. roseus (número de hojas, área foliar y peso seco foliar) en comparación con el resto de los consorcios micorrícicos.

          Translated abstract

          This study consisted on propagating and identifying arbuscular mycorrhizal fungi (AMF) collected from medicinal plants (MP) of natural areas of mixed forest (Estado de Mexico), and selecting mycorrhizal consortia based on the growth promotion of Catharanthus roseus (L) G. Don, medicinal plant whose alkaloids have antineoplasic properties. In the first experimental stage, roots and rhizospheric soil were collected from the 13 MP in which the mycorrhizal colonization percentage (MCP) and the number of spores were assessed; in addition, soil samples were used for establishing culture traps under greenhouse conditions for 10 months and thus, the main AMF genera were identified. All MP showed AMF colonization, and four fungal genera were identified (Glomus, Acaulospora, Gigaspora, and Scutellospora) from which Acaulospora and Glomus were predominant. The second experimental stage allowed the selection of eight consortia based on the MCP of trap cultures (> 40 %), that corresponded to samples collected from Adiantum capillus-veneris L., Castilleja tenuiflora Benth., Erigeron karvinskianus DC., Pimpinella anisum L., Plantago major L., Ricinus communis L., Rubus fruticosus L. and Rumex mexicanus Meisn. These consortia were inoculated to C. roseus to evaluate their capability for stimulating the plant growth under greenhouse conditions. After 70 days, in spite of presenting only one predominant AMF genus (Glomus), the consortium isolated from R. mexicanus showed more consistent effects on the growth of C. roseus (leaves number, leaf area and leaf dry weight) when compared to the remaining mycorrhizal consortia.
