Effect of arbuscular mycorrhiza in the growth, photosynthesis and foliar anatomy on young plants of Agave tequilana
The effect of vesicular arbuscular micorrhizal symbiosis (VAM) in growth, seasonal photosynthesis, and foliar anatomy was evaluated on young plants of Agave tequilana. These were established in pots and inoculated with one of two strains of VAM fungi: Glomus fasciculatum (Gf) or Glomus intraradices...

| description | The effect of vesicular arbuscular micorrhizal symbiosis (VAM) in growth, seasonal photosynthesis, and foliar anatomy was evaluated on young plants of Agave tequilana. These were established in pots and inoculated with one of two strains of VAM fungi: Glomus fasciculatum (Gf) or Glomus intraradices (Gi), and compared with control plants without inoculation. To evaluate these treatments a completely randomized experimental design was used with six replications and 18 experimental units. The physiological and morphological variables evaluated were: photosynthetic rate, number of young leaves, length and thickness of mature leaves, and percentage of root colonization by VAM fungi. The inoculation increased photosynthetic rate, which was highest in plants inoculated with the Gi strain than both those inoculated with the Gf and the control plants, and it was related with an increase in mesophyll thickness that was most noticeable in the chlorenchyma tissue. However, the variables related to growth, length and width of leaves were unaffected. |

Se evaluó el efecto de la simbiosis de hongos micorrícicos vesículo arbusculares (MVA) en el crecimiento, la fotosíntesis estacional y la anatomía foliar en plantas jóvenes de Agave tequilana. Éstas se establecieron en macetas y fueron inoculadas con una de dos cepas de hongos MVA: Glomus fasciculatum (Gf) o Glomus intraradices (Gi), para su comparación con testigos sin inoculación. Para la evaluación de estos tratamientos se usó un diseño experimental completamente al azar, con seis repeticiones, en un total de 18 unidades experimentales. Las variables fisiológicas y morfológicas evaluadas fueron: tasa de fotosíntesis, número de hojas jóvenes, longitud, ancho y grosor de hojas maduras, y porcentaje de colonización de raíces por hongos MVA. La inoculación incrementó la fotosíntesis, siendo ésta mayor en individuos tratados con la cepa Gi que con la Gf y las plantas testigo, lo cual se relacionó con un aumento en el grosor del mesófilo, que fue más notable en el clorénquima. Sin embargo, las micorrizas no afectaron las variables relacionadas con el crecimiento, la longitud y el ancho de las hojas.
