Resumo

Se evaluó el efecto de microorganismos benéficos (MOBs) en el desarrollo del cultivo de fresa (Fragaria sp.). La investigación se realizó en tres fases. (i) Primera: en la provincia de Azuay – Ecuador, se recolectaron muestras de distintas plantas ubicadas en tres pisos altitudinales con características climatológicas diferentes. (ii) Segunda: en el laboratorio de la Universidad Nacional Agraria La Molina, en Lima – Perú, con cada muestra vegetal, se preparó la solución madre, así como medios de cultivo para MOBs, después se identificó la flora microbiana benéfica. (iii) Tercera: en la etapa de campo, se inoculó en el suelo un consorcio microbiano, con cuatro repeticiones por cada piso altitudinal; posteriormente se plantó fresa. En los medios de cultivo se constató la presencia de levaduras, Bacillus spp., Lactobacillus spp., y actinomicetos. Se comprobó que, según la procedencia, los microorganismos presentan efectos heterogéneos en el desarrollo de las plantas. Se concluye que en cada piso altitudinal existen microorganismos benéficos de acuerdo a la especie vegetal, que su inoculación en el suelo incrementa el número de hojas, así como también favorece el desarrollo longitudinal, diametral y de raíces, de las plantas de fresa.
