Evaluación del efecto de la co-inoculacion de Rhizophagus irregularis y Paenibacillus sp. En el crecimiento de dos variedades de papa (Solanum tuberosum L.)

Abstract

In this project the effect of co-inoculation of the arbuscular mycorrhizal fungus Rhizophagus irregularis (MUCL41833) and the bacterial strain Panibacillus sp (R47065) was tested in 2 in-vitro produced potato cultivars. For this purpose we conducted a pot test consisting of a randomized complete block design with 4 treatments consisting in the single inoculations of R. irregularis, Paenibacillus sp and their combination and a non-inoculated control. Each treatment had 10 replicates for a total of 40 plants of each variety. The variables measured were: plant height at 30, 60 and 90 days after planting. In addition, dry biomass, and percentage of mycorrhizal colonization was assessed in treatments. The results obtained were favorable in most of these variables, differences between treatments in which microorganisms were used compared to the control.
