In the present investigation was able to authenticate the ability to nodulate and to evaluate the frequency of nodulation efficiency of 50 isolate strains of pea nodules, collected from the departments: La Libertad, Lambayeque, Cajamarca and Lima. Which was inoculated to 1 mL of culture suspension alone (1.2x109 cel /mL) in seedlings of Pisum sativum var. Selection Junín, keeping them under conditions of relative humidity,50-70% and temperature / photoperiod, 28 °C – 24 °C / 14 h – 10 h (light-dark). At 25 days post-inoculation was obtained that 40% nodulated the host plant. To determine the frequency of nodulation efficiency, we took into account the parameters of speed of nodulation (DN in mm) and the percentage of roots nodulated (PRN%); pearson correlational analysis of the 5% significance, MANOVA and Tukey statistical DHS, allowed to establish the ranges (high, medium and low...

En la presente investigación se logró autenticar la capacidad nodulativa y evaluar la frecuencia de la eficiencia en la nodulación de 50 cultivos aislados de nódulos radiculares de arveja, colectados de los Departamentos: La Libertad, Lambayeque, Cajamarca y Lima. Para lo cual se inoculó 1mL de suspensión del cultivo aislado (1,2x109 cel / mL) en plántulas de Pisum sativum var. Selección Junín, manteniéndolas bajo condiciones de humedad relativa, 50–70% y temperatura/fotoperiodo, 28 °C - 24 °C / 14 h – 10 h (luz-oscuridad). A los 25 días post-inoculación se obtuvo que el 40% nodularon a la planta huésped. Para determinar la frecuencia en la eficiencia de nodulación, se tuvo en cuenta los parámetros de velocidad de nodulación (DN en mm) y el porcentaje de raíces noduladas (PRN%); el análisis Correlacional de Pearson al 5% de significancia, el MANOVA y el estadísti...
