Abstract
El presente estudio tuvo como objetivo evaluar el efecto de la inoculación de la bacteria endófita Gluconacetobacter diazotrophicus como promotor de crecimiento en el cultivo de Ananas comosus L. var. Roja Trujillana con el fin de contribuir al desarrollo de técnicas sostenibles aportando un manejo amigable con el medio ambiente. Para este estudio se utilizaron cinco bacterias endófitas de la colección del Laboratorio de Suelos y Foliares de la Universidad Nacional de Trujillo (LASFB), aisladas de diferentes cultivos, las cuales fueron inoculadas a una concentración de 1 x108 cel/ml. El proceso se llevó a cabo en el invernadero de la Escuela de Ingeniería Agrónoma de la Universidad Nacional de Trujillo, utilizando un diseño en Bloques Completos al Azar (BCA). Los resultados fueron analizados mediante análisis de varianza y las medias sometidas a las pruebas de Tukey, ambas al 5 % de significación, permitiendo determinar diferencias estadísticas significativas para la cepa LASFB 1574 respecto a la acumulación de materia seca aérea en comparación al testigo. No se observaron diferencias estadísticas significativas para las demás variables.
ABSTRACT The objective of this study was to evaluate the effect of inoculating the endophytic bacterium Gluconacetobacter diazotrophicus as a growth promoter in the Ananas comosus L. var. Roja Trujillana in order to contribute to the development of sustainable techniques providing a friendly management with the environment. For this study, five endophytic bacteria from the collection of the Soil and Foliar Laboratory of the National University of Trujillo (LASFB) were used, isolated from different crops, which were inoculated at a concentration of 1 x108 cel/ml. The process was carried out in the greenhouse of the School of Agronomy of the National University of Trujillo, using a Random Complete Block (BCA) design. The results were analyzed by analysis of variance and the means submitted to the Tukey test, both at 5 % significance allowing us to determine significant statistical differences for the LASFB 1574 strain with respect to the accumulation of aerial dry matter compared to the control. No significant statistical differences were observed for the other variables.
