Bioprotección de Plukenetia Volubilis L. con el hongo Trichoderma sp para reducir los daños de Meloidogyne incognita bajo condiciones de vivero

Abstract

El uso de tecnologías limpias como son los productos orgánicos, tiene gran repercusión en la mitigación del uso excesivo de productos sintéticos, contribuyendo en la conservación de la fauna microbiana. Los hongos endófitos (Trichoderma sp) son organismos simbiontes mutualistas que actúan de forma benéfica dentro de los tejidos de la mayoría de plantas, entre ellas el cultivo de sacha inchi, radicando así su gran importancia nutraceútica en los contenidos de omegas 3,6 y 9 que esta produce. El objetivo de este trabajo de investigación fue caracterizar la mejor cepa de Trichoderma sp por su capacidad de bioprotección en sacha inchi frente al ataque de Meloidogyne incognita bajo condiciones controladas. Se utilizó el Diseño Completamente al Azar (DCA) con 16 tratamientos (15 cepas de Trichoderma + 1 control) y 3 repeticiones. Para determinar el efecto de bioprotección entre estos dos organismos, se inoculó 1 000 huevos a cada plántula de sacha inchi que fue colonizado con cepas de Trichoderma sp durante la siembra, utilizando sustrato estéril. La altura de plantas se evaluó 5 días después de la inoculación (DDI) y las demás variables 45 DDI. Durante este proceso, se realizó un análisis de varianza y la prueba de Duncan (p<0.05) para todas las variables estudiadas; encontrando como mejor tratamiento al T3 (KMD 35) el cual contrarresto de manera eficiente en el control de Meloidogyne incognita y las demás variables estudiadas.

The use of clean technologies as in the case of producing organic products has great impact in the reduction of the use of synthetic products and contributes to the preservation of microbial fauna. The endophyte fungi (Trichoderma sp) are mutualistic symbiotic organisms that benefit the tissues of most plants, as in the case of the sacha inchi; a plant of nutraceutical importance due to its high content of omega 3, 6 and 9 fatty acids. The objective of this research work was to characterize the best strain of Trichoderma sp by its bio-protection capacity in the sacha inchi against the attack of Meloidogyne incognita under controlled conditions. The study used a completely randomized design (CRD) with 16 treatments (15 Trichoderma sp strains + 1 of control) each repeated 3 times. To determine the bio-protection effect between these two organisms, 1 000 eggs were inoculated to each sacha inchi plantula that was colonized with Trichoderma sp strains during the sowing, using a sterile substrate. The height of the plants was evaluated after 5 days after inoculated (DAI) and the other variables were measured 45 DAI. During this process, a variance analysis and the Duncan test were run (p<0.05) to all studied variables, finding that the best treatment was T3 (KMD 35) which worked efficiently in controlling Meloidogyne incognita and the other studied variables.
