Tara (Caesalpinia spinosa) ha sido cultivada durante muchos años en bosques naturales, principalmente para la recolección de sus vainas y sus semillas dado su alto valor por sus múltiples usos desde tiempos antiguos. Sin embargo, poco se conoce sobre la ecología y el estado de conservación de los bosques de tara. La simbiosis micorrítica puede desempeñar un rol central en el crecimiento temprano de esta leguminosa y constituye un componente clave para la mejora de las prácticas de manejo. El objetivo de este estudio fue describir el estado micorrítico de tara en plantaciones localizadas en Perú y evaluar el impacto micorrítico sobre el crecimiento temprano de plántulas de Tara en condiciones de invernadero. Los resultados mostraron que la tara se asoció principalmente con hongos micorríticos arbusculares de la familia Glomeraceae, notablemente Rhizophagus spp. La micorrización controlada con esporas de R. irregularis mejoró significativamente el crecimiento de tara en invernadero, así como la absorción de nutrientes como el fósforo (P) y el nitrógeno (N). Por lo tanto, C. spinosa podría ser considerada como “altamente dependiente de la micorriza”. Estos resultados destacan la necesidad de considerar la simbiosis micorrítica arbuscular para mantener en forma sostenible la productividad y estabilidad de las plantaciones de tara.Downloads
